The human brain has three major components, which are the brain stem, cerebellum, and cerebrum. The brain stem is responsible for connecting the brain to the spinal cord. The brain stem controls breathing, digestion, heart rate and other involuntary processes. The cerebellum is involved in some cognitive functions such as language, attention and emotional functions such as fear or pleasure, but the cerebellum mainly controls balance and motor controls. The cerebrum is split into two different hemispheres – left and right. The cerebrum is protected by the cerebral cortex, which is a protective sheet of neural tissue. The cerebral cortex also protects the thalamus, hypothalamus and pituitary gland. The thalamus receives information from the brain stem and spinal cord and delivers the information to the cerebral cortex. The hypothalamus and pituitary gland control instinctive functions, body temperature and behavioral responses such as feeding, drinking, sexual response, aggression and pleasure. (Mastin, 2010)
Figure 1: Lobes of the Cerebral Cortex
The cerebral cortex is responsible for memory, attention, perceptual awareness, language and thought. The cerebral cortex is divided into four main lobes or regions. The lobes cover both hemispheres. The lobes or regions are the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The frontal lobe is responsible for functions such as decision making, conscious thoughts, and higher mental functions. Located in the frontal lobe is the prefrontal cortex. The prefrontal cortex processes short-term memories and stores long-term memories. If humans make a effort to retain a memory, then the prefrontal cortex will retain the memory, thus making it...

...the night improves human ability to perform spatial task. A full night sleep is essential for learning. Without a full night sleep, learning may or may not occur. NREM sleep is when the brain is about to rest, not all of the brain but most of the brain rest. REM sleep is when the brain is in a deep sleep. (Sceid, 2012)
A vocabulary test consisting of five unusual words will be administered to three groups of students. The treatment group will be exposed to the recording while they are asleep. The control group will not be exposed to the recording. The third group will be exposed to the recording while they are awake. The experiment is over a span of four days. A pretest and posttest will be administered. Both test will look the same and ask the same questions. It is expected that there will be significant difference between the two groups test scores.

- The human brain is divided in two different symmetrical parts, the hemispheres, which are connected by the corpus callosum – this connection enables us to engage in higher cognitive processes (Rogers, Zucca & Vallortigara, 2004). Evolution provided us with the capacity to benefit from lateralization, allowing us to perform well while involved in two completely different tasks simultaneously. Furthermore, the plasticity of the brain makes it easy to thrive in extreme situations, such as having the two hemispheres disconnected or even having one hemisphere removed....

- If the internet is full of so much information, it should come with a caution sign warning people that it may affect and rewire their brains. The internet/Google has been reprogramming the brain without the person actually knowing it. The internet is such a powerful tool that has been controlling people and changing the brain. It has changed the brain to do things differently like thinking and working differently. The internet is negatively affecting the human brain by changing the way people think, the way people read and creating memory problems.... [tags: Brain, Human brain, Traumatic brain injury]

- There are many things we can do to keep our minds from wandering when attempting to complete a particular task. Whether the task be reading, writing, or even driving home from work. However, have we put much attention into how what we consume plays a role in the aptness our brain possesses for information retention. What we regularly choose to consume may be causing unfavorable effects to our brain’s health, test accuracy, and memory retention. We, quite indisputably, eat to live. So, it’s only applicable that what we are eating is influencing our functionality.... [tags: Brain, Nutrition, Human brain, Cerebral cortex]

- In the recent discussions of the Internet and its effect on its users, a controversial issue has been whether or not the Internet usage is affecting our cognitive abilities. On one hand, some argue that the Internet is weakening our capacity for concentration and contemplation. Specifically, Nicholas Carr argues that excessive Internet use is leading to a lack of deep thinking and focus. On the other hand, however, others argue that the Internet combined with human brain power is beneficial rather than harmful.... [tags: Internet, Instant messaging, Brain, Human brain]

- n her Ted Talk Jill Bolte Taylor explained how in human brain right and left hemisphere communicate and how the two sides have completely different purpose. She told her own story how she experienced stroke and lost the function of her left hemisphere and how she lost her verbal ability because of the golf ball size hemorrhage. She also wrote a book called “My stroke of insight” about this experience. It took 8 years for her to recover, which shows the plasticity of the human brain, to make new connections and regain the lost abilities.... [tags: Brain, Human brain, Central nervous system]

- The purpose of this paper to examine the evolution of the human brain that distinguishes them from other species based on the traits that humans possess: such as language, emotional complexity and consciousness. The significance of traits are due to adaptations in humans to promote the survival of our ancestors. Professor Hamilton (2012) discusses that the evolution of the human brain starts with the idea of the Triune brain, proposed by MacLean, whereby the human brain is made up of three parts: Reptilian, Paleo-mammalian, and Neo-mammalian....

- Weighing only 3 pounds, the human brain is the most complex structure known to man. It is what sets humans apart from the rest of the other animals. It is a powerful organ that allows us to learn, store memories, think creatively, and communicate with one and another. Physical damage to any organ in the human body can be detrimental and that is no different with the brain. However, once the brain is damaged, there is often nothing that can be done. Damage to the brain is not only done physically, but a person 's lifestyle, in particular, living in poverty has negative effects to the brain.... [tags: Brain, Nervous system, Neuron, Human brain]

- Introduction This Grand Challenge project is on reverse engineering the brain, and how the technology for human brain implants has developed thus far and how it will advance in the future. Reverse engineering the brain is one of fourteen Grand Challenges, which, if solved, will advance humanity. The ultimate goal of this challenge is to be able to fully simulate a human brain and understand how consciousness, thoughts, personality and free will function [Lipsman, Nir, Glannon, 2012]. As a result, computers will be enhanced, artificial intelligence will be unparalleled, and implants will aid damaged brains.... [tags: Human brain, Brain, Cerebral cortex, Frontal lobe]

- The human brain is the working force for the entire body. It tells people what to say, how to walk, tells or heart to pump, and every other little activity that goes on in the body. Not only does the brain instruct humans, it grows and becomes stronger. It allows humans to think of new information whenever they want. What would people be like without a brain. That answer is dead, like a rock. When a person takes a blow to the head hard enough to move the brain they get a concussion. This injury has been a huge focus point for doctors around the world these past few years, especially with sports.... [tags: Brain, Human brain, Traumatic brain injury]

- The human brain undergoes its most crucial stage of development during adolescence which places it in a very vulnerable position. There are two types of tissues that the brain is composed of: grey matter and white matter. Grey matter serves as the foundation of the brain, for it is comprised of neurons which are responsible for processing information. White matter, on the other hand, refers to the wiring between brain cells which is in charge of circulating this information across the brain. Through further examination of these tissues, neurologists have discovered that the composition of a teenager’s brain is vastly different in comparison to their adult counterpart....
