such in vivo and in vitro findings suggest that the gaba-induced inhibition of met-enkephalin release took place via the stimulation of specific gaba a and gaba b receptors within the caudate nucleus , whereas the gaba-induced increase of the peptide release might involve some intracellular regulatory processes in striatal neurones containing both gaba and enkephalins .
