11. His whole being radiated with the deep mellow alpha wave of a natural endurance athlete. 12. Electroencephalography or EEG shows somewhat more persistent alpha waves of slightly lower frequency than usual. 13. The key word is brain waves _ alpha waves _ and how rhythm relates to that. 14. One rhythm of about 10 cycles per second, the alpha wave , is associated with relaxation. 15. The mature alpha wave , at 10 waves per second, is firmly established by age 3. 16. Berger took a cue from Ukrainian physiologist Lord Adrian, who took a particular interest in alpha waves . 17. Alpha wave intrusion occurs when alpha waves appear with non-REM sleep when delta activity is expected.18. Alpha wave intrusion occurs when alpha waves appear with non-REM sleep when delta activity is expected. 19. The study demonstrated a clear reduction in occipital lobe alpha wave and mu wave rhythms during social interaction. 20. The first such communication took place in the 1960s using EEG to create Morse code using brain alpha waves .
