Neural gain control: ecological justification and characterization | ||

One of the most widely noted nonlinear properties of neurons is gain control: the modulation of response sensitivity based on environmental conditions. I'll describe some of our recent work linking gain control behaviors in visual and auditory neurons to the statistics of natural images through Barlow's Efficient Coding Hypothesis. Time permitting I'll also describe techniques for experimental characterization of gain control behaviors in neurons, and the implications of these ideas for perception. | ||
