Relationship Between Contrast Adaptation and Orientation Tuning in V1 and V2 of Cat Visual Cortex

Crowder, Nathan; Price, N; Hietanen, Markus; Dreher, B; Clifford, Colin W.G.; Ibbotson, Michael


Previous studies investigating the response properties of neurons in the primary visual cortex of cats and primates have shown that prolonged exposure to optimally oriented, high-contrast gratings leads to a reduction in responsiveness to subsequently presented test stimuli. We recorded from 119 neurons in cat V1 and V2 and found that in a high proportion of cells contrast adaptation also occurs for gratings oriented orthogonal to a neuron's preferred orientation, even though this stimulus did...[Show more]
