[Impulse activity of the nodose ganglion neurons in myocardial ischemia].

Standard microelectrode techniques were used to study the impulse activity of different types of nodosal ganglion neurons in the course of the development of myocardial ischemia. The cardiopulmonary late inspiratory and inspiratory-expiratory neuronal responses were estimated upon ligation of the coronary artery during the first respiratory cycle after blood flow stoppage. Spontaneous activity of cardiopulmonary neurons was not dependent on coronary circulation disturbances at the moment of coronary artery ligation. Later on, however, during the development of myocardial ischemia, there occurred substantial changes in all the types of nodosal ganglion neuronal activity, excluding real inspiratory neurons.
