Alpha Response

Alpha should quickly rise on closing eyes, most prominently at the back of the head (> 50%), then drop down again when the eyes open.

Alpha Speed

Alpha speed is a measure of brain efficiency and correlates with intelligence. Optimal alpha dominant frequency is 10Hz and above.

Front-Back Balance

Optimal brain state: more alpha at the back, especially in EC condition, and more beta in the front. Reversals may correlate with weak executive function.
