Synaptic control of rat supraoptic neurones during osmotic stimulation of the organum vasculosum lamina terminalis in vitro.

1. The effects of osmotic or electrical stimulation of the organum vasculosum lamina terminalis (OVLT) were examined during intracellular recordings (32 degrees C) obtained from ninety-five supraoptic nucleus magnocellular neurosecretory cells (MNCs) in superfused explants of rat hypothalamus. 2. Brief (10-20 s) applications of hypertonic and hypotonic… (More)
