In vivo presynaptic control of dopamine release in the cat caudate nucleus--I. Opposite changes in neuronal activity and release evoked from thalamic motor nuclei.


Halothane-anaesthetized cats implanted with three push-pull cannulae were used to estimate the effects of gamma-aminobutyric acid (GABA) application (either 10(-3) M or 10(-5) M) into the left motor nuclei of the thalamus (either ventralis medialis, or ventralis lateralis) on the firing rate of dopamine cells in the left substantia nigra (caudomedial part… (More)
