Abstract

Since Hartline [1] first identified three response types (ON, OFF, and ON-OFF) of vertebrate retinal ganglion cell (RGC) responses in 1938, the properties of ON and OFF RGCs have been well characterized and their function has been investigated extensively. On the other hand, it is not known how ON-OFF RGCs serve animals’ vision. If spikes are evoked evenly and independently by intensity increases (ON) and decreases (OFF) in the ON-OFF RGCs, the resulting spike trains may convey only information about the timing of intensity changes of either direction, whereas more complex temporal features could be encoded if there is an asymmetrical interaction between ON- and OFF-responses [2].
