CENTRIFUGAL IMPULSES IN RABBIT'S RETINA

Abstract
By recording with microelectrodes from the rabbit''s retina and stimulating its optic nerve it was possible to demonstrate a small spike of very much longer latency (3-4 times) than the direct antidromic spikes. This spike does not stand stimulus repetition well, nor does it stand myanesin. It cannot be initiated by light, and is prevented by light adaptation from appearing. The evidence is conclusive in showing it to be a synapsed centrifugal spike.
