A
There are beta, alpha, theta and delta waves

Q
What are beta waves?
A
Beta ways are characteristic of normal waking consciousness and REM sleep. Typically these have low amplitude and high-frequency
4
Q
What are alpha waves?
A
Characteristics of a deeply relaxed state. High frequency and slightly larger amplitude than beta
5
Q
What are theta waves?
A
Characteristics of the early stages of sleep. Medium frequency and combined of high and low amplitude
6
Q
