Irving Epstein has been named AAAS Fellow


In recognition of his contribution to the study of oscillating chemical reactions, Irving Epstein, the Henry F. Fischbach Professor of Chemistry, has been selected as a Fellow in the American Association for the Advancement of Science (AAAS).

Epstein, who in his 45 years at Brandeis has served as Provost and Dean of the Arts and Sciences, said he was honored to receive the award from the AAAS. “I’m delighted and grateful for the recognition,” he said. “It’s always nice to be appreciated by fellow scientists.”


Inside the Marder Lab

Marder Office MobileProfessor Eve Marder’s office door is unmistakable. Tucked between the certificates, accolades, official photos, and award plaques that plaster her lab’s walls, her office door is decorated with a collage of fading photos of students and yellowing cartoons of lobsters and crabs. Inside the office, the shelves are crammed with neuroscience books and stacks of primary and review articles published by her lab throughout her career. But among all of the awards and publications there’s something else that draws your eye. Hanging just above her computer is a homemade mobile built by a former student. Dangling from the mobile are photos of lab members and important scientific figures, faces and images gently pirouetting and circling around one another just above Marder’s head.

Now Marder has another award to add to her vast collection. In June 2016, she was announced as a winner of the Kavli Prize in Neuroscience. Marder shares the Prize with Carla Shatz, of Stanford University, and Michael Merzenich, of the University of California, San FMarder Office Doorrancisco. The award was given to these scientists “for the discovery of mechanisms that allow experience and neural activity to remodel brain function.” The Prize includes a gold medal ceremony and a one-million-dollar award (to be split among the winners), which will be conferred by His Majesty King Harald V of Norway in Oslo in September 2016. First awarded in 2008, the Kavli Prize was established to recognize scientific achievement and to honor creative scientists in the fields of Neuroscience, Astrophysics, and Nanoscience.

The illustrations of lobsters and crabs on Marder’s office door pay homage to the creatures that her lab has used as research subjects to shed light on the fundamental rules that govern how nervous systems function. Her life’s work has been studying a group of neurons called the stomatogastric ganglion (STG). These neurons control rhythmic chewing and filtering of food through the stomachs of crustaceans like crabs and lobsters. The STG is a relatively small (~30 neurons) circuit of cells. It can be dissected out from the animal and placed in a dish, where it can continue to function for up to weeks at a time. In the dish, the neurons will continue to produce electrical rhythms as if the stomach were still chewing and filtering. These electrical rhythms can be studied using a technique called electrophysiology where changes in cell voltage are measured and recorded. The STG contains well-studied central pattern generators (CPGs), circuits that produce rhythmic patterns without sensory feedback. In fact, insight gained from studying the general principles involved in STG activity has given neuroscientists a better understanding of CPGs involved in human behaviors including walking, sleeping, and breathing.

Because the STG is robust and relatively simple, it makes an excellent model to study how neural circuits work. Gina Turrigiano, a colleague at Brandeis, has written that the ideas Marder and her lab developed from studying this system have “catalyzed paradigm shifts in fields as diverse as neural circuit function, computational neuroscience, and neuronal homeostasis…Her ideas have proved to be highly generalizable, and have fundamentally changed the way neuroscientists think about these problems.”

Neuroscientists used to think that the brain was wired like an electronic circuit board. In other words, neurons were wired together via simple connections that could only be “on” or “off.” When all the connections were turned on, the circuit produced a single behavior. Understanding the brain was thought to be as simple as determining how each neuron was physically connected to all others. While working as a graduate student at the University of California San Diego, Marder made a discovery that questioned this dogma. She found that neurons in the STG release acetylcholine in addition to the already known neurotransmitter, glutamate. This result, published in 1974, suggested that neuronal connections could be turned on in more than one way. Her discovery was instrumental in shifting how neuroscientists think about nervous systems. It could no longer be assumed that a simple connection diagram was sufficient.

Further work uncovered many different neuromodulators (neurotransmitters and peptides hormones) that could modulate or alter the neurons’ rhythms of the STG. Dr. Marder found that release of these neuromodulators could shift the activity of the neural circuit without changing any physical connections. This shift can happen very quickly and be long lasting. In addition, neuromodulation can also induce certain neurons to synchronize with different circuits switching their activity to coordinate with one circuit (like the ‘chewing’ circuit) and then to another (like the ‘filtering’ circuit). Both of these findings opened new questions for the entire field of neuroscience. A neural circuit with the same physical connections could have many different output activities so that even simple neural circuits could accomplish a surprising variety of tasks.

Partial Summary of Neuromodulation of the STG, see Marder (2012) Neuron 76:1–11.

