[Does hypoxia affect electrophysiologic characteristics of Helix pomatia neurons?]

Most neurons of suboesophageal ganglia are not sensitive to hypoxia (pO2 2-4 mm Hg), the depolarization reaches 4 mV approximately in 5% of investigated cells. Only 2 cells where the hypoxia caused a more significant reaction were identified. In silent neuron V2 the membrane potential decreased by 8-11 mV under hypoxia; in neuron PPa34 a sharp increment of activity with pO2 decrease and a decrement with pO2 increase were registered. Activation of Na-K-pump had no practical effect on expression of hypoxic changes.
