在动物身上，痘痘温度的变化会导致脑电(EEG)频率的变化。鉴于冬眠期间身体和大脑温度的大幅下降，以前归因于某些脑电频率的假定功能不再有效，因为逐渐偏离了原始频率。在目前的综述中，有人提出，即使是人和动物的温和温度变化，如跨越昼夜节律或月经周期的温度变化，或由药物引起的温度变化，也会对脑电频率和相应的功率谱产生显著影响。在体温也发生变化的研究中，相对脑电功率谱的变化可能不是研究中治疗的直接原因，而是对身体或大脑温度影响的结果。然而，这些对EEC功率谱的影响通常被解释为是实验处理的直接结果。
In animals, changes in blain temperature induce a shift in frequencies in the electroenccphalogram (EEG). Given the large decreases in body and brain temperature that occur during hibernation, putative functions that were previously ascribed to certain EEG frequencies are no longer valid because of the progressive shift away from the original frequency. In the present review it is proposed that even moderate temperature changes in humans and animals, such as those across the circadian or menstrual cycle, or induced by drugs, have a significant effect on EEG frequencies and the corresponding power spectrum. Alterations in the relative EEG power spectrum, in studies where body temperature also changes, may not be a direct cause of the treatment under investigation, but a consequence of effects on body or brain temperature. However, these effects on the EEC power spectrum are usually interpreted to result directly from the experimental treatment.
