Membrane properties of histaminergic tuberomammillary neurones of the rat hypothalamus in vitro.


1. Intracellular recordings were obtained from neurones of the tuberomammillary nucleus in an in vitro explant of the rat hypothalamus. 2. Tuberomammillary neurones were spontaneously active (2.1 +/- 0.6 Hz) at the resting potential which was around -50 mV. Action potential amplitude was 75 +/- 8 mV (n = 9); mean mid-amplitude duration was 1.8 +/- 0.4 ms (n… (More)
