GABA neurotransmission plays a role in brainstem circuitry responsible for jaw movements. We investigated the developmental relationship between terminals expressing GAD67 and GABAA receptor β23 subunit expression within the trigeminal motor nucleus. GAD67 immunoreactivity was intense throughout development. Neuropilar β23 immunoreactivity emerged during the 2nd postnatal week. Our data provide anatomical evidence for a GABAergic innervation of neonatal trigeminal motoneurons and suggest that β23 subunit expression is developmentally regulated in trigeminal motoneurons.
