Avian hypothalamic neurons demonstrate a developmental increase in outward current.
E12 hypothalamic neurons exhibit robust phasic action potentials compared to E8.
Kv1.2, Kv1.3, and Kv1.5 mRNA is present in embryonic avian hypothalamic neurons.
Increase in Kv1.2 and Kv1.5 likely contributes to electrophysiological changes.
