alpha-wave training

a type of neurofeedback training that aims to teach individuals how to achieve a state of peaceful wakefulness and relaxation by increasing alpha-band activity (alpha waves). The technique usually involves alpha neurofeedback (formerly called alpha biofeedback), the process of providing a feedback stimulus (typically an auditory tone) when alpha waves appear over the occipital cortex on a scalp electroencephalogram. The efficacy of such training is disputed. See also alpha state.

rage

rage

n. intense, typically uncontrolled anger. It is usually differentiated from hostility in that it is not necessarily accompanied by destructive actions but rather by excessive expressions. In nonhuman animals, rage appears to be a late stage of aggression when normal deterrents to physical attack, such as submissive signals, are no longer effective. It generally includes rapid respiration; thrusting and jerking of limbs; and clawing, biting, and snarling.
