I am showing how the brain works. Instead of using a real brain, I am using an electrical circuit board, wires, and switches. This is how a brain works. I am going to show 5 examples of the brain in action. These are the heart, lungs, stomach and muscle/motor skills - and the brain. The picture below shows the circuit board and which parts of the body belong to which numbers. The wires are Neurons. Simply - parts of the body can shut down and start as long as the Brain is active - On.
Diencephalon
The fourth region of the brain is the Diencephalon. The Diencephalon is the size of an apricot. The first part of the Diencephalon is the Thalamus. It processes and translates information. These are sensations, weight regulation and energy. The brain has evolved mechanisms like the blood brain barrier. This only lets come chemicals in and out of the brain.

Brain Stem
The 3rd brain region is the Brain Stem, which is connected to the Cerebellum. The Brain Stem connects to the Spinal Cord. The Brain Stem has Pons which are responsible for sensory information. The Brain Stem has three parts: the Pons, Mid-Brain, and the Medulla. The middle of your brain called the Thalamus sorts data. The Hypothalamus is thermal control.

Cerebellum
Like the Cerebrum, the Cerebellum has Perkinje cells. The Cerebellum sends signals to different parts of the body and brain. The Cerebellum is responsible for coordinating muscle movements and for the body’s posture.

The Cerebrum
The Cerebrum takes up 3/4 of the brains volume. It consists of neurons that transfer information. The Cerebrum controls important senses such as speech, reasoning and learning. Under the Cerebrum is the 2nd most important part of the body - the Cerebellum.
