Summary
Evidence is presented in support of the hypothesis that a basic component underlies the subjective experience of the EEG alpha state. Corrective commands to the oculomotor system, causing movement in extrinsic eye muscles and lens adjustment, suppress occipital alpha. Somatic commands to many muscle groups block or suppress central alpha, hence the absence of such commands may be the precondition for an altered state of consciousness that can be repeatedly demonstrated by alpha feedback.
