Hypothesis-generating for sleep-stage effects on spinal cord perfusion; leaves open relevance to human physiology or disease.
Lenzi et al. (1986) studied Sleep-waking cycle. Desynchronized sleep vs. Synchronized sleep was evaluated on Spinal cord blood flow (ml/min/100g) (p=0.05). Desynchronized sleep in rabbits significantly increased spinal cord blood flow compared to synchronized sleep (34.4 vs 18.9 ml/min/100g, p<0.05) due to decreased vascular resistance.
