Abstract

Specimens of the lizard Ctenosaura pectinata were chronically implanted for polygraphic recordings. Four different vigilance states were observed throughout the nyctohemeral cycle: Active wakefulness (Aw), quiet wakefulness (Qw), quiet sleep (Qs) and active sleep (As). Each state displayed its own behavioral and electrophysiological characteristics. Aw, Qw, Qs and As occupied 5.9%, 25.7%, 67.7% and 0.6% of the 24-h period, respectively. The frequency and the duration of As episodes showed great interanimal variability and the mean duration was very short (12.9 +/- 9 s, mean +/- standard deviation). Stimuli reaction threshold was highest during sleep. It is concluded that the lizard Ctenosaura pectinata exhibits two sleep phases (Qs and As) that may be assimilated to slow wave sleep (SWS) and paradoxical sleep (PS) of birds and mammals.

摘要

对栉尾蜥（Ctenosaura pectinata）的样本进行了长期植入以进行多导记录。在昼夜周期中观察到四种不同的警觉状态：主动觉醒（Aw）、安静觉醒（Qw）、安静睡眠（Qs）和主动睡眠（As）。每种状态都有其自身的行为和电生理特征。Aw、Qw、Qs和As分别占24小时周期的5.9%、25.7%、67.7%和0.6%。As发作的频率和持续时间在不同动物之间表现出很大的变异性，平均持续时间非常短（12.9 +/- 9秒，平均值 +/- 标准差）。睡眠期间刺激反应阈值最高。结论是，栉尾蜥（Ctenosaura pectinata）表现出两个睡眠阶段（Qs和As），这可能类似于鸟类和哺乳动物的慢波睡眠（SWS）和异相睡眠（PS）。
