Damm [24]

The parts of the brain of a living organism which perform each of the functions are listed as follows:

<u>Hypothalamus:</u> it regulates sleep.

<u>Optic nerve:</u> it connects brain and eyes.

<u>Cerebellum:</u> it controls balance.

<u>The frontal lobe:</u> it controls thinking.

<u>The </u><u>brain</u><u> stem:</u> it controls breathing and heart rate.

<u>The nucleus accumbens:</u> it is the pleasure center.

<h3>What is a brain?</h3>

A brain can be defined as an organ of soft-nerve tissue that is found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.

Based on scientific records and information, the two (2) sides of the brain (symmetrical left and right hemispheres) are able to communicate through the corpus callosum.

In conclusion, we can infer and logically deduce that the parts of the brain of a living organism which perform each of the functions are listed as follows:

<u>Hypothalamus:</u> it regulates sleep.

<u>Optic nerve:</u> it connects brain and eyes.

<u>Cerebellum:</u> it controls balance.

<u>The frontal lobe:</u> it controls thinking.

<u>The </u><u>brain</u><u> stem:</u> it controls breathing and heart rate.

<u>The nucleus accumbens:</u> it is the pleasure center.
