Pyramidal neurons (PNs) are the principal cells of the cerebral cortex, and despite their general similarity from area to area, must somehow participate in a diversity of sensory, motor, and memory-related computations.  But how exactly do these neurons work? Despite a century of neurophysiological study and 50+ years of modeling, the “rules” that determine how synaptic inputs are combined within PN dendrites remain poorly understood, and the way PNs contribute to cortical circuit function remain obscure.  This talk will describe recent progress in our understanding of PNs as computing devices, and following an approach that combines neurophysiological experiments, biophysical modeling, natural image statistics, and engineering practice, will explore the possible role of PN dendrites in a key visual computation — object contour detection.

This seminar is open to faculty, scientists, and students from Max Planck Florida Institute for Neuroscience (MPFI), Florida Atlantic University (FAU), and the Scripps Research Institute Florida, located on FAU’s John D. MacArthur Campus in Jupiter, Florida. If you belong to an institution outside of the Jupiter campus and would like to attend, please send a request to seminars@mpfi.org
