Naegele Teaches Neuroscience to Tibetan Buddhist Monks

ETSIArticle_Rutland_Magazine_Winter_2016[1]

In June, Jan Naegele, professor of biology, professor of neuroscience and behavior, traveled to Mundgod, India to teach Tibetan monks through the Emory-Tibet Science Initiative (ETSI), a program promoting “the convergence of science and spirituality as two complementary systems of knowledge,” according to the Emory Tibetan Partnership. ETSI was founded as a pilot in 2006 by Emory University at the bequest of the 14th Dalai Lama. Naegele’s journey, which she took together with her husband, Dr. Paul Lombroso, was described in the Winter 2016 issue of Rutland Magazine, in an article featuring many photographs provided by Naegele.

Janice Naegele, professor of biology, professor of neuroscience and development, is the co-author of a new paper titled, “Convulsive seizures from experimental focal cortical dysplasia occur independently of cell misplacement.” It was published in Nature Communications on June 1.

Brain malformations called focal cortical dysplasia are typically formed during human embryonic cortical development and are a common cause of drug-resistant epilepsy and cognitive impairments. One of the causes of cortical dysplasia is improper migration of developing cortical neurons. Failure to reach their correct destinations in the cerebral cortex and dysregulated growth leads to the formation of growths or tubers in regions of cerebral cortex. These abnormal growths don’t wire up properly with other cortical neurons and exhibit seizure activity. In this multi-lab collaborative study, the researchers show in mice with experimentally-generated cortical malformations that there is an increase in growth-associated signaling molecules in experimentally-generated cortical tubers associated with seizures. Blocking this signaling cascade with the molecule rapacycin from early stages can prevent the neuronal misplacement, tuber-like growths, and seizures, but once rapamycin is discontinued, the seizures return. Despite the adverse side-effects of taking rapamycin, these findings suggest that life-long treatment with rapamycin may be required in individuals with focal cortical dysplasia, in order to prevent the re-occurrence of seizures and tubers.

The paper is co-authored with Felicia Harrsch, Naegele’s former lab manager, and researchers at the Yale University School of Medicine.

Support Wesleyan Researchers in Crowdfunding Pilot

Four Wesleyan academic departments, from psychology to dance to chemistry to biology, are competing for grant funds through a new crowdfunding site specifically designed for research project fundraising.

experimentExperiment.com’s Challenge Grant for Liberal Arts Colleges asked scientists to define a scientific research question for the crowd with a prize for the project with the most backers. The pilot launched on Feb. 24 and concludes March 25.During this 31-day period, the goal is to reach $4,000 in funding. If so, the team is granted the money. If not, they receive nothing and no one’s pledges are charged. By backing a project, participants will receive updates, results and data from project creators.

Wesleyan research include how the brain prevents risky-decision making/addiction; the effects of using artificial sweeteners; controlling seizures with light; and the effectiveness of somatic mind-body practices on victims of the war.

On Wednesday, March 16 at 11:59 p.m., Experiment will award the project with the most backers $2,000 directly through their project page.

High School Student, Mentored by Wesleyan Neuroscience Program, Finalist for Research Prize

Jan Naegele is one of 19 women faculty in the country to receive a Drexel Fellowship.

Jan Naegele

A high school student from New York, who is mentored by a faculty member and a graduate student in Wesleyan’s Neuroscience and Behavior Program, is one of the top four finalists for the Neuroscience Research Prize, awarded by the American Academy of Neurology and the Child Neurology Society.

As a recipient of the prize, Armonk, N.Y. resident Ryan Infante will receive a $1,000 cash prize and per diem for expenses at the 45th Annual Meeting of the Child Neurology Society in Vancouver, B.C. in October 2016. He will present his stem cell transplantation research during the Child Neurology Society meeting.

Infante, currently a senior at Byram Hills High school in Armonk, N.Y., completed this research last summer while working with Janice Naegele, professor of biology, professor of neuroscience and behavior, and graduate student Dan Lawrence, a BA/MA who majored in neuroscience and behavior in 2015.

Infante was initially guided by his high school science teacher to carry out extensive reading and research about neuroscience.

“When he first contacted me, as a sophomore in high school, he had already read 12 journal articles and had written a review paper that he presented to his science class,” Naegele said. “He became fascinated by work on stem cell transplantation to repair the hippocampus in rodent models of epilepsy and he wanted to learn more about the types of neurons that we study, which utilize the neurotransmitter GABA.”

