Abstract
1. Intracellular Ca2+ concentration ([Ca2+](i)) was monitored in singl e cells isolated from adult rat supraoptic (SO) nuclei. The great majo rity of cells (85%) were neurones and most were immunoreactive to oxyt ocin or to vasopressin (AVP). 2. The resting [Ca2+](i) of the majority (80%) of the neurones remained stable while 20% of the neurones displ ayed spontaneous [Ca2+](i) oscillations which disappeared in low-Ca2(100 nM) EGTA buffer.
