Neurochemistry of GABAergic system in cerebral cortex chronically exposed to bromide in vivo.

Neurochemical correlates of GABAergic synaptic transmission [binding, uptake, metabolism, and tissue content of gamma-aminobutyric acid (GABA)] were investigated in the cortex of rats that had been given 27 mM bromide in drinking water for periods of time ranging from 1 day to 1 month. No effect of bromide on any of the parameters was found and it is concluded that chronic administration of bromide has no profound effect on GABAergic inhibitory system in the rat cortex.
