Cerebrum Essay

The reticular formation is essential for maintaining wakefulness and in conjunction with the cerebral cortex is referred to as the reticular activating system (p.450)

The cerebellum (or ‘Little Brain’) is an area located at the back of the brain, positioned underneath the occipital and temporal lobes [Figure 1]. The structure’s main purpose is the fine-tuning of movement, and maintaining posture and balance. The cerebellum is commonly thought of as a motor system, because it is mostly involved in outputting to the movement (motor) system. However, the cerebellum’s purpose is not the creation of motor commands, rather the moderation and adaptation of commands to increase their accuracy. It also uses a surprisingly large amount of neurons relative to its size: although it is only approximately 10% of the brain’s total volume, it accounts for over 50% of the total number of neurons in the

The Temporal lobe located at the bottom of the brain is used to process visual information. In the temporal lobe there is an area for language comprehension and the auditory cortex processes sound. This lobe helps with processes related to recognition and associative memory.

Dopamine limits and selects sensory information from the thalmus. The parietal lobe also deals with movement, along with orientation, recognition, and perception of stimuli. This cortical region is the main sensory area for the sense of touch, major inputs from the skin relay from the thalmus to the parietal lobe. All visual processes are carried out in the occipital lobe (true to its name), and the temporal lobe is associated with perception and recognition of auditory stimuli, memory and speech. The temporal lobe is responsible for deriving meanings for the appropriate retention of visual memories, language comprehension, and emotional association. Together these areas of the brain control the body through the CNS (central nervous system). Every bodily function needed to sustain life is initiated first through these primary sensory areas, making the brain of course the most important muscle in the

The Cerebellum is the part of the brain at the back of the skull in the vertebrates. Its function is to coordinate and regulate muscular activity. The Cerebellum is located behind the top part of the brain stem, it is where the spinal cord meets the brain, the Cerebellum is made of two hemispheres. The Cerebellum receives information from the sensory systems, the spinal cord, and other different parts of the brain, and then it also regulates motor movements. The Cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, and then it results in smooth and balanced muscular

Similarly to Broca, in his studies, Wernicke encountered patients with brain lesions, however, these lesions were located on the posterior areas of the left temporal lobe. Also, while patients could speak, their words were often unrecognizable. This portion of the brain was identified to be responsible for understanding language

The occipital lobe is responsible for all things visual. It is located in the cortex and is responsible for the functions of the visual cortex, which is inside of the occipital lobe. Of all the senses, humans rely primarily on their vision and “have proportionally more visual cortex” (pg. 99). The occipital lobe would play its role while playing the game of cards, being able to see the cards I have been dealt and noticing the mannerisms and gestures of my friends.

Our ability to partisipate in a conversation is made possible using our temporal lobe and the broca's areas of the brain. The broca's area is responsible for our speech production, comprehending language processing these languages, and helping a person to control facial neurons. These bundles of anatomical fibers can be found in the frontal lobe of the cortex. Composed of the pars triangular and the pars operculas; two primary parts. The pars triangular can be located in the broca's area. This part of the brain is believed to help interpret multiple modes of stimulus. the broca's area is where we organize and respond to verbal conducts. The pars opercularis can be found in the broca's area of the brain; supporting only one stimulus mode. Pars opercularis assist with coordinating the organ's used for producing speech and language because it is located near the area's of the brain that are related to our motor skills.

The occipital lobes are located at the back of the brain. They receive and process visual information.

The peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates

“It plays such a vital role in human life that many consider it the essence of life.”(Huffman 70) It contains the frontal lobes, parietal lobes, the occipital lobes and temporal lobes. The Frontal lobes receive signals from the other lobes such as motor control, speech production and other higher functions. The parietal lobes Receive signals for bodily sensations and interpret them. The occipital lobes are responsible for vision. The temporal lobes are responsible for hearing, language, memory and some emotion. All of these parts of the brain conduct essential bodily functions and need to be functioning properly like a

The cerebral Cortex is composed of folded gray matter in the cerebrum of the brain, associated with the higher brain functions, coordinations of sensory information, the ability to learn, being able to obtain memorys, and the expression of individuality. playing an important role in consciousness thin sheet of chells composed of billions of nerve cells and their countless interconnections. Each of the two hemispheres of the cortex is divided into four geographic lobes. Frontal, parietal, occipital, and temporal. The motor functions at the rear of the frontal lobes controls voluntary muscle movements involving planning, control, and execution. The sensory functions, at the front of the parietal lobes processes and makes sense out of the information

First, the part of the brain that is responsible for higher forms of thought such as language, the broca’s area which pertains to the production of speech, located in the frontal lobe, is much needed for communication with my friends. When I first seen my friends it was the broca’s area that allowed me to speak smoothly and fluently to them, and as we sat around the table together eating pizza and playing cards it was this part of the brain that indorsed my friends and I to socialize as it helps everyone talk to one another. The Wernicke’s area that is affiliated with the broca’s area is the part of the brain that helps understand the meaning of words.

The parts of the brain that are involved in the chemical sense of taste are the parietal lobes. The parietal lobe is behind the

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).
