THE PARTS OF THE BRAINJose L. Barba

The Four Lobes of the Human BrainTemporal lobeFrontal lobeParietal lobeOccipital lobe

Functions of the Frontal Lobe The Frontal lobe is

what allows a person to control movement, make decisions, plan, and problem solve.

This lobe is found in the primary cortex of the brain where your fine movement controls are.

Cases of Damaged Frontal Lobes On September 13, 1848 a railroad worker named Phineas

Gage suffered from damage to the Frontal Lobe after surviving a devastating accident where an iron rod exploded into his left cheek and into his skull. The long term effects of the damage were extreme due to the fact that his personality completely changed. Gage was once a friendly sociable man but after the accident he became into an antisocial irresponsible lying man. This accident gave researchers the effects of damage to the frontal lobe which are antisocial or criminal behavior with poor judgment. In other words complete personality changes.

Functions of the Parietal Lobe The Parietal Lobe which

is found in the brains primary somato sensory cortex allows the person to have body sensations such as being able to feel pain and touch objects.

Other functions-information processing, speech, visual perception, spatial perception

Functions of the Occipital Lobe The Occipital Lobe is

found in the back region of the cerebral cortex. The occipital lobe happens to be the smallest of all four lobes. This lobe allows the person to have visual processing and be able to recognize colors and shapes.

Functions of the Temporal Lobe The Temporal Lobe is

located on the two sides of the brain and it functions the hearing and advanced vision processing. The lower part of the temporal lobe is in charge of being able to recognize patterns and faces. The upper part of the lobe is what allows a person to hear.

Inner Parts of the Brain

ThalamusHypothalamusPituitary glandPons MedullaCorpus CallosumCerebellumAmygdala

Function of the Thalamus

The Thalamus has several functions. It is mostly responsible for relaying sensory signals to the cerebral cortex but It also regulates consciousness and gives you sleep and alertness.

Functions of the Hypothalamus The Hypothalamus

controls some of the basics of living such as your thirst, hunger, sleep, sex drive, and body temperature.

Functions of the Pituitary Gland The Pituitary Gland is

found in the base of the brain and is a hormone releaser. It stimulates your other glands and controls a variety of your body's functions such as thyroid activity, growth in children, urine and sex hormone production, (testosterone for men and estrogen for women)

Functions of the Pons

The Pons are located directly above the medulla and serves primary as a messenger of the brain. Without the pons the brain would not be able to function properly because messages would not be able to get passed along. REM sleep originates in the pons as well.

Functions of the Medulla

The Medulla is located below the pons and is one of the most important parts of the brain because it does all our involuntary functions of the body such as breathing and regulating blood pressure.

The Corpus Callosum

The Corpus Callosum is a band of nerve fibers that connect the two hemispheres of the brain. Without it the two hemispheres will not be able to communicate with each other. For example, if you cover your left eye and see an image it will be transferred to your right side of the brain but since the right side of the brain has the verbal function you will not be able to say what you saw but you know what it is.

The Cerebellum

The Cerebellum is found on top of the pons and it helps provide smooth coordinated body movements. It also involves the basics of learning and memory.

Damage to the Cerebellum

Damage to the cerebellum will result to involuntary movements of the body, dizziness or vertigo, and uncoordinated movements.

The Amygdala

The Amygdala is where all your emotion and motivation happens. The amygdala triggers emotions like fear, pleasure, and anger. Damage to the amygdala can result in loss of emotion like fear. You can literally be fearless and not know what fear is if you damage that area of your amygdala.
