Summary
- 1.
Among neurons responding to repeated flashes a group has been distinguished which does not form a conditioned reflex to time.
- 2.
Against a background of general activation of some and inactivation of other neurons, stabilization of spike discharge patterns was observed in the course of repetition of the stimulus.
- 3.
The stabilization of unit responses thus developed was disturbed by omission of even one stimulus in a series or by pairing a novel (acoustic) stimulus with the flash. Recovery of stabilization was observed in the course of repetition of the phtic stimulus.
- 4.
It is postulated that stabilization of unit responses is related to postactivation potentiation of excitatory and inhibitory synapses in a neuronal network with lateral inhibition.
