Abstract
Isolated synaptosomal fractions from mouse forebrains were incubated with [14C]‐γ‐aminobutyric acid ([14C]‐GABA). Release of the accumulated label in high potassium solution was measured. The fractional release dependent upon calcium was decreased by raising the concentration of [14C]‐GABA during labelling but was not affected by altering the time allowed for labelling or the time between labelling and stimulation. These data suggest that extracellular GABA gains rapid access to available intraterminal pools. The relative distribution of the accumulated GABA in different pools can be influenced by the concentration of GABA in the incubation medium but, once ‘stored’, there is no net redistribution of accumulated GABA in the absence of stimulation.
