Discharge pattern of single neuronal units in cortical projection area of vagus nerve during successive episodes of hypoxia.
For an analysis of discharge pattern of single neuronal units in the cortical projection area of the vagus nerve during successive episodes of hypoxia their action potentials were recorded extracellularly. Changes in the discharge pattern were assessed by means of histograms of interimpulse intervals. It was found that the reaction of neurons to repeated exposure to hypoxia includes: a) increased frequency of discharges, b) decreased activity, or c) habituation, i.e. reduction in the degree of neuronal activity changes during successive exposures to hypoxia.
