Hyperpolarization-activated inward current in histaminergic tuberomammillary neurons of the rat hypothalamus.


1. Intracellular recordings were obtained from histaminergic tuberomammillary (TM) neurons of rat hypothalamus in an in vitro slice preparation. The properties of a time- and voltage-dependent inward current activated on hyperpolarization, Ih, were studied by use of the single-electrode voltage-clamp technique. 2. The activation curve of Ih was well fit by… (More)