Throughout his junior year of high school, Infante and Naegele corresponded over email and held frequent Skype discussions. And last summer, Naegele welcomed him to Wesleyan to conduct research in her lab. Infante, at that time, had read many papers on a method called CLARITY—a new way to make brains transparent—to allow scientists to peer into the center of the brain.

Infante worked with Naegele and Lawrence to collect a large number of embryonic and postnatal brains from transgenic mice expressing fluorescent proteins that light up developing and migrating GABAergic interneurons in the embryonic brain.

“When Ryan came to my lab, he and Dan made careful observations of the gradual clearing of the tissue and the process of making opaque brains transparent,” Naegele said.

Infante learned how to use a 3-D printer to make special chamber slides to hold the embryonic brains for microscopy.

“This was a clever modification of the protocol and with this modification, Dan and Ryan examined the brains and also modified protocols for doing additional fluorescent stains in the intact brain tissue,” she said.

Over the past 25 years as a faculty member at Wesleyan, Naegle has welcomed 10 high school students for a summer research project. Most of them are still in science–either attending graduate school, medical school or combined programs. Among them is Elizabeth “Lizzie” Paquette ’16, who ended up matriculating to Wesleyan and is currently a triple major in computer science, mathematics and neuroscience.

“I am so impressed by the capacity for high school students to carry out innovative research with our own Wesleyan students and I’m very proud of both Ryan and Dan,” said Naegele.

Infante was admitted early decision to the University of Pennsylvania, and Lawrence is working on his master’s thesis, and plans to apply to medical school next year.

Wesleyan faculty members played key roles in StemCONN 2015, Connecticut’s stem cell and regenerative medicine conference, held April 27 in Hartford, Conn.

Janice Naegele, professor of biology, professor of neuroscience and behavior, director of the Center for Faculty Career Development, served on the conference’s organizing committee for the second time this year.

Gloster Aaron, associate professor of biology, associate professor of neuroscience and behavior, spoke at the conference on “Investigating how transplants reduce seizures: brain slice electrophysiology and ontogenetic stimulation of transplanted cells.” He discussed the collaborative work being done by his lab and those of Naegele and Laura Grabel, the Lauren B. Dachs Professor of Science and Society, professor of biology, which aims to heal damaged areas of the brain that are the source of seizures in temporal lobe epilepsy by providing newborn neurons to those areas. The goal is for the newborn neurons to replace dead neurons and repair broken neuronal circuits that are thought to be a cause of temporal lobe epilepsy.

Nearly 500 scientists, business leaders and students attended the event, which is held every two years. The event was also attended by many Connecticut officials, including Gov. Dannel Malloy, U.S. Sen. Chris Murphy, U.S. Congresswoman Rosa DeLauro, Connecticut State Rep. Lonnie Reed, and Hartford Mayor Pedro Segarra. The conference was sponsored by Wesleyan, as well as Yale University, the University of Connecticut, the Connecticut Academy of Science and Engineering, Yale-New Haven Hospital, the City of Hartford, and other companies and non-profit organizations.

Psyche Loui, assistant professor of psychology, assistant professor of neuroscience and behavior, was awarded a grant of $20,000 in March from the GRAMMY Foundation Grant Program to study a musical biofeedback-based intervention for epilepsy.

The grant will fund three different studies that combine EEG sonification, translational research and basic neuroscience for this type of intervention. Loui anticipates that the results will apply music technology as a possible solution to a neurological disorder affecting 65 million people worldwide.

Loui noted that for the approximately one-third of patients with epilepsy who don’t respond well to seizure medication,

Faculty, Students Invited to Workshops on Contemplative Pedagogy Feb. 19

How do faculty help students, and themselves, thread a path through an ever-growing body of information? What practices can faculty and students find that enable them to bring a clear and sustained focus to their work in the classroom and the laboratory?

Through two workshops and discussions, held Feb. 19, participants can consider how one might approach teaching from a contemplative perspective, in both the long and short term. Faculty and students will experiment with the adaptation of several traditional contemplative practices to classroom situations including “stilling” (breath and body awareness), contemplative writing, “beholding,” and explore how these might be instantiated in a classroom, laboratory or personal practice.

