There are ganglion cells in the toad's retina which respond to sudden changes in diffuse light levels with bursts of spikes at “on” and “off”.
New results from experiments in freely moving unrestrained toadsBufo bufo (L.) with chronically implanted twin micro recording electrodes show that theoff response of these neurons fail to occur if the animal closes its eye completely.
The results may indicate efferent inhibition in retinal networks.
