Our Research Updates in Archways give a snapshot of the Rice ARCHES Initiative’s current work, research progress, and future directions
Adapting for Pandemic Safety
This week Russell Ku, a Research Assistant in the BMED Lab, tells us about precautions the Project CHROMA team is taking based on CDC guidelines.
After the unprecedented COVID-19 pandemic began, Rice University began implementing a system of precautions that are based on CDC guidelines to prevent the spread of the virus and keep community members safe.
These include weekly testing for all members of the Rice community who interact with campus, use of personal protective equipment such as masks and face shields on all parts on campus- both indoors and outdoors, physical distancing, and increasing cleaning and disinfection of buildings, all of which apply to the CHROMA lab as well.

More specifically to the CHROMA lab, the team also made efforts to reduce visit times and physical contact as much as possible to keep our participants safe.
We now give participants links to online questionnaires or printed copies so that they can complete them in the comfort of their own homes and eliminated most high-contact measurements, such as blood pressure, height and weight, and waist measurements. We also give participants the option of electronic or no-contact delivery of some pre-visit forms.
Although Texas has ended its mask mandate and lifted restrictions on building capacity limits, Rice University has not changed its protocols. All of the above-mentioned precautions are still in effect. Any changes that may be made in the future will follow the university’s Research Reactivation Program guidelines.

Our “Wellness Resources” series in Archways highlights outside initiatives supported by Rice ARCHES researchers.
Inside the Chrysalis
This month Dr. Michelle Quist is invited by Dr. Angie LeRoy, a post-doctoral Research Fellow on our team in the Department of Psychological Sciences, to discuss the mental wellness podcast that they are working on together.Dr. Quist is an Assistant Teaching Professor in the Department of Psychology at Penn State University and Founder of the Inside the Chrysalis podcast.
Have you ever felt the urge to fundamentally change in
positive ways? To outgrow bad habits and establish positive ones? We all have
at one level or another, but we always run up against the same problem – growth
is hard.
We learn in elementary school about the metamorphosis of the
caterpillar; the ravenous insect that cocoons itself inside a chrysalis before
eventually emerging as a beautiful butterfly. For us, this process becomes the
symbol of the growth and transformation for which we all strive. The aspect we
never discuss, however, is the magnitude of what is happening inside the
chrysalis. The caterpillar has to break itself down to its most basic elements
before reforming as an entirely new creature. That messy, chaotic process is
the inspiration for our podcast, Inside
the Chrysalis.
The creators of Inside
the Chrysalis are four social psychologists, people who study humans and
how they relate to each other. Our goal is to use our expertise to shed some
light on the transformation process and to help people connect with each other
in the context of shared experiences. Throughout our first season, we will
discuss common issues such as achieving an important milestone and then feeling
unexpected dissatisfaction or persistent imposter syndrome, or the anxiety that
can arise from comparing yourselves to other people. We invite people from a
variety of expertise and industry to candidly discuss what research has to say
about our collective experience, establishing a place for pause, growth,
reflection, and connection.

Check out this message from CPAM’s Director, J. Todd Frazier:
I invite you to participate in our hospital IRB (Internal Review Board) approved survey (PRO#00023826), helping us add to the growing base of information supporting elements or parameters of music composition that lead to relaxation.
Why is this important?
In times like this, where anxiety and stress is rising to unprecedented levels for the general population and especially for healthcare providers, we want to be able to use music in the most effective way to support each other.
We still have a lot to learn about how best to do this, especially for large groups of people we don’t have the opportunity to get to know personally. This survey, and its published results, will help us, and the field of arts in health, make even better decisions on how to use the beauty and mystery of music to respond to health challenges and improve wellbeing.
Click here to help CPAM by taking the survey (have some good headphones ready for the music):
All the music examples of this survey are performed by the study Principal Investigator, Dr. Mei Rui and if you are interested in learning more details about the survey, please see the attached Recruitment Letter.
When the survey is complete, you will be directed to Dr. Rui’s full list of musical performances created for relaxation at: https://soundcloud.com/user-390883826

Playing unfamiliar music to patients could improve music therapy outcomes.
Music can promote brain healing, but scientists are still trying to understand which types of music work best for each patient.

