Abstract

Considering that eye movements express visual dreams in humans and are prominent during desynchronized sleep in cats, monkeys and birds, rostrum movements were investigated in a macrosmatic species, the rat, to assess the hypothesis that, expressing olfactory and tactile (involving the vibrissae) dreams, they would prevail over eye movements. Desynchronized sleep episodes lasted 148.8 +/- 12.4 s, rostrum movements lasted 80.7 +/- 6.9 s and eye movements occurred during 40.4 +/- 3.9 s, all in accordance with the original hypothesis.

摘要

鉴于眼球运动能表达人类的视觉梦境，且在猫、猴子和鸟类的去同步化睡眠中很显著，我们在嗅觉灵敏的大鼠这一物种中研究了吻部运动，以评估以下假设：吻部运动表达嗅觉和触觉（涉及触须）梦境，会比眼球运动更常见。去同步化睡眠阶段持续148.8±12.4秒，吻部运动持续80.7±6.9秒，眼球运动发生在40.4±3.9秒期间，所有这些都符合最初的假设。
