Beta activity is generally associated wave forms that are: electrodes are attached to the subjects" scalp to record electrical activity of the brain. The ampli er records an irregular at an amplitude of 13-30 hz. electroencephalogram (eeg) Beta activity is desynchronous; it"s a reflection of different: electrodes are also attached to the subjects" chin to record muscle activity recorded as an electromyogram (emg) neural circuits actively processing information at the same time. Brain activity when we"re are awake and at rest: electrodes placed around the eyes monitor eye movements recorded as an electrooculogram (eog) Brain activity when we"re awake and at rest: When we are awake, our eeg shows two basic patterns: After about 10 minutes, the eeg becomes irregular with mixture of: beta activity is generally associated wave forms that are irregular at an amplitude of 13-30 hz.
