Event-related alpha (10 Hz) oscillations in the EEG were measured in cats by means of intracranial electrodes. Simultaneous recordings were made from auditory and visual cortex while auditory and visual stimuli were applied (in separate sessions). Frequency domain analysis of the EEG responses showed marked alpha components only for adequate stimulation (e.g. visual cortex-visual stimulus). This hints at a functional relationship between alpha responses and primary sensory processing.
通过颅内电极在猫身上测量脑电图中与事件相关的α（10赫兹）振荡。在施加听觉和视觉刺激时（在不同的时段），同时从听觉皮层和视觉皮层进行记录。脑电图反应的频域分析表明，仅在适当刺激时（例如视觉皮层 - 视觉刺激）才会出现明显的α成分。这暗示了α反应与初级感觉处理之间的功能关系。
