1. Brainstem slices were taken from mature rats. In the dorsal vagal nucleus (DVNX), membrane potentials (Em) of neurons (DVNs) and glia, as well as extracellular oxygen, K+ and pH (Po2, aKo, pHo), were analysed during metabolic disturbances. 2. Postsynaptic potentials of DVNs, elicited by repetitive electrical stimulation of the solitary tract (TS), led to a secondary glial depolarization of up to 25 mV, a fall in Po2 of up to 150 mmHg, a rise in extracellular aKo of up to 9 mM, and a fall in… CONTINUE READING