When Melia Bonomo wants to kick back and relax, she turns to music and the gentle melodies of pop star Ed Sheeran. Like many people, the physicist feels her mood lift with certain tunes, a change doctors exploit to improve the health of patients with cognitive impairments. But some patients are unresponsive to music therapy. And it remains unclear exactly what restorative changes music actually induces in the brain. New results from Bonomo, a graduate student at Rice University, Texas, and her colleagues suggest that clues to both of these problems lie in how the brain responds to a listener’s favorite tune. Bonomo was set to share her findings in a session on the physics of the brain at the March Meeting of the American Physical Society earlier last month. (The meeting was canceled due to concerns about the new coronavirus disease, COVID-19, but Physics is reporting on some of the results that would have been presented.)
“Music therapy doesn’t work for everybody,” says Bonomo, who collaborated with researchers at Houston Methodist Hospital’s Center for Performing Arts Medicine. “We wanted to see if we could better understand why that is from how a person’s brain processes music.”
In the study, Bonomo and her colleagues used functional magnetic resonance imaging (fMRI) to monitor the neuronal activity of 25 people as they listened to six audio excerpts. Each person’s set list included their favorite song, a Bach concerto, and an old newscast by Walter Cronkite. The team then translated the resulting fMRI images into network-like maps, with one map for each excerpt per person. To make these maps, the researchers divided the brain into 84 regions and drew a connecting line between two regions if they had similar patterns of activity during an audio excerpt.
Bonomo looked first at the brain maps of participants listening to their favorite songs. Within these networks, she noticed that some regions were more strongly connected with each other than others, forming a “community.” She then found that the networks fell into two categories: those where there were many connections between different communities and those where there were fewer. And interestingly, the category for a participant’s map was predictive of how they would respond to the other five sound clips.
She and her colleagues found that when a participant’s “favorite-song” network had many intercommunity connections but few intracommunity ones, the distribution of connections changed significantly for each of the other excerpts. But when the opposite was true, these connections tended to stay in place, unless the participant was listening to the most unfamiliar sound clips. (For the people in the study, the least known excerpts were a melody from a Japanese opera and a passage of foreign language speech.)
Bonomo and colleagues made network-like representations of brain activity in response to music. The maps indicate that the brain’s response to a favorite song (left)—specifically, the types of connections between regions of activity—predicts how it will respond to other music (center and right).
The fact that networks with more isolated communities are harder to disrupt is well known in network theory, explains Bonomo. Seeing this effect in the brain’s response to music tells us that, for some, forming new neuronal connections—something the brain needs to do to compensate for an injury, for example—may require a bigger auditory stimulus. That could have implications for music therapy, where clinicians select music to foster neuronal connections and help the brain heal. Typically, therapists select popular melodies, such as the classical music of Bach or Beethoven, to stimulate a recovery. But the new study suggests that those pieces might not be the right ones to play for everyone, says Bonomo. Instead, unfamiliar music might be the best bet. Bonomo and her colleagues are currently testing this hypothesis in a study of people with mild cognitive impairment.
Although Bonomo’s work went unpresented at the March Meeting, she did share it on Twitter. Inspired by fellow physicist Douglas Holmes of Boston University, she condensed her planned talk into ten slides that she tweeted out under the hashtag #APS10slides10tweets. She hopes that the tweets will scroll across the screens of others studying how music impacts the brain. While she doesn’t know yet if that has happened, she said that sending the tweets “was a cool way to publicly share a snapshot of my research.”
What do stress, loneliness and lack of sleep have in common? They are all factors that can weaken your immune system and make you more susceptible to COVID-19, according to Rice University’s Christopher Fagundes, an associate professor in the department of psychological sciences who studies the link between mental and immune health.

