High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! Beta wave, or beta rhythm, is the term used to designate the frequency range of brain activity between 12 and 30 Hz (12 to 30 transitions or cycles per second). Beta waves are split into three sections: High Beta Waves (19Hz+); Beta Waves (15-18Hz); and Low Beta Waves (12-15Hz). Beta states are the states associated with normal waking consciousness. Low amplitude beta waves with multiple and varying frequencies are often associated with active, busy, or anxious thinking and active concentration. Over the…mehr

High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! Beta wave, or beta rhythm, is the term used to designate the frequency range of brain activity between 12 and 30 Hz (12 to 30 transitions or cycles per second). Beta waves are split into three sections: High Beta Waves (19Hz+); Beta Waves (15-18Hz); and Low Beta Waves (12-15Hz). Beta states are the states associated with normal waking consciousness. Low amplitude beta waves with multiple and varying frequencies are often associated with active, busy, or anxious thinking and active concentration. Over the motor cortex beta waves are associated with the muscle contractions that happen in isotonic movements and are suppressed prior to and during movement changes. Bursts of beta activity are associated with a strengthening of sensory feedback in static motor control and reduced when there is movement change. Beta activity is increased when movement has to be resisted or voluntarily suppressed.
