1. Cortical temperature was measured with subdural thermistors during waking and sleep in eight
Macaca mulatta monkeys. A normal diurnal curve was present, and during the day periods of heightened arousal were associated with temperature increases. During the night periods of restlessness or awakening were associated with temperature increases, the temperature decreasing as the animal returned to sleep.
2.
2. REM sleep was most often associated with decreases in cortical temperature, irrespective of whether the animal entered REM sleep from non-REM sleep or from waking. In general, thermistors posterior to the central sulcus or over temporal cortex recorded statistically significant temperature decreases during REM sleep, whereas thermistors over frontal cortex recorded either significant decreases or no significant change with REM. No recording sites showed significant temperature increases during REM sleep.
3.
3. It is suggested that these results represent increased cortical blood flow during REM sleep, and that cortical blood flow during REM sleep may exceed flow during non-REM sleep, quiet waking or intense arousal.

1. La température corticale est mesurée avec des “thermistors” sous-duraux pendant l'éveil et le sommeil chez huit
Macaca mulatta. Une courbe diurne normale est présente, et pendant le jour des périodes d'“arousal” élevé sont associées avec des élévations de la température. Pendant la nuit des périodes d'insomnie ou d'éveil sont associées avec des élévations de température, la température diminuant comme l'animal retourne au sommeil.
2.
2. Le sommeil REM est le plus souvent associé avec les dimunutions de al température corticale, sans rapport avec le fait que l'animal entre dans le sommeil REM depuis le sommeil non-REM ou depuis l'éveil. En général, les “thermistors” postérieurs au sulcus central ou sur le cortex temporal enregistrent des diminutions de température statistiquement significatives pendant le sommeil REM, tandis que les “thermistors” sur le cortex frontal enregistrent aussi bien des diminutions significatives ou aucune variation significative avec REM. Aucun site ne montrent d'élévation significative de température pendant le sommeil REM.
3.
3. Les auteurs suggèrent que ces résultats représentent l'augmentation du flot sanguin cérébral durant le sommeil REM, et que le flux sanguin cortical pendant le sommeil REM peut excéder le flux pendant le sommeil non-REM, l'éveil tranquille ou l'arousal élevé. |
