摘要: Stimulation outside the receptive field of a primary visual cortical (V1) neuron reveals intracortical neural interactions. However, previous investigators implicitly or explicitly considered extent spatial summation and, therefore, size classical to be fixed and independent stimulus characteristics surrounding context. On contrary, we found that in macaque V1 neurons depended on contrast, was average 2.3-fold greater at low contrast. This adaptive increase contrast seen cells throughout surround inhibition.
