Theta

Theta ( θ ) activity: Electromagnetic waves ranging between 4 and 7 Hz in frequency, with an amplitude of less than 30 μV. This activity primarily occurs in the parietal and temporal regions of the brain.

Such waves are produced when people experience emotional pressure, interruptions of consciousness, or deep physical relaxation

Theta Findings

Subjective scores of emotional experience significantly correlated with theta, whereas scores of internalized attention with both theta and alpha lower synchronization.
