The Influence of Increased Nitrogen Tensions on Properties of Identified Neurons in 'Aplysia Californica'.
Abstract
The results of experiments indicate that the passive electrophysiological properties and action potentials of neurons in the abdominal ganglion of Aplysia are unaffected by increases in nitrogen tensions to 10 atmospheres absolute. Since no significantly large or consistent alteration occurred in resting potential, action potential, membrane resistance or time constant, it is concluded that these membrane parameters and their underlying conductance states (for sodium and potassium) are not affected by nitrogen tensions through ten atmospheres. This would indicate that these conductance states are stable and well controlled in these neurons to this degree of pressure. The fact that Aplysia is considered an intertidal animal that has not been reported at depths greater than 200 feet ft. indicates that the authors have only mildly 'stressed' this animal's nervous system by taking it to depths equivalent to some 300 feet of sea water.
