[The dynamics of the ion currents in the membrane of an isolated mollusk neuron under the action of high pressure].

The effect of high ambient pressure on the inward and outward currents in the membrane of the snail isolated neuron was studied. A significant inhibition of the inward (sodium) current occurred at 101 ata. No significant modification of the outward (potassium) current was found. The data obtained corroborates the hypothesis of inhibitory effect of high pressure on some membrane structures involved in generation of neuronal activity.
