  • Title: Voluntary alpha control, visually evoked potentials, and peripheral physiological indicants of activation.
    Author: Sadler RR, Eason RG.
    Journal: Percept Mot Skills; 1977 Apr; 44(2):491-6. PubMed ID: 866056.
    Abstract:
    To test the hypothesis that voluntary alpha control is mediated in part through self-induced changes in cortical activation level and bodily arousal, changes in several physiological indicants of such activity were systematically examined as a function of the voluntary enhancement and suppression of scalp-recorded alpha activity. Following per-training, 6 subjects attempted to either produce or suppress alpha with eyes closed while receiving continuous anditory feedback of their alpha levels. The results were interpreted as offering tentative support for the hypothesis.
