Although the presence and importance of oscillations in cortical structures is well-documented, little is known about this rhythmic activity in subcortical areas. In waking guinea pigs, during their inattentive rest, local field potentials (LFPs) were recorded simultaneously in eight brain structures. In the cortical areas (prefrontal and entorhinal fields, hippocampus, dentate gyrus) and subcortical ones (medial and lateral septal nuclei, central nucleus of amygdala, and supramammillary nucleus), different types of oscillations were observed: delta (0.

Temporal lobe epilepsy (TLE) is one of the most common forms of epilepsy, characterized by hippocampal sclerosis and memory deficits. It is well-documented that intrinsic neuronal oscillations and provided by them communications between brain structures are of importance for cognition. Epilepsy disturbs these brain rhythms and presumably therefore affects memory.
