DESCRIPTION:Speaker: Lukas Groschner\nhosted by Maximilian Joesch\nAbstract
 : Nonlinear\, multiplication-like operations carried out by individual ner
 ve cells greatly enhance the computational power of a neural system\, but 
 our understanding of their biophysical implementation is scant. I pursue t
 his problem in the motion vision circuit of Drosophila\, where neural acti
 vity and connectivity are highly stereotyped. I record the membrane potent
 ials of direction-selective T4 neurons and of each of their five columnar 
 input elements in vivo in response to visual and pharmacological stimuli. 
 Electrophysiological measurements and conductance-based simulations sugges
 t a passive multiplication-like interaction between two distinct types of 
 synapse on the T4 dendrite. My talk will provide a detailed biophysical ac
 count and an intuitive understanding of how a single neuron uses multiplic
 ative disinhibition to compute the direction of visual motion.
