cerebrospinal fluid ( csf ) levels of gamma-aminobutyric acid ( gaba ) homocarnosine and ornithine were markedly elevated with inh therapy ( providing evidence for substantial inhibition of gaba aminotransferase activity and increase in gaba in the cns ) , but no correlation was found between the degree of gaba elevation in the csf and the clinical response .
