Question

Describe the beta and gamma waves formed during the EEG recording.

Answer 1

EEG:

1. An electroencephalogram (EEG) is a recording of brain activity.
2. During this, small sensors are attached to the scalp to pick up the electrical signals produced by the brain.

Beta waves in EEG:

1. It has a frequency in the range of fifteen heartz to thirty heartz.
2. These waves originate from the frontal and parietal regions.
3. Beta activity is related to motor behavior.
4. It weakens in active movement.

Gamma waves:

1. It has a frequency in the range of thirty heartz and hundred heartz.
2. Gamma waves indicate the binding of several neurons together to carry a motor function.
