Detailed explanation-1: -The raw EEG has usually been described in terms of frequency bands: Gamma greater than 30(Hz) BETA (13-30Hz), ALPHA (8-12 Hz), THETA (4-8 Hz), and DELTA(less than 4 Hz). For example: Our brain uses 13Hz (high alpha or low beta) for “active” intelligence.
Detailed explanation-2: -There are four main types of brain waves: alpha, beta, delta, and theta. Each one is associated with a different state of mind. This article will take a closer look at how each type of brain wave affects your body.
Detailed explanation-3: -The frequency of beta waves ranges from 15 to 40 cycles a second. Beta waves are characteristics of a strongly engaged mind. A person in active conversation would be in beta. A debater would be in high beta.
Detailed explanation-4: -The brain waves recorded by the EEG are measured in frequency (how many brain waves per second) and in amplitude (the electrical potential or how many cells fire at the same time at the same speed is expressed as voltage).
