GABA enhancement of [3H]dopamine release from slices of rat striatum: dependence on slice size.

The effect of GABA on potassium-evoked tritium release from two sizes of ribbon of rat striatum previously loaded with [3H]dopamine was studied. GABA had no effect on the release of tritium from 100 x 100 mum ribbons but produced a dose-related enhancement of potassium-evoked tritium release from 250 x 250 mum ribbons. The enhancement was unaffected by the… CONTINUE READING
