title: Evoked EEG alpha oscillations in the cat brain--a correlate of primary sensory processing?
abstract: 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.