“In my field, we have conducted a lot of work to look at what predicts who gets colds and different forms of respiratory illnesses, and who is more susceptible to getting sick,” Fagundes said. “We’ve found that stress, loneliness and lack of sleep are three factors that can seriously compromise aspects of the immune system that make people more susceptible to viruses if exposed. Also, stress, loneliness and disrupted sleep promote other aspects of the immune system responsible for the production of proinflammatory cytokines to over-respond. Elevated proinflammatory cytokine production can generate sustained upper respiratory infection symptoms.”
And while this previous research has centered on different cold and upper respiratory viruses, he said “there is no doubt” that these effects would be the same for COVID-19.
Previous studies have indicated that healthy, nonimmunocompromised people who spend less time around others and are exposed to the cold virus are significantly more likely to get sick and experience worse symptoms than those people who get out and socialize.
Fagundes said this can be explained by the way positive emotions buffer against stressors and evoke a favorable immune response, even while extroverted individuals are more likely to be around more people, possibly those who are carrying germs that could make them sick.
It’s an interesting paradox during the global COVID-19 pandemic, Fagundes said, when people are strongly encouraged and in some places required to stay at home to prevent the further spread of the virus.
Another major factor that impacts immune health is sleep deprivation, Fagundes said, which he noted has been demonstrated over and over in previous study of the topic.
“The overwhelming consensus in the field is that people who do not consistently get a good night’s sleep — 7-9 hours for adults, with variation on what is optimal — makes a person more likely to get sick,” he said.
Fagundes said that although alcohol use, certain jobs and other factors make some people more likely to have poor sleep, psychological stress has a tremendous impact on a person’s quality of sleep.
“It’s important also to note that when we talk about stress, we mean chronic stress taking place over several weeks, not a single stressful incident or a few days of stress,” Fagundes said. “An isolated stressful incident does not seem to make a person more susceptible to a cold or the flu.”
However, even absent of poor sleep, chronic stress alone is disruptive enough to the immune system to make people more likely to get sick, Fagundes said.
“Without question, previous work on this topic clearly demonstrates that chronic stress affects our immune system in a way that makes us more susceptible to viruses and colds,” he said. “Just think about college students who get sick after weeks of stress while studying for a big exam.”
Fagundes said the best ways to mitigate the harmful health effects of loneliness and stress during the COVID-19 pandemic are to stay connected with others through communication, particularly video calls.
“There is some evidence that it may be better to video conference versus having a regular phone call to reduce feelings of isolation,” he said. “There’s something about chatting with people and having them visually ‘with’ you that seems to be more of a buffer against loneliness.”
Fagundes also noted that it is important to keep a routine during stressful times.
“This will regulate your sleep and allow you to focus on immediate goals and plans,” he said. “In turn, you will overthink things less and feel more accomplished.”
And if you find yourself worrying nonstop about the situation, it can be helpful to set aside specific “worry times,” Fagundes said.
“People often worry and overthink things because their brain is telling them there is something to solve,” he said. “However, it can be counterproductive after a while. A good technique is to set aside 15 minutes a day where you allow yourself to worry, preferably with a pen and paper. After that, you aren’t allowed to think about the issue for the rest of the day.”
Fagundes said it is also sometimes helpful for people to identify inaccurate thoughts that reinforce negative thinking and emotions.
“People often convince themselves that a situation is much worse than it is by telling themselves things that are not true,” he said. “We call these cognitive distortions. For example, it is common to catastrophize a situation by convincing themselves that the worst-case scenario is the most likely scenario. When people learn to identify and then refute these thoughts, they often feel much better.”

Our “Project CHROMA Personnel” series in Archways highlights the key researchers behind the Rice ARCHES Initiative.
Kristi Parker, M.Ed.
This month Nyla Vela from the Department of Psychological Sciences interviews our Lab Manager in the Biobehavioral Mechanisms Explaining Disparities (BMED) Lab.
Earlier this week I got to sit down with our very own, Kristi Parker, the Lab Manager here at the BMED Lab, and she gave me the ins and outs of what its really like to oversee the incredible projects we have here.
Kristi, a California native who got her master’s in education at the University of Southern California, found herself drawn to the BMED lab due to her interest in Psychology. She says that she is very fascinated with the work the lab is doing regarding connecting the mind and the body.
Before we were lucky enough to have her however, she actually worked as a paralegal for 5 years!
Further, she began to tell me about what her job entails. In her words, she takes care of a lot of administrative work. From scheduling and working with grants to overseeing progress made by all the different projects under the lab’s wing, Kristi could be seen as the glue that keeps this lab together. Serving as an immediate liaison between Dr. Christopher Fagundes, our primary investigator, and the rest of the lab, we are always well informed and on top of our immediate goals as a team.
When asked about what she enjoys about her job, Kristi told me that she really enjoys the participant interaction aspect of the lab. She detailed a story about one participant who, when Project Heart was still doing home visits, would bake cookies and tell stories every visit.
Evidently, Kristi is a caring and hard-working figure here at the BMED Lab. If it weren’t for her, our lab would simply fall apart, so we are very grateful that her interest in learning about others landed her here with us!

Art & Science at the ARO Conference
This month, Melia Bonomo from the Department of Physics & Astronomy tells us about some unique art exhibits at the Association for Research in Otolaryngology conference.
Recently, I had the opportunity to attend the Association for Research in Otolaryngology (ARO)’s 2020 midwinter meeting in San Jose, California with the Raphael Lab. It was a really great opportunity to learn about current research in auditory neuroscience, especially for work relevant to Project CHROMA that is looking at how the ear and brain perceive and process music. An important aspect of doing scientific research is interacting with other scientists to share your results, discuss progress, learn about other work going on in your field, spark new ideas and research directions, and initiate new collaborations — communication really is key to scientific advancements.
In addition to research presentations and posters, there were several neat exhibits at ARO that combined the arts and sciences!
(1) Outside the San Jose McEnery Convention Center, there was a large-scale interactive sculpture (pictured above) called Idea Tree by artist Soo-in Yang, fabricated and installed by Demiurge, and engineered by ARUP. Demiurge give a great description of the connection between art and technology: “The sculpture accepts audio inputs – speech, song, ambient noise – and by interacting with and learning from participants using advanced AI and speech recognition software, these sounds are used to create a dynamic audio composition. Idea Tree is the embodiment of the idea that a convention center is a place where people gather to share ideas and concepts, forming the seeds for these ideas to grow and evolve.”
(2) Inside the Convention Center’s prefunction area, there was a multisensory art exhibit called “Your Eyes On My Ears,” in which visitors listened to accompanying audio while contemplating portraits of individuals wearing hearing aids or cochlear implants. This exhibit was put together by the Droit Pluriel and Foundation Pour l’Audition to provide a unique perspective on hearing loss.

