Brainwave bands

The frequency bands used to describe electrical activity in the brain, from delta to gamma. Where one band ends and the next begins is a convention.

14 entries, lowest frequency first. All are labeled Measured.

Delta (Low)Measured0.5 Hz is near the low end of the delta band of brain activity, as recorded by EEG (sensors on the scalp).0.5 Hz
Delta (Mid)Measured2 Hz is in the middle of the delta band of brain activity, as recorded by EEG (sensors on the scalp).2.00 Hz
Delta (High)Measured3.5 Hz is near the top of the delta band of brain activity, as recorded by EEG (sensors on the scalp).3.50 Hz
Theta (Low)Measured4 Hz is the lower edge of the theta band of brain activity, as recorded by EEG (sensors on the scalp).4.00 Hz
Theta (Mid)Measured6 Hz is in the middle of the theta band of brain activity, as recorded by EEG (sensors on the scalp).6.00 Hz
Theta (High)Measured7.5 Hz is near the top of the theta band of brain activity, as recorded by EEG (sensors on the scalp).7.50 Hz
Alpha (Low)Measured8 Hz is the lower edge of the alpha band of brain activity, as recorded by EEG (sensors on the scalp).8.00 Hz
Alpha (Mid)Measured10 Hz is in the middle of the alpha band of brain activity, as recorded by EEG (sensors on the scalp).10.00 Hz
Alpha (High)Measured12 Hz is near the top of the alpha band of brain activity, as recorded by EEG (sensors on the scalp).12.00 Hz
Beta (Low)Measured13 Hz is the edge between the alpha and beta bands of brain activity, as recorded by EEG (sensors on the scalp).13.00 Hz
Beta (Mid)Measured20 Hz is in the middle of the beta band of brain activity, as recorded by EEG (sensors on the scalp).20.00 Hz
Beta (High)Measured30 Hz is the upper edge of the beta band of brain activity, as recorded by EEG (sensors on the scalp).30.00 Hz
Gamma (Low)Measured40 Hz is in the gamma band of brain activity, as recorded by EEG (sensors on the scalp).40.00 Hz
Gamma (High)Measured100 Hz is above the clinical gamma band of brain activity, as recorded by EEG (sensors on the scalp).100.00 Hz
