The human brain is not only one of the most important organs in the human body; it is also the most complex(www.verywell.com/the-anatomy-of-the-brain-2794895).
Anatomically the brain is divided into three major parts; cerebrum, cerebellum and brainstem[1]. The cerebrum consists of two hemispheres, such as right and left hemispheres. The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. The left hemisphere regulates language and speech, and the right hemisphere controls nonverbal, spatial skills. If the right side of the brain is damaged, movement of the left arm and leg, vision on the left, and/or hearing in the left ear may be affected. Injury to the left side of the brain affects speech

The cerebral cortex is the outermost portion that can be divided into the four lobes of the brain which are known as The frontal lobe, parietal lobe, occipital lobe, and temporal lobe have been associated with different functions ranging from reasoning to auditory perception. Each bump on the surface of the brain is known as a gyrus, while each groove is known as a sulcus. The cerebrum is the largest and most important part of the human brain and is generally associated with brain functions related to thoughts, movements, emotions and motor functions. The outermost layer of the cerebrum is made up of neural tissues known as the cerebral cortex. The cerebral cortex is the part of the brain that functions to make human beings unique. Distinctly human traits including higher thought, language and human consciousness as well as the ability to think, reason and imagine all originate in the cerebral cortex.
The cerebrum consists of two hemispheres, such as right and left hemispheres.
The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. The left hemisphere regulates language and speech, and the right hemisphere controls nonverbal, spatial skills. If the right side of the brain

• The occipital lobe is located at the back portion of the brain and is associated with interpreting visual stimuli and information. The primary visual cortex, which receives and interprets information from the retinas of the eyes, is located in the occipital lobe. Damage to this lobe can cause visual problems such as difficulty recognizing objects, an inability to identify colors, and trouble recognizing words.
The brainstem is located at the bottom of the brain and connects the cerebrum to the spinal cord. The brainstem is like a hard drive of a computer and it is the main control panel of the body. It controls vital functions of the body, including breathing, consciousness, movements of the eyes and mouth, and the relaying of sensory messages (pain, heat, noise etc), heartbeat, blood pressure and hunger. The brain stem is comprised of the hindbrain and midbrain. The hindbrain contains structures including medulla, the pons and the reticular formation.
• The Hindbrain is the structure that connects the spinal cord to the brain.
– The medulla is located directly above the spinal cord and controls many vital autonomic functions such as heart rate, breathing and blood
It sends information for sleep, hearing, taste, and even eye movement. Corpus Callosum: The corpus callosum connects both hemispheres of the brain and allows them to relay messages between one another. People who have a severed corpus callosum can essentially function as 2 different people at the same time, with the left half of their body performing one task, and the right half another. Frontal Lobe: As the largest lobe in our brain, this lobe play a significant role in personality and impulse control.
Forebrain #3 The section I chose is the forebrain which controls the higher functions of the brain, such as thinking, decision making, and dreaming. I chose forebrain #3 which consists of the occipital lobes, parietal lobes, and the somatosensory cortex. The occipital lobes is the visual processing center of the brain containing most of the region of the visual cortex. The occipital lobes are involved in many functions including visual perception, color recognition, reading, comprehension, depth perception, and recognition of object movement.
Firstly, the human brain is a complex organ that commands a variety of different functions within the human body. One specific function of the human
While the brain has three main parts, the cerebrum, the cerebellum, and the brain stem. 2. Peripheral nervous system (PNS) PNS include Cranial Nerves and spinal Nerves. It is communication line between the CNS and the rest of the body.
Forty Studies That Changed Psychology by Roger R. Hock, Seventh Edition reading 1: one brain or two Michael S. Gazzaniga conducted this study in 1967. Gazzaniga wanted to examine to what extent the two hemispheres of the brain could function independently. By severing the corpus callosum the two halves of the brain have an inharmonious relationship. The patients used in the studies were people who suffered from rare cases of epilepsy and seizures. After the patients, brains had been split they took a series of tests designed examine each ability of the brain.
The right side of the brain shows emotion and living in the present. As a man who follows a murderer to his house
The medulla oblongata is located between the pons and spinal cord. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. The midbrain is involved in functions such as vision, hearing, eye movement, and body movement. The pons are involved in motor control and sensory analysis. For example, information from the ear first enters the brain in the pons.
The brain is the most complex and magnificent organ of the human body. It controls the muscle movements, the secretions of glands,breathing and internal temperature. Every creative thought, feeling, and plan is developed by the brain. The brain acts as the body’s control center. The human brain can be divided into the forebrain, mid-brain and hind-brain.
It occupies the front and top portions of the skull, performing sensory functions, motor functions and integration functions such as mental activities. The cerebrum is divided into the right and left sides, or hemispheres. Depending on the area of the cerebrum and which side is affected by a strokes, different functions can be impaired. John Hopkins Medicine (2015) defines the effects that a stroke can have on the left side of the cerebrum as being “left-sided weakness or paralysis and sensory impairment, left neglect which is when a patient denies their paralysis or impairment, inability to see the left visual field of each eye, spatial problems with depth perception or directions, such as up or down and front or back, inability to localize or recognize body parts, inability to understand maps and find objects, such as clothing or toiletry items, memory problems, behavioural changes, such as lack of concern about situations, impulsivity, inappropriateness, and depression”. A stroke that occurs on the right side of the cerebrum, can cause impairments in areas such as (John Hopkins Medicine, 2015) paralysis, sensory impairment and weakness in the right side of the body, language difficulties, inability to see in the right visual field of each eye, impaired ability to do math or to organize, reason, and analyse items, behavioural changes, such as depression, cautiousness, and
Parts of the brain and their functions: the frontal brain with controls the higher mental processes. The midbrain, which controls emotions, motivations and the limbic system. The hindbrain which controls movement, and lower mental functions. 3. Split brain: when the corpus callosum is split it destroys the connection between the left and right side of the brain.
What is the Mind? Introduction To try and explore the ‘mind’ it is necessary to examine if the mind and the brain are separate or if the mind and body are distinct from one another? Is the mind and body separate substance or elements of the same substance? Is consciousness the result of the mechanisms of the brain, wholly separate from the brain or inextricably linked?
The article “Psychiatric Disorders and Functional Disability in Outpatients with Traumatic Brain Injuries” published by the American Journal of Psychiatry studies people who have gone through brain trauma surgery. The main objective of the study is to see what disorders and disabilities come along through the recovery process. After evaluating fifty outpatient brain trauma surgery survivors the results came back and were shocking. “Thirteen (26%) of the patients had current major depression, and an additional 14 (28%) reported a first-onset major depressive episode after the injury that had resolved.
The human brain can be considered the most important thing for an individual to correctly function.
Are you good at math, science, engineering, or technology? If you said yes, chances are you have mastered L-directed thinking; the more analytical skills your brain posses. However, what happens to our R-directed thinking skills? Although we use both sides of our brain while executing tasks, certain skills are more active in one hemisphere than another. Creativity, empathy, and laughter, are all skills dominated by the right side of our brain.
This suggestion works in accordance to the evidence that suggests that the brain is predisposed to have certain areas specifically designed for language processing and development. For example, Gazzaniga (1986) stated that language processing occurs in the left hemisphere of the
