Bacteriorhodopsin Langmuir Blodgett films were used to construct a 1 D retinal off center receptive field.The photoelectric responses of peripheral and central areas of the artificial receptive field to square wave light signals in temporal domain was determined.The results showed that the peripheral and central areas of the artificial receptive field have the characters of off and on differential respones like the receptive field of an animal respectively.Based on aforesaid,the artificial receptive f...
