The brain is an incredible part of our body and controls everything from body coordination, to thought processes and the regulation of bodily functions. The brain has enough energy to power a 25-watt light bulb. This is power! The brain is composed of the cerebrum (and its lobes), the thalamus, the hypothalamus, the brainstem, and the cerebellum. The brain is made up of; frontal lobe, parietal lobe, temporal lobe and occipital lobe. It is the largest part of the brain and accumulates 85% of the weight. (1) Each part of the brain has its own specific and unique functions. Scientists have and are still studying to unravel the mysteries and full potential of the human brain. The frontal lobe is the most anterior section of the brain. The frontal lobe is associated with reasoning, planning, speech, movement, emotions, and problem solving. (2) The frontal lobe is the last to fully mature, which is why children and adolescents may have difficulty making good decisions and thinking about subsequent consequences. Studies using MRI have shown that most traumatic brain injuries occur in the frontal region of the brain. (5) The frontal lobe is involved in controlling many aspects of our lives, if the frontal lobe were to be damaged there are many possible outcomes. The patient may lose strength in the arms, creating facial expressions becomes more difficult, difficulty speaking, personality may change, and IQ scores may decrease. Scientists have shown that IQ tests can decline because a frontal lobe lesion affects the person's problem-solving skills. (5) The parietal lobe is the most superior part of the brain. The parietal lobe receives and analyzes sensory information from touch, temperature, and pain. (1) The primary sensory part... in the center of the paper... the brain which consists of the corpus callosum, the thalamus and the hypothalamus. The corpus callosum is the only connection between the left and right hemispheres of the brain. The two hemispheres communicate using neurons through the corpus callosum. (1) This allows humans to multitask, such as reading and typing at the same time. The thalamus receives sensory information from the spinal cord and cranial nerves and then transmits the message to the midbrain, which transmits the motor message to the body. An example would be a hand on a hot stove: instantly pain neurons fire in the brain telling the hand to get off the stove. And finally the hypothalamus is part of the endocrine and nervous system. Produces hormones and coordinates with the pons and medulla oblongata to control heart rate, blood pressure, and respiratory rate. (1)
