Abstract:
:Cats were kindled in the amygdala. After completion of kindling, their EEG was monitored almost continuously by a computer system which allowed the detection of spontaneous seizures and the quantification of interictal spikes. The relationships between seizures triggered by stimulation, spontaneous seizures, and interictal spikes in kindled and contralateral amygdalas were examined. Very few spontaneous seizures were observed; their occurrence appeared facilitated by a few triggered seizures after a long seizure-free interval. Stimulation-triggered seizures were followed first by a decrease in spiking activity during a few hours and then by an increase which could take 3 to 8 days to return to baseline. Spontaneous seizures were also, but less systematically, followed by such a sequence. Spontaneous seizures could occur when the interictal spiking rate was high as well as when it was low. It is concluded that, in the fully kindled cat, interictal spiking appears to be mainly regulated by the occurrence of seizures; the rate of spiking appears to have no bearing on the probability of occurrence of spontaneous seizures. Hence, seizures and interictal spiking could be generated by separate pathophysiologic mechanisms, the seizure-generating mechanism influencing the spike-generating mechanism but not the reverse.
