EFFETTI DELLA SOMMINISTRAZIONE SISTEMICA DI ACIDO KAINICO SULLA TRASMISSIONE GABAERGICA E GLUTAMATERGICA IN DIVERSE AREE CEREBRALI

: In the present study that Authors have investigated the effects of systemic injection of kainic acid on aminoacidergic transmission of different rat brain regions. Kainic acid has been used to produce an experimental model of limbic epilepsy characterized by two different phases (KA1 and KA2). Results obtained show a significant decrease of glutamic and aspartic acids (excitatory aminoacids) and glicine and taurine (inhibitory aminoacids) in both phases at hippocampal level. On the contrary GABA concentration seems to be increased.
