“The human brain enables a person to reason, function intellectually, express personality and mood, and interact with the environment” (Sugerman, 2008, p. 277). Our brain is truly remarkable. Considering how much we still do not know about the brain just goes to show how complex and amazing the brain is. No other organ is like the brain and all other organs would be unable to function without the brain. “The three major divisions of the brain are (1) the forebrain, formed by the two cerebral hemispheres; (2) the midbrain which, includes the corpora quadrigemina and cerebral peduncles; and (3) the hindbrain, which includes the cerebellum, pons, and medulla” (Sugerman, 2008, p. 277). First off the brain stem is made up of the midbrain, medulla and pons, these connect the hemispheres of the brain, cerebellum, and spinal cord (Sugerman, 2008, p. 277). The brain stem is made up of nerve bodies called reticular formation, which is in charge of some of the most vital operations of the body, cardiovascular and respiration functions (Sugerman, 2008, p. 277). These two functions are done involuntarily each day. We do not need to think about breathing every few seconds or make our heart beat constantly. This process keeps us awake also. Different nuclei are responsible for different motor functions accordingly (Sugerman, 2008, p. 278).
“The cerebellum is composed of gray and white matter, and its cortical surface is convoluted like the surface of the cerebrum. It is also divided by a central fissure into two lobes connected by vermis” (Sugerman, 2008, 284). The cerebellum has many functions, it is in charge of reflexes, involuntary fine-tuning of motor control and for maintaining balance and posture through extensive neural connections with the medulla (Sugerman, 2008, 284). The little brain or cerebellum, “receives information from the balance system of the inner ear, sensory nerves, and the auditory and visual systems. It is involved in the coordination of motor movements as well as basic facets of memory and learning, homeostatic control,”.
The diencephalon has four major parts: epithalamus, thalamus, hypothalamus, and subthalamus. The thalamus is in charge of “relaying the cerebral cortex information received from diverse brain regions...Axons from every sensory system (except olfaction) synapse here as the last relay site before the information reaches the cerebral cortex” (Sci.uidaho, n.d., para. 2,3). The thalamus surrounds the third ventricle, it allows many sensations to be perceived (Sugerman, 2008, 283).
The cerebrum is one of the parts of the brain that provides equilibrium when it comes to motor skills and plays a petit role in our concentration and language it also normalize our responses to fear and pleasure, with its appearance as an attached part at the bottom of the brain the cerebrum receives inputs from various parts of the brain and the spinal cord. (Pinel, 2009).
Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise be jerky muscle motions. The medulla controls the elementary functions responsible for life, such as breathing, cardiac rate and kidney functions. The medulla contains numerous of timing mechanisms as well as other interconnections that control swallowing and salivations.
The brain has many different parts to it which help one function through daily life; parts such as the cerebrum which controls voluntary movement and regulates functions such as thinking, speaking and the ability to recall information. The cerebellum controls the balance and coordination and finally the brain stem, which consists of the medulla oblongata and the spinal cord which controls all involuntary functions such as breathing, heart rate and blood pressure. The brain stem is also able to carry out these actions even when someone is asleep. To fully understand how crucial the brain is to survival one must understand the functions of the brain stem.
The brain is the most important organ in the body with our heart. It controls every action, thoughts and regulates our bodily function. It is divided into section, each of them are responsible for various process. Before we can understand dopamine, we must talk about the different parts of the brain. The frontal lobe is the main difference between us and animals. ...
The occipital lobe is very important to us, as it takes information from the eyes and processes it. A common name for it is the “visual cortex”. If the occipital lobe is damaged it can cause blindness. Under this is the cerebellum, in charge of very important daily functions like balance and coordination as well as posture. The brain stem is the most basic part of the brain, as well as the oldest. For as basic as it is, it is key to survival. It controls things like breathing, sleeping and digestion as well as maintaining body temperature. The corpus callosum are fibers that are attached to the left and right sides of the brain. The function of the corpus callosum carries messages to and from each side of the brain. As mentioned earlier the limbic system helps to regulate heart rate and body temperature along with the brain stem. There are two parts of the limbic system the amygdala and the hippocampus. The amygdala which combines hearing and sight, it also helps link emotions with the

Neurobiology is a theory that deals with the brain and your nerves. It determines if you are a left or right brain person. One of the theorists is named Roger Sperry. He was a very big neurobiologist. A disease that deals with this theory is ADD/ADHD.
The brain is the control center of the human body. It sends and receives millions of signals every second, day and night, in the form of hormones, nerve impulses, and chemical messengers. This exchange of information makes us move, eat, sleep, and think.
In many opinions it is thought that the brain and the neurons have less than importance than the heart. However, there is large quantities that people disagree that the brain and neurons are an important factor in our body. One study showed, the brain is the one that control every part of the body. Awhile the neurons travels across a synapse se...
The cerebrum is located at the anterior-most part of the brain and is responsible for the combination of complex sensory and neural functions, as well as the initiation and coordination of voluntary activity in the body. It is the largest brain structure in humans and makes up two-thirds of the total mass of the brain (“Cerebrum Anatomy”, 2015). Its surface, a covering made up of grey matter usually 2-4mm thick, is called the cerebral cortex and is mainly made up of the cell bodies of neurons. The cerebral cortex is responsible for integrating sensory impulses, directing motor activity, and controlling higher intellectual functions. It is also responsible for the state of consciousness, which still remains a mystery to neurologists and the rest of the science community (Swenson, 2007).
It is the most important part of the body, because without a brain, none of us would be alive. In the brain, there are the cerebrum, the cerebellum, and the brain stem. The cerebrum holds memories, controls movement, and does problem solving and thinking. It is the biggest part of your brain. The cerebellum is underneath the cerebrum and controls coordination and balance.
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
The cerebrum is the largest part of the brain. It contains all the tools that are responsible the majority of the brains functions. The cerebrum is split up into four sections: frontal lobe, occiptal lobe and pariental lobe. The cerebrum has two sections the right and the left hemisphere that are connected by axons that send messages to and from one another. The matter in this part is made up of cells that carry signals between the nerve cells and the organs that run through the
The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
In the past few decades we have seen how computers are becoming more and more advance, challenging the abilities of the human brain. We have seen computers doing complex assignments like launching of a rocket or analysis from outer space. But the human brain is responsible for, thought, feelings, creativity, and other qualities that make us humans. So the brain has to be more complex and more complete than any computer. Besides if the brain created the computer, the computer cannot be better than the brain. There are many differences between the human brain and the computer, for example, the capacity to learn new things. Even the most advance computer can never learn like a human does. While we might be able to install new information onto a computer it can never learn new material by itself. Also computers are limited to what they “learn”, depending on the memory left or space in the hard disk not like the human brain which is constantly learning everyday. Computers can neither make judgments on what they are “learning” or disagree with the new material. They must accept into their memory what it’s being programmed onto them. Besides everything that is found in a computer is based on what the human brain has acquired though experience.
