CorticalCells: Contrast Response Functions from Visual Cortical Cells
Description
The responses in impulses/second of 6 cells recorded in the macaque cortex in visual areas V1 and V2 to a series of contrasts of drifting sinusoidal gratings of optimal location, orientation, size and spatial frequency.

Details
Extracellular recordings of cells from macaque visual cortical areas V1 and V2. Simple and complex cells were differentiated by whether or not the response rate, $f_0$, was greater than the amplitude of modulation at the drift rate, $f_1$. If $f_1 > f_0$, the cell was classified as a simple cell and the value of $f_1$ is reported; otherwise the cell is classified as a complex cell and the value of $f_0$ is reported. In both cases, the units are in impulses/second.
