Inside the womb we start out as an egg, but one of the first major structures that begin to form is the brain. The brain itself is a complex structure that leaves much to be learned from it. It controls a person’s entire body function and movements whether it be walking, talking, or even going to the bathroom. What most people do not know is that there are five major structures of the brain. The first of the five is the myelencephalon ( the Medulla). The Myelencephalon (or medulla) is the posterior portion of the brain stem. Not surprisingly then, the medulla is composed largely of tracts carrying signals between the rest of the brain and the body. An interesting part of the myelencephalon from a psychological perspective is the reticular formation. It is a complex network of about 100 tiny nuclei that occupies the central core of the brain stem from the posterior boundary of the myelencephalon to the anterior boundary of the midbrain. It is so named because of its netlike appearance (reticulum means "little net"). Sometimes the reticular formation is referred to as the reticular activating system because parts of it seem to play a role in arousal. The various nuclei of the reticular formation are involved in a variety of functions, however — including sleep, attention (definitely important for language), movement, the maintenance of muscle tone, and various cardiac, circulatory, and respiratory reflexes. Accordingly, referring to this collection of nuclei as a system can be misleading. Generally, the myelencephalon does not play an important role in language production or comprehension.…

Out of all the organs in the human body, the brain is the most intricate and interesting. The brain consists of millions of neurons that work together to help the body function. Furthermore, the brain creates differences between individuals in numerous aspects such as thinking, acting, and learning. Within the novel, Incognito: The Secret Lives of the Brain by David Eagleman, a neuroscientist delves into the ins and outs of the almighty brain. As Eagleman explains the brain himself, “… then there’s your brain. Three pounds of the most complex material we’ve discovered in the universe. This is the mission control center that drives the whole operation, gathering dispatches through small portals in the armored bunker of the skull” (Eagleman, p. 1, 2011).…

There are three major brain divisions. They are the cerebrum, the brainstem, and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions, such as reasoning and rationalizing, among others. The occipital lobe is concerned with vision and processing the information received from the eyes. According to the reading, the “key functions of the parietal lobes include perceiving and integrating sensory and perceptual information,…
In order to respond these questions, further analysis into the brain and cognitive gathering was defensible. "Cognition refers to a diversity of high-level brain tasks; including the capability to learn and remember data; systematize, preparation, and problem-solve; focus, preserve, and move attention as essential; appreciate and use language; precisely perceive the surroundings, and execute calculations " (National Multiple Sclerosis Society, n.d.). The brain has several parts and each part is accountable for a different purpose. The brain composed of the Cerebral Cortex, the Left and Right Hemispheres, the Corpus Callosum, the Frontal Lobe, the Parietal, Occipital, and Temporal Lobes, the Limibic System, and the Basal Ganglia. The Center for Neuro Skills states that, "One of the most universal consequences of frontal damage can be a vivid change in social manners. An individual 's character can undergo momentous changes subsequent to an injury to the frontal lobes, particularly when both lobes are concerned" (Engelfried,…
One brain two sides; the left brain analysis breaking information into parts about 95% of people use the left brain to speak, write, and understand. This includes time sense and rhythm. The right side of the brain processes information by using nonverbal responses such as, pointing at objects, simple language comprehension and recognition of pattern. Lobes of the cerebral cortex are larger fissures on the surface of the cortex. The cerebral cortex is responsible for reasoning planning, mental abiliites, sense of self and motor control. This area contains mirror neurons, which becomes active when you observe someone else and then you carried out the same action.…
Operant conditioning is a method of learning that occurs through rewards and punishments for behavior. When Zane does well at evaluations his mom pays him twenty dollars. Zane will most likely do his best since he knows twenty dollars is on the line. Mental images are mental representations or pictures of objects we create in our mind about the outside world If Zane is shy and gets nervous while performing, he can imagine the people without their pants on. The cerebellum helps control posture, balance, and the coordination of voluntary movements. Without cerebellum Zane would not be able to sit up straight and move his mouth correctly. Your mouth has to be a certain way for you to play the oboe. The frontal lobes are associated with reasoning, planning, parts of speech, movement, emotions, and problem solving. The frontal lobes help control your emotions and nervousness. Often referred to as the "body clock", the…

The biggest part of the brain is cerebrum. The cerebrum is the thinking part of the brain and it controls the voluntary muscles, the ones that move when you want them to. When one is thinking hard, trying to solve a math problem or trying to figure out a video game, one is using the cerebrum. (Kidshealth, n.d.) The cerebrum is made up two sides, the left and right hemispheres. The right half of the cerebrum controls the left side of the body and the left side controls the right side. These two are connected by long neuron branches called the Corpus Callosum. Each hemisphere has four lobes; The frontal lobe is associated with reasoning, planning, movement, emotions and problem solving. The parietal lobe is associated with tactile sensory information such as pressure, touch, and pain. The temporal lobe is associated with the…
It also aids resolution of conflicting thoughts and decision-making as well as anticipate probable outcomes or consequences. Manages social behavior (e.g., morals) and assessment of body sensations and its reactions (e.g., sexual behaviors). This part of the brain also overlooks personality, consciousness and general intelligence which is why people with head trauma may sometimes change behavioral patterns (Paik, 1998). The temporal part of the brain function revolves around hearing and receiving sensory input such as sounds, pitch and…
The only part that is new, is that in order to carry on a conversation, you must be able to think critically when communicating with another person. The mind-body problem comes in to play here. Is your brain doing the thinking for you or is your mind controlling your thoughts? So far, we haven't been able to find a concrete answer yet. However, what we do know is the brain and the rest of the body use neurons to perform millions of tasks everyday that we are generally unaware of. People perform and execute hundreds of thousands of movements every day without even thinking about them. Every time you scratch an itch or say "hello", there are millions of neurons firing off. Neurons are an amazing part of our everyday lives and the key ingredient to navigating our way through the…
