Description: NIH Neuroscience Series Seminar

Dr. Jayaraman lab is interested in establishing causal links between the dynamics of neural circuits and the behavioral decisions that an animal continuously makes as it navigates a multi-sensory world. They aim to uncover how the relevant neural representations and dynamics arise and what specific role they play in shaping adaptive behavior. They use the powerful genetic model organism Drosophila melanogaster for their experiments, many of which rely on monitoring and perturbing the activity of specific neural populations during head-fixed behavior. They rely on a combination of two-photon calcium imaging, whole-cell patch clamp electrophysiology, quantitative behavior, optogenetics, and computational analysis and modeling in their efforts to mechanistically link computation in a higher brain region called the central complex to the fly's behavioral decisions.
