Abstract

Single cell recordings were made from on centre retinal ganglion cells in the cat. Three types of stimuli were used in the study: a 0.3 degree spot flashed in the centre of the cell's receptive field, an annulus flashed in the receptive field peripheral, or a centre spot and peripheral annulus presented together. The purpose of the study was to determine if response differences between Group I and Group II cells (transient and sustained cells) held at 3 adaptation levels. The response differences reported in earlier studies were found to exist at a high (1.23 log cd/m2) and medium (0.23 log cd/m2) background but not a low background (-1.76 log cd/m2). Speculations concerning the neurophysiological basis of the results are made; also the functional significance of these two types of cells is discussed. (Journal received 21 March, 1975).
