Functions Of The Various Cerebral Cortex Regions Essay

Throughout history, a human being was always reliant on the primary sensory areas. An ability to communicate and contract languages is considered to be a unique ability of human nation as no other species show an equal amount of complexity in terms of the structure and sound combination. On the other hand, primary visual cortex provides a skill set in order to identify the objects presented in the world, the distance towards them as well as to design a set of actions in order to incorporate some items such as a stone or a pen. The understanding of these systems is crucial, especially for those who suffer from strokes and tumors and as a result lost the ability to visually recognize objects or hear other people. This work will focus of the structure

| The primary communication link between the left and right cerebral hemispheres is called:1. the hypothalamus.2. the hippocampus.3. Broca's area.4. the corpus callosum.

The right side of the brain is responsible for putting information together eg. information recived from eyes-if you see a flower information goes from eyes to the right side of your brain , firing neurons, putting information together so you are able to say "I can see a flower".The left side of the brain analyses information which is collected by the right side of the brain. It

The largest part of the brain "the cerebrum" is divided in to two hemispheres, each hemisphere have different functions and responsibilities in memory, reasoning and language. The two hemispheres are in close communication with each other via corpus callosum .

* First, studies have shown that aspects of experience can sculpt features of brain structure.

Creating the world's first Z-Bomb, would have to be the most dangerous thing that could happen to humans. Turning them into Zombies, it would entirely change the characteristics of a human being and its brain. Although both living, Zombies have drastic defects towards certain aspects of the body. This Z-bomb won’t necessarily turn humans into zombies, but rather give humans zombie-ish characteristics.

The brain stem or the medulla is the closest to the spinal cord. The brainstem is responsible for most of the human bodily functions. The brain stem is critical for human survival and normal human functions. The brain stem is also responsible for information of pain and touch from the head and neck; it is also responsible for the inputs from the face and the mouth. Reticular formation is a group of neurons, nuclei, that are important for sleep and wakefulness. In reticular formation there is nuclei that are a major source of neurotransmitter serotonin. Serotonin is important for regulating mood and activities.

Let’s begin by discussing the parts and function of our brains. The neo cortex is the largest part of the brain and the most important. This part of the brain is divided into four different sections: the temporal lobe, occipital lobe, parietal and the frontal lobe. These four sections are located on either the right or left hemisphere of the brain they are connected by axons that send messages to and fro between both hemispheres and to specific parts of the brain then to the body. Our neo cortex is what makes us so different from our primate cousins.

The connectionist model describes the different areas of the brain and how they process particular types of information (Brookshire & McNeil, 2015). We have a greater understanding of left hemispheric damage. For example, if an individual has damage to their posterior-inferior third frontal gyrus of the left hemisphere, they will present with Broca’s aphasia, which evidences as motor planning deficits. While scientists and researchers have a general understanding of what the right hemisphere is responsible for, we have yet to understand specific areas precise responsibilities. Generally, we recognize the right hemisphere is responsible for behavior and cognition, perception, recognition and expression, attention, and pragmatic communication (Brookshire &

The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.

The cerebrum makes up three quarters of the brain. In the cerebrum, there is the ability to problem solve, move, think and feel (“Alzheimer’s Disease,”n.d.). The cerebrum can be divided into two halves, the right hemisphere and the left hemisphere. Each hemisphere has four lobes, occipital lobe, parietal lobe, temporal lobe, and frontal lobe. Each lobe has specific tasks. For example, the occipital lobe is responsible for visual images.

The personality trait anxiousness seems to have a genetic component, because individuals with that have different biological and behavioral variations of the serotonin-transporter-linked-promotor region (5HTTLPR) genotypes indicate that it’s the cause of differential biological stress reactivity. “Susceptibility to stress may have biological roots, especially in the serotonergic system” (Petersen). Different people becoming anxious and reacting to stress differently because of a genotype shows that there’s a strong nature component. One of the parts of the brain that anxiousness can affect is the amygdala, which signals aggression and fear. “Cognitively changing the meaning of emotional stimuli effects evoked responses in the amygdala and other brain areas” (Mocaiber). So trait-anxious individuals sometimes unconsciously change the meaning of a stimulus to an anxious context. Not only are they succeptible to making stimuli a threat, Mocaiber also claims that they can be “abnormally sensitive to threat-related stimuli.” This makes sense that anxious people see more things as threats and can spot an actual threat very easily.

You live and you learn, from the moment that we breathe our first breath, we are assimilating and are acquiring information. Life changing and profound learning experiences happen before we can even speak, as children our learning process is grandiose. Harvard University published a series of summaries on Child development. One of these articles mentions that “The basic architecture of the brain is constructed through an ongoing process that begins before birth and continues into adulthood.” ("InBrief: The Science of Early Childhood Development," n.d.).

The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).
