Don displayed Theta Wave.

Explanation:

Let treat the concept "Brainwave Forms".

We'll recall that: The Brain is an organ that coordinates all nervous actions in the Central Nervous System of all vertebrates and some invertebrate animals.

Also, Wave can be defined as a disturbance (oscillation) that travels through a medium, transporting energy from one location to another.

Therefore, Brainwave is said to be formed by rhythmic electrical impulse/charge triggered by masses of neurones, thereby interacting with each other in the Central Nervous System.

It is useful to think of Brainwave form from a state of unconsciousness to being conscious. Like the frequency of wave, Brainwave is also measured in Hertz (Hz).

Here are the following types:

INFRA-LOW BRAINWAVE ( <0.5Hz)

INFRA-LOW brainwaves are slow in natural which makes them difficult to detect. Very few studies have been conducted about them.

DELTA BRAINWAVE ( 0.5Hz - 3Hz)

They are slow, loud resonating brainwaves generated in deepest level of meditation and dreamless sleep. Healing and regeneration of body tissues and cells also occurs in this stage.

THETA BRAINWAVE ( 3Hz-8Hz)

Theta Brainwave occurs in sleep. It is the passage to intuitive learning and memory. In THETA WAVE, we are in a dream, bright and clear imagination and information beyond our normal conscious awareness.

ALPHA WAVE ( 8Hz- 12Hz)

Alpha waves dominate during quietly flowing thoughts. They are also known for mental coordination, calmness and generating body alertness.

BETA WAVE ( 12Hz-38Hz)

Beta waves engage us in our day to day activities. They dominate our normal waking state of consciousness.
