Some observations on dynamic properties of receptive field organization of complex cells in cat visual cortex.
The dynamic properties of discharge fields (DFs) of the complex cells in areas 17 and 18 of cat's brain were observed. The sequence of activation for different areas in the DF indicated a concentric arrangement of latency distribution. The DE organization was proved to be dependent closely on velocity of stimulus movement. Twin- or triple-DFs were found for some cells, each responded selectively to one of the opposite directions of movement.
