Altered oscillatory dynamics of CA1 parvalbumin basket cells during theta–gamma rhythmopathies of temporal lobe epilepsy
Recent reports in human demonstrate a role of theta–gamma coupling in memory for spatial
episodes and a lack of coupling in people experiencing temporal lobe epilepsy, but the
mechanisms are unknown. Using multisite silicon probe recordings of epileptic rats engaged
in episodic-like object recognition tasks, we sought to evaluate the role of theta–gamma
coupling in the absence of epileptiform activities. Our data reveal a specific association
between theta–gamma (30–60 Hz) coupling at the proximal stratum radiatum of CA1 and …
