We discovered that baclofen results in membrane hyperpolarization in NAG neurons in both pups and adults (Fig. 5A). The magnitude of baclofen-mediated hyperpolarization was 8.7 1.6 mV (P13?P15; n 6, four animals; t(5) five.two, p 0.05, paired t test) and11.1 3 mV (young adults; n four, 4 animals; t(3) three.6, p 0.05, paired t test). On the other hand, there were no significant variations in baclofen fnins.2015.00094 responses amongst pups and adults (Fig. 5B; p 0.05).8569 ?Table 1.

A, GABA leads to membrane hyperpolarization in NAG neurons at P13 15 (10 of 13 neurons, six animals), P21 23 (7 of 7 neurons, four animals), and young adult (10 of 10 neurons, five animals).

GABA decreases neuronal activity through both ligand-gated GABAA receptor along with the G-protein-coupled GABAB receptor inside the adult nervous method (Obrietan and van den Pol, 1998). To investigate regardless of whether there is certainly a developmental distinction inside the function of GABAB receptors, we performed electrophysiological studies utilizing baclofen 20 M, a GABAB receptor agonist, in NAG neurons at P13 15 and young adult (9 ?0 weeks). We discovered that baclofen leads to membrane hyperpolarization in NAG neurons in both pups and adults (Fig.
