Alpha waves are neural oscillations in the frequency range of 7.5–12.5 Hz[1] arising from synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans. They are also called Berger's wave in memory of the founder of EEG.<ref>[https://en.wikipedia.org/wiki/Alpha_wave Alpha Wave]</ref> | Alpha waves are neural oscillations in the frequency range of 7.5–12.5 Hz[1] arising from synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans.

This frequency range bridges the gap between our conscious thinking and subconscious mind. In other words, alpha is the frequency range between beta and theta. It helps us calm down when necessary and promotes feelings of deep relaxation. If we become stressed, a phenomenon called alpha blocking may occur which involves excessive beta activity and very little alpha. Essentially the beta waves block out the production of alpha because we become too aroused. | |||
* Frequency range: 8 Hz to 12 Hz (Moderate) | |||
* Too much: Daydreaming, inability to focus, too relaxed | |||
* Too little: Anxiety, high stress, insomnia, OCD | |||
* Optimal: Relaxation | |||
* Increase alpha waves: Alcohol, relaxants, some antidepressants | |||
