I am working on a neural network model of visual perception with relevence to cells
in area V2 of visual cortex. A reviewer of the paper suggested that some of the
model cell properties may be unphysiological. I'd like to know if anyone can give me
references to the following issues.
(1) Do cells in V2 have a non-zero baseline firing rate?
(2) Oriented cells in V2 tend to respond to stimuli of a particular orientation. Do
any cells show below baseline firing rates for stimuli of the opposite (90 degrees)
orientation?
(3) Do any oriented cells in V2 ever show a rebound of activity due to the offset of
a stimulus oriented 90 degrees from the cell's optimal orientation? (a la MacKay
orientation afterimages, for those with a perceptual background)
Any help would be appreciated. Please respond to: gfrancis at psych.purdue.edu
Thanks,
