what is theta,beta,alpha
please answer
Answers
The EEG (electroencephalograph) measures brainwaves of different frequencies within the brain. ... 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).
What are the 4 types of brain waves?
The classic names of these EEG bands are delta, theta, alpha, beta, and gamma. They are measured in cycles per second or hertz (Hz). Delta brainwaves (1-3 Hz) are the slowest, highest amplitude brain waves, and are what we experience when we are asleep.
How do theta waves affect the brain?
Theta brain waves can also occur when you're awake, but in a very deeply relaxed state of mind; a state that some may describe as “autopilot.” However, if you experience high levels of theta waves while you're awake, you might feel a little sluggish or scattered
