Psychophysics of spatial frequencyadaptation using square-wave gratingsWednesday, August 29, 12Note that the two patterns on the right are identical. Now let your eyes scan back and forth overthe long red bar on the left for about a minute, and then look at the small red square on the right.Do the upper and lower right patterns still look the same? How are they different? It is believedthat populations of neurons with different spatial frequency tuning are responsible for thiseffect.44
Contrast sensitivity of some V1neuronsOne can characterizethe “tuning” orspatial filteringproperties of a celleither by mapping outthe response <strong>to</strong>points of light, or asfor retinal ganglioncells, by mapping outthe response <strong>to</strong>sinusoidal gratings ofvarious spatialfrequencies.Wednesday, August 29, 12From Wandell Book: Spatial frequencyselectivity of 6 neurons in V1 macaque.DeValois, 198245