Much of the Marder lab’s work in recent years has grown from this initial work in neuromodulation. With so much flexibility of activity, it became important to explore how these systems are able to maintain stability. Although a neuron can live over 100 years, the components of that neuron, including proteins that make up ion channels, constantly change on a timescale of seconds to weeks. Marder worked in collaboration with Larry Abbott and his lab to study how neurons maintain appropriate activity despite such rapid turnover. This work resulted in theoretical models suggesting that neurons have an intrinsic “set-point.” An individual neuron mediates changes in ion channels to produce a specific desirable activity output. This work informed our understanding of how neurons and nervous systems are able to be both plastic, but also to remain functional in a constantly changing environment. It has given rise to work investigating how synapses are able to respond to changing activity or “synaptic scaling” and research into how neurons determine their “set-point” at a molecular level.

Many of the numerous primary and review papers stacked in Marder’s office have been co-authored by some of her almost 80 graduate students and post-docs. These papers have been the work of both experimentalists, who gather data from real neurons, and theorists, who use computers to make hypothetical models of neurons. The collaborative working environment lends strength to the work completed in the Marder lab and forces students and post-docs to explain their work to peers with very different skill sets. It also gives lab members an opportunity to use both theory and experiments to cooperatively build stronger models and to design better experiments. As one example of this, Marder and Abbott together developed the dynamic clamp tool. Using this tool, real biological neurons are connected to model neurons generated within computer programs. This system, now used by scientists all over the world, makes well-controlled manipulations while still probing a dynamically complex biological system.

Wandering through the Marder lab on any given day, it is always buzzing with students and postdocs at computers, doing dissections, or popping into Marder’s office for a quick chat and some chocolate. Currently, the Marder lab is investigating variability in neural circuits. Scientists often view variability as a result of experimental error and attempt to minimize it through averaging over multiple trials. Marder’s approach has revealed that variability is a natural part of how neurons and circuits are constructed and can reveal very important information about how these systems work. Both experimental and theoretical work from the Marder lab has shown that neurons with widely varying characteristics can exhibit nearly identical activity patterns. Thus rather than finding the average properties of a neuron, it is crucial to understand how functionality is maintained in the presence of this variability.

One way the Marder lab currently studies this variability is using temperature change, a physiologically relevant stimulus for crabs who live in varying depths of water throughout the year. Understanding more about how different neuromodulators affect the activity rhythm continues to be an ongoing project since approximately 50 neuromodulators have been discovered in the STG. Other lab members are interested in observing variability in the morphology of different cell types. STG neurons visually have a cell body with a single axon that branches many times so that the cells look less like a traditional ‘neuron’ image but rather a cell body connected to something that looks like a tangled ball of hair. Other work in the lab is interested in investigating where different ion channels are located on this highly branched and complex structure.

To those scientists who have met Dr. Marder she is a source of inspiration and advice. She clearly enjoys engaging with younger scientists especially graduate students and postdocs and many of them have experienced her mentorship throughout their careers. Barbara Beltz of Wellesley College wrote of Marder “It has been clear to me for a long time that although I had PhD and postdoctoral advisors who were supportive and kind, it was Eve who was the most influential mentor in my career.” Marder provides supportive encouragement always paired with frank honesty sometimes in the form of tough love. Ted Brookings, a former Marder lab post-doc says that Marder takes mentorship very seriously and her greatest pride as an advisor is not in selecting the most brilliant people but instead seeing the evidence of how much they have grown during their time in the lab. Many female scientists in particular see her as a trail-blazer and those who have been to her office find the life-sized cutout of Xena Warrior Princess to be appropriate decor.

Working at her undergraduate alma mater, Brandeis University since 1978, Marder helped to build one of the first undergraduate neuroscience programs in the country and a highly regarded neuroscience PhD program. Even as a senior professor, Marder often teaches the Principles of Neuroscience course taken by upper-level undergraduates and required for incoming graduate students. She is unique among the faculty for teaching the course using the blackboard rather than Powerpoint and begins each year with a new bucket of large colorful sidewalk chalk. According to a former Marder lab graduate student, Marder’s teaching permeates everything she does, whether she’s in front of the classroom, having a personal sit down in her office or giving a grand seminar.

Marder received hundreds of congratulatory emails from colleagues and former students and post-docs after the announcement of the Kavli Prize. The extensive body of research from Marder and her students, using the STG, has revealed fundamental properties that apply to all nervous systems. One of her colleagues at Brandeis University, Leslie Griffith has written “Her work has provided a platform for much of our current cellular understanding of circuit function and stability and the mechanisms by which circuits negotiate the flexibility/stability trade-off.” The homemade mobile rotating above her head in her office appears to capture the essence of how Marder views her work and her lab – old and new people constantly in motion orbiting groundbreaking discoveries in neuroscience.
