GABA as the pallidothalamic neurotransmitter: implications for basal ganglia function

Brain Res. 1981 Feb 23;207(1):195-9. doi: 10.1016/0006-8993(81)90693-4.

Abstract

GABA levels, high affinity GABA uptake and glutamic acid decarboxylase levels are reduced in rat ventroanterolateral thalamic nucleus after destruction of the entopeduncular nucleus with kainic acid. This is strong evidence that GABA is an entopedunculothalamic neurotransmitter. The striatoentopeduncular pathway is also GABAergic. Thus the function of the corpus striatum may be to disinhibit the thalamus.
