The physiological mechanisms that allow for sleeping in a vertical position, which is primordial for arboreal primates, have not been studied yet.
A non-invasive polysomnographic study of 6 spider monkeys (Ateles geoffroyi) was conducted. The relative beta power of the motor cortex and its linear relation with muscle tone in the facial mentalis muscle and the abductor caudae medialis muscle of the tail during wakefulness and sleep stages were calculated.
A strong negative linear relationship (r = -.8, P = .03) was found between the relative power of the beta2 band in the left motor cortex and abductor caudae medialis muscle tone during delta sleep.
The left motor cortex, through beta2 band activity, interacts with abductor caudae medialis muscle tonicity during delta sleep. This interaction takes part in the mechanisms that regulate the sleep postures.
对于树栖灵长类动物至关重要的垂直睡眠生理机制尚未得到研究。
对6只蜘蛛猴（黑掌蛛猴）进行了非侵入性多导睡眠图研究。计算了清醒和睡眠阶段运动皮层的相对β功率及其与面部颏肌和尾部内侧尾展肌肌张力的线性关系。
在慢波睡眠期间，左运动皮层β2频段的相对功率与内侧尾展肌肌张力之间发现了强烈的负线性关系（r = -0.8，P = 0.03）。
在慢波睡眠期间，左运动皮层通过β2频段活动与内侧尾展肌张力相互作用。这种相互作用参与了调节睡眠姿势的机制。
