GABA concentrations in different cerebral areas of bass (dicentrarchus labrax).
In these investigations GABA concentrations in different cerebral areas (cortex, diencephalon, optic lobes and mesencephalon) of bass (Dicentrarchus labrax) were evaluated. According to the results obtained, the GABA, like other chemical mediators (noradrenaline, dopamine, serotonin), investigated in different animal species, shows a variable distribution in the CNS of bass. The highest levels of GABA were observed in the cerebral cortex and the lowest ones in the mesencephalon. Mean values were observed in the diencephalon and the optic lobes. The study of the GABA-ergic system of the CNS of fish, could provide a valid contribution to the comprehension of several biochemical and physiopathological mechanisms responsible for the behavioural activity and/or the appearance of neurotoxic phenomena.
