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

Neuroscience Institute, Helen Wills


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


Dr. David Greenberg, Center of Advanced European Studies and Research, Bonn, Germany

Neuroscience Institute, Helen Wills


Abstract:
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 >

Grounds for Science-The deceptiveness of perception

Presentation | March 23 | 6:30-8 p.m. |  Scarlet City Espresso Bar


3960 Adeline, Emeryville, CA 94608

Dylan Paiton, Vision Science Graduate Group

Science@Cal


Optical illusions and visual hallucinations are highly unusual. How is it that we are able to see something that is not really there? Dylan will outline standard methods that neuroscientists use to better understand how our brains process light, and introduce a theory for conscious vision that has guided decades of computational and experimental neuroscience.
