The EEG alpha rhythm was recorded from 8 isolated canine brains in the absence of orbital contents, drug effect, or pulsatile cerebral blood flow. Abrupt shift to hypoxic perfusion, with maintenance of other perfusion variables, resulted in a loss of alpha coincident with a fall in CMRO2 and rise in oxygen deficit. It is concluded that the alpha rhythm reflects neural electrical activity, and that sources in the eye muscles or in cardiac-induced electromechanical properties of the brain may be rejected.
在没有眶内容物、药物作用或搏动性脑血流的情况下，从8个离体犬脑记录脑电图α节律。在维持其他灌注变量的情况下，突然转变为缺氧灌注，导致α波消失，同时脑氧代谢率（CMRO2）下降和氧亏增加。结论是，α节律反映神经电活动，且眼部肌肉或心脏诱导的脑机电特性来源可被排除。
