  • Title: Feline generalized penicillin epilepsy.
    Author: Avoli M.
    Journal: Ital J Neurol Sci; 1995; 16(1-2):79-82. PubMed ID: 7642356.
    Abstract:
    Feline generalized penicillin epilepsy represents an experimental model of generalized spike-and-wave discharges occurring during clinical absence attacks. Spike-and-wave discharges of feline generalized penicillin epilepsy also have a pharmacological profile that is similar to that encountered in human absence attacks. Studies on the respective roles played by the thalamus and cortex in the generation of spike-and-wave discharges indicate that both structures are important in the elaboration of such generalized activity. Moreover, GABAA-mediated, intracortical inhibitory mechanisms are preserved and eventually enhanced at a time when generalized spike-and-wave discharges of feline generalized penicillin epilepsy are recorded. A preservation of GABA-mediated mechanisms in pure absence epilepsy might explain the differences in prognostic outlook that characterizes this type of epilepsy from seizures in which GABAergic mechanisms break down (e.g., generalized convulsive and partial epileptic attacks).
