On Thursday, Feb 26, Lakshmi Chandrasekaran from the Stowers Institute for Medical Research will be on campus,
giving a science lecture talk at 4:10 PM in SCSC163
Title: The Math behind Rhythms and Neuronal Networks
Understanding how human nervous system communicates to achieve coherent message transmission requires an analysis of synchronization tendencies. In the first part of the talk, I will analyze reciprocally coupled clusters of neuron populations. I investigate a two-cluster solution in which all neurons are synchronized within each cluster but the neurons between each cluster are phase locked at non-zero phase with respect to each other. I use Phase Response Curve methods generated under the assumption of pulsatile coupling to predict existence and understand stability of the two-cluster solution. In the second part of the presentation, I will use mathematical models to investigate the basic principles of how sensory information is encoded by neurons in the brain. In particular, I study the olfactory system- the sense of smell. Using biological data of activity patterns generated in mice, which are either awake or anesthetized, I construct simple mathematical models to predict differences in network circuits. Additionally, I will detail the neural dynamics that give rise to varied responses in these diametrically opposite states of brain action. Finally, I will discuss implications of the modeling predictions leading to my future projects.s. Both deterministic and stochastic frameworks will be introduced.
