[Electrophysiology of the telencephalic cortex in reptiles (lacerta galloti); EEG and evoked potentials (author's transl)].

EEG recordings were made on the telencephalic cortex of the saurius Lacerta galloti by means of chronically and acute implanted electrodes. In acute experiment cases, the animal was curariced and given artificial respiration. In chronic experiment cases the recordings were made extradurally, epicortically and subcortically. Evoked potentials were obtained by optical, acoustic and somatosensory stimulations. The results show two main aspects: 1. High amplitude slow waves. 2. Very abundant spindles of high frequency. They also show clear responses to sensorial stimuli but without precise topographical localization.
