Abstract
Functional peculiarities of paralemniscal subdivision of the thalamocortical system were examined in normal Wistar and in WAG/Rij rats genetically prone to absence epilepsy. In 6-7-month-old WAG/Rij characterized by developed epileptic activity, the response of cortical somatosensory neurons to single electrical stimulation of the posterior thalamic nucleus was phasic, whereas in normal Wistar rats, similar reaction was tonic. The study views this phasic response as neural equivalent of spike-wave discharges known as typical EEG symptom of absence epilepsy.
