title: [Correlation between different forms of trace phenomena in the activity of rabbit visual cortex neurons].
abstract: Plastic changes in the components of the unit responses in the rabbit visual cortex (VC) in the course of electrical stimulation (with different parameters) of the lateral geniculate body (LGB) were compared with the capacity of the same units for trace driving to the LGB preceding stimulation. Potentiation of inhibition (inhibitory pauses) in reponse to electrical LGB stimulation is the main plastic phenomenon in the activity of VC units. Trace driving is characteristic predominantly of units with enhanced plasticity of the excitatory sign, a tendency toward epileptiform activity after LGB tetanization. In most cases inhibitory reaction is expressed in weakening of the periodic component of neuronal activity corresponding to the frequency of stimulation. The level of trace suppression of periodicity positively correlates with potentiation of the inhibitory pause during prolonged LGB stimulation.
