title: Rostrum movements in desynchronized sleep as a prevalent manifestation of dreaming activity in Wistar rats.
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.
