Alpha Wave
A brain wave with a frequency of between 14 and 50 cycles
per second, related to relaxation and dream states. Through
biofeedback machines, subjects can learn to produce alpha
waves and induce altered states of consciousness. During the
1970s, many thought alpha waves to be especially associated
with ESP and worked on producing them as a means of assisting
people with psychic development. Today, that enthusiasm
has waned.
