Popis: | Extracellular concentrations of γ-aminobutyric acid (GABA), glutamate (Glu) and aspartate (Asp) were determined by microdialysis in rat hippocampus during various amygdaloid kindled stages. The values of GABA and Glu were increased 3–4 times in C2–C3 stages in comparison with the values in control animals. After reaching the C5 stage, these values were increased 3–7 times. However, the concentration of Asp decreased depending on the kindling stage, reaching the lowest value of 33% in comparison with the normal value. The observed changes may be related to kindling induced seizures. |
