The conversation between human and AI assistant.
How do lectures affect the relative ratio of brain waves (alpha/beta/gamma/theta/delta)?
Yes, please do.
Lecture can increase the alpha and gamma waves, indicating increased focus and alertness, respectively. Beta waves can also increase, which indicate active thinking, but they may decrease if the lecture is repetitive or boring. Theta waves, which indicate relaxation and drowsiness, may also increase during a lecture. Delta waves, which indicate deep sleep, are unlikely to be affected unless the listener actually falls asleep during the lecture.
