Seeing where we’re going: a retinal code for self-motion

Seminar: Oxyopia Seminar | March 19 | 12-1 p.m. | 489 Minor Hall

Dr. David Berson, Professor of Medical Science, Chair of NeuroScience, Brown University

Abstract: Self-motion triggers complementary visual and vestibular reflexes supporting image-stabilization and balance. Translation through space produces one global pattern of retinal image motion (optic flow), rotation another. We show that each subtype of direction-selective ganglion cell (DSGC) adjusts its direction preference topographically to align with specific translatory optic flow...   More >

Spike inference for genetically encoded calcium indicators with models of multistep binding kinetics

Seminar | March 19 | 4-5:30 p.m. | 177 Life Sciences Addition

Multiphoton imaging of genetically encoded calcium indicators can detect action potential (AP) evoked fluorescence changes from populations of spatially resolved neurons, but the nonlinear dependence of fluorescence on AP counts and variable indicator expression across neurons make quantitative inference problematic. We developed a biophysical model of GCaMP6s in neurons based on the...   More >
