| Popis: | The changes underwent by the sleep-wakefulness cycle were studied in 46 Wistar albino rats, separated as three groups which were adapted to 14°, 24° and 30°C and there-after observed under several conditions of steady or varying temperature. A strong and complex influence of the environmental thermal conditions was demonstrated. Paradoxical sleep is reduced at low and very high temperatures whereas arousal increases. Arousal and synchronized sleep are affected by the rate of temperature variation and desynchronized sleep is affected only by the direction of variation. Previous adaptation shifts the range of sleep as a function of the adaptation temperature but also of the actual thermal level. A correlation between control of the sleep-wakefulness cycle and thermoregulation is discussed. |
