Beta waves are closely associated with mental activity as they are present during normal waking consciousness, problem solving, decision making, and concentration. They are generally associated with active thinking and focus.
Gamma waves are the most desynchronous brain waves, as they have the highest frequency (above 30 Hz) and are associated with cognitive processes such as problem-solving and attention. These waves are not synchronized across the brain and are indicative of high mental activity.
Mental depression is believed to be related to the low activity of one or more neurotransmitters in the brain.Although it is not understood exactly how most SSRIs work, they are designed to increase the level of serotonin in the brain.
An electroencephalogram (EEG) is the most common instrument used to measure brain activity by recording electrical patterns in the brain. EEG is non-invasive and helps in diagnosing conditions like epilepsy, sleep disorders, and brain injuries.
This particular symptom sounds like epilepsy. While during a seizure, most epileptics lack responsiveness and are variably comatose/incoherent, the brain is actually overloaded with a high level of firing between synapses, creating a sort of mental wave that the epileptic cannot handle. However I would suggest conducting more research on this matter. There are a whole range of mental conditions or diseases that result in rapid, high concentration brain activity.
Electroencephalography (EEG) is the most common method used to study the patterns of electrical activity in the brain. EEG measures electrical signals produced by the brain's neurons through electrodes placed on the scalp, allowing researchers to analyze brain activity in different states and conditions.
Most, if not all, mental illness (as opposed to emotional disorders) is caused by chemical imbalances in the brain, or by structural anomalies.

This is a myth. The percentage of the brain used varies between person and activity being performed, but most of the brain is used most of the time.
The main chemical change in the brain during dreams is most simply the electrical activity. As the synapses responsible for visual and auditory stimulation are used during a dream, the electrical energy increases.
Physical is obvious... it's physical activity Mental: it helps you relax and clear your mind Social: Most of the team activity involves a team sport or people to do the activity with