Michelle Francl, professor of chemistry on the Clowes Fund for Science and Public Policy at Bryn Mawr College, will lead the workshops along with Wesleyan faculty and staff. Francl is a quantum chemist who has published in areas ranging from the development of methods for computational chemistry to the structures of topologically intriguing molecules. She takes a contemplative approach to both, introducing students to practices to help them find stillness and focus, including contemplative writing, and feels strongly that a pedagogical stance that recognizes the role contemplation plays in research and writing — scientific or otherwise — has the potential to deepen students engagement in their work.

“Studies show that contemplative pedagogy – a teaching method to integrate secular meditation and mindfulness into the classroom – can help improve cognitive and academic performance,”

Naegele, Aaron, Student Researchers Published in Journal of Neuroscience

Jan Naegele, Gloster Aaron and several Wesleyan researchers are the co-authors of an article titled “Long-Term Seizure Suppression and Optogenetic Analyses of Synaptic Connectivity in Epileptic Mice with Hippocampal Grafts of GABAergic Interneurons,” published in the October 2014 edition of The Journal of Neuroscience, Issue 34(40): 13492-13504.

Naegele is professor of biology, professor of neuroscience and behavior, and director of the Center for Faculty Career Development. Aaron is associate professor of biology, associate professor of neuroscience and behavior. The article is co-authored by Diana Lin ’15; graduate students Jyoti Gupta and Meghan Van Zandt; recent alumni Elizabeth Litvina BA/MA ’11, XiaoTing Zheng ’14, Nicholas Woods ’13 and Ethan Grund ’13; and former research assistants/lab managers Sara Royston, Katharine Henderson and Stephanie Tagliatela.

Studies in rodent epilepsy models suggest that GABAergic interneuron progenitor grafts can reduce hyperexcitability and seizures in temporal lobe epilepsy (TLE). Although integration of the transplanted cells has been proposed as the underlying mechanism for these disease-modifying effects, prior studies have not explicitly examined cell types and synaptic mechanisms for long-term seizure suppression. To address this gap, the researchers transplanted medial ganglionic eminence (MGE) cells from embryos into adult mice two weeks after induction of TLE.

The researchers found that TLE mice with bilateral MGE cell grafts had significantly fewer and milder electrographic seizures. These findings suggest that fetal GABAergic interneuron grafts may suppress pharmacoresistant seizures.

In this issue of The Wesleyan Connection, we speak with Mike Robinson, assistant professor of psychology, assistant professor of neuroscience and behavior, who joined the faculty in January.

Q: Welcome to Wesleyan, Professor Robinson! Please fill us in on your life up to now.

A: I was born and grew up in France, in the west suburbs of Paris, but my parents are both British, so that makes me bi-national and bilingual. I went to high school in France and decided to go to university to study neuroscience at the University of Sussex in the U.K. Then I went to McGill University in Montreal, Canada to do a master’s and a Ph.D. in experimental psychology. From there, I went to the University of Michigan for a post-doc before coming to Wesleyan. So I’ve almost jumped a country per position.

Q: What brought you to Wesleyan?

A: I was attracted by the balance Wesleyan offers—both the work-life balance, and the work balance between the amount of research and the amount of teaching. I really enjoy both teaching and research, but I always felt like I’d have to compromise one or the other if I went to a research institution or a more teaching-intensive small liberal arts school. I feel like Wesleyan has the perfect balance. Plus the opportunity to be with really high-quality students, which I thought would be really stimulating and almost like working with grad students. I currently have four students in my lab, and so far I’ve been very impressed by them.

Q: What classes are you teaching this semester?

A: I’m teaching one course called “Motivation and Reward.” In the fall, I’ll be co-teaching “Intro to Neurobiology” with Jan Naegele (professor of biology, professor of neuroscience and behavior, director of the Center for Faculty Development), and a research methods course on research in animal behavior. Next spring, I’ll be teaching “Motivation and Reward” again, and an advanced research course looking at where a lot of my research is focused, which is gambling, diet-induced obesity and drug addiction.

Q: Please tell us more about your research interests.

A: I’m interested in understanding how the brain works. I’ve always wanted to do something that helps people in as direct a way as possible, considering I’m not doing human research. I started out doing research on drug addiction. My Ph.D. work looked at the ability that we may have to affect memory after it’s been created and consolidated, either strengthening or weakening it.
