title: [Impulse activity of hypothalamic neurons during asphyxia].
abstract: In immobilized cats, asphyxia produced biphasic changes of the impulse activity of hypothalamic neurons lasting 3--5 min: a short latency period was followed by an increase of firing rate and then gradual and complete disappearance of the discharges. The inhibition of the impulse activity was similar to that during cathodic depression. On the average, the impulse activity in asphyxia lasted during 171 +/- 14 sec in the posterior nucleus, 138 +/- 10 sec in the lateral nucleus, 144 +/- 10 sec in the ventromedial nucleus and 135 +/- 10 sec in the supraoptic nucleus of the hypothalamus. After renewal of artificial respiration the spike discharges reappeared.