(3) One night of the conference there was a public outreach event at the San Jose Montgomery Theater, “Musae on the Brain: Women in Voice and Science,” which featured a performance by a local women’s vocal ensemble Musae followed by presentations by Sarah Schneider, a speech-language pathologist from UCSF who specializes in understanding and caring for the professional voice, and Dana Boebinger, an auditory neuroscientist from Harvard who studies how humans perceive complex sounds. There was a q&a period afterwards for discussion on how music arises from a combination of human voices, ears, and brains.
Also at ARO, I met Dr. Charles Limb and Dr. Karen Barrett of the The Sound and Music Perception Lab (University of California, San Francisco) who have a National Endowment for the Arts-funded Research Lab like us! Limb and Barrett are studying the cognitive and social processes of arts-based creativity, and how these processes affect learning-related outcomes. Check out their website for more information about their work: https://ohns.ucsf.edu/limb-lab.
Overall, the conference and the associated art exhibits made for a great experience — a big thank you to the Raphael group for supporting me to attend!

Modularity of the Brain
This month Fengdan Ye from the Department of Physics & Astronomy discusses an analysis method being used to study brain activity in Project CHROMA.
In recent years of neuroscience research, it has become more and more popular to view the whole human brain as a functional network. The structure of the human brain network has been studied in relation to cognitive performance, as well as disease progression. Modularity is one of the many ways to quantify the structure of a human brain network, and it’s a concept I have been working with throughout my PhD.
What is modularity? To understand that, we first need a clear picture of what a whole-brain network looks like. A network consists of nodes and links. In our case, the nodes are different brain regions. These regions are usually defined from existing divisions of the human brain, which can be based on either anatomical or functional features of the brain. For example, Brodmann areas are brain regions defined based on the microscopic cellular composition of the brain. The links between these regions can be defined in many different ways. One popular way is to derive the links from functional magnetic resonance imaging (fMRI) data. Specifically, the Blood-oxygen-level-dependent (BOLD) imaging method in fMRI gives information on the level of activity of any brain regions at any given time. A link exists between two brain regions, if they show synchronized activity across a period of time. A link is absent if the activity of two brain regions is not coordinated.
Modularity quantifies how modular the brain network is. The higher the modularity, the more modular the network is. For example, let’s assume we have six brain regions A through F. If brain regions A, B, and C are all linked to each other, and D, E and F are all linked to each other, but there is no link between the first group (ABC) and the second group (DEF), then the network is very modular. Under the context of BOLD imaging, this means the brain has two distinct functional modules: one consists of ABC and the other DEF. The regions within each module always activate together, but regions across modules do not communicate functionally. On the other hand, if there are links between all six regions, then the network is less modular because it is harder to define which regions work more closely with each other. Below is another example of low- and high-modularity networks:
Image: Comparison of networks that have the same number of nodes (circles) and links (connecting lines) but different modularity (M) because of the network organizations.
In research, people not only look at the modularity value of a brain network, but also the compositions of the identified modules. This method has shed light on human cognitive and behavioral function, as well as prognosis and progression of diseases, such as stroke and Alzheimer’s disease.

Connecting with Our Community
This month Dr. Angie LeRoy, a post-doctoral Research Fellow on our team in the Department of Psychological Sciences, discusses community engagement.
In Project CHROMA, we are recruiting individuals over the age of 70 and/or diagnosed with Mild Cognitive Impairment to participate in our study of how music creativity can benefit cognition and social/emotional wellbeing. As part of our efforts to integrate the community with our research goals, we make a concerted effort to enhance our visibility at community events.
We feel that connecting with community members is important, not only to recruit community members to participate in our study, but also to give back to our community through communicating empirical research findings. In doing so, we hope to educate the public about the most recent research in the area of health psychology, with a specific focus on preventing poor health outcomes among our aging population.

Recently, I did a public educational talk about Alzheimer’s Disease and Caring for a loved one with Alzheimer’s, at the annual Rice Alzheimer’s Buddies Symposium. I also discussed strategies that we may be able to use to slow down the progression to Alzheimer’s by early intervention. For example, through the use of music—as we are doing with the Rice ARCHES Initiative.
We received positive feedback from the audience, which consisted of people of all ages and demographics. After the talk, some nursing students who were inspired by hearing about our work, approached our information booth to ask more about the study and inquire about volunteering to work on the project.
Moving forward, our team will continue to prioritize connecting with community members to enhance our visibility and spread awareness!
