Properties of tuberomammillary histamine neurones and their response to galanin
- 47 Downloads
Histaminergic neurones in the tuberomammillary nucleus possess electrophysiological properties which distinguish them from other neurones in their neighborhood. Their resting potential is −50 mV and they are spontaneously active at about 2 Hz in a slice preparation. They display a transient outward rectification and an anomalous inward rectification. Bath application of galanin (0.1 μM) reduced their firing rate significantly and hyperpolarized them slightly.
