[Pseudo-sensations in seizures as a symptom of subcortical epilepsy]

A group of epileptic patients in whom the seizures were accompanied with false sensations was examined. An analysis of the results of the clinico-physiological examinations has shown that such sensations arise on electric stimulation of the thalamic nuclei. This gives one grounds to believe that it is the thalamus which is a structure responsible for the generation of such kind of seizures. This supposition is confirmed to a certain extent by the negative results of surgical intervention on the sensomotor cortex zone in 9 patients. This zone of the cortex is, probably, involved later: as a result of this a complicated cortico-subcortical epileptic system is formed. The leading role in this system belongs most probably to the thalamus.
