Changes in Physiological and Pathological Behaviours Produced by Deep Microelectrode Implantation Surgery in Rats: A Temporal Analysis

Figure 1

Representative EEG recordings from animals in the epileptic group. (a) Representative FR observed through the microelectrodes placed in the CA1 region. (b) Representative epileptiform activity observed in CA3. The seizure pattern was characterized by spike-wave activity characteristic of seizures of intensity 5 on the Racine scale. Abbreviations: EEG: electroencephalogram; FR: fast ripples; CA: cornu ammonis; mo: molecular cell layer; gr: granule cell layer; po: polymorphic cell layer; py: pyramidal cell layer; rad: radiatum cell layer.
