Abstract
Cortical grating cells respond only and in a contrast-independent way to repetitive bar stimuli (bar gratings), but not to individual bars: their responses behave like the neural correlate of perceptual previous termtexture-constancy.next term We present a recurrent mean-field model for grating response. A first stage consists of idealized simple cell pools with identical preferred orientations, which are coupled by intracortical long-range patchy connections. In the second stage, grating cells sum up the simple cell input. The proposed model shows previous termtexture constancy,next term quantitatively reproduces the responses of macaque monkey grating cells and provides testable predictions of further cellular response properties.
