Introduction

The brain is your body’s control center. Our thoughts, actions, and memories, among many other processes are controlled by our brains. The brain is composed of four lobes, the temporal lobe, occipital lobe, parietal lobe, and frontal lobe. Each lobe plays a vital role in helping our bodies to function. Although all lobes of the brains serve a purpose, this paper will be analyzing the frontal lobes purpose by looking at its location, functions, and manifestations that occur when it malfunctions.
Frontal Lobe Description/Location

The front of our brain, which is called the frontal lobe, is located just behind …show more content…

The motor cortex on each side of the brain controls muscles on the opposite side of the body (Sherwood, 2006). While the motor cortex allows us to initiate movement, the premotor cortex selects which movements should be performed (Kolb & Whishaw, 2009). Any complex or coordinated movement is processed by the premotor cortex The premotor cortex allows us to process motor information and is responsible for coordinating learned, skilled motor activities, such as riding a bike, or playing an instrument (McKinley & O’Loughlin, …show more content…

Fine movements, speed, and limb strength can all be effected from damage to the primary motor cortex (Kolb & Whishaw, 2009). We depend on our fingers to carry out fine motor movements. The hands are represented in a larger area of the cortex than the trunk, because the hand muscles perform more detailed movements than the trunk muscles, so more motor activity is devoted to our hands due to the need to manipulate our environment (McKinley & O’Loughlin, 2008). A frontal lobe injury in the primary motor cortex can cause a loss of speed and strength in hands and limb movements in the contralateral limbs (Kolb & Whishaw, 2009). When the frontal eye fields become damaged in the frontal lobe saccadic eye movements are effected. Patients with frontal eye field damage struggle to create eye movements towards a target stimulus (Kolb & Whishaw, 2009). This causes a loss of oculomotor

    may also be affected in deleterious ways. They can have blurred vision, decreased sensation of limbs, unable to locate them without looking, decreased sense of taste, ringing of the ears etc. 2. What is the difference between a '' and a ''? Two ideas about the nervous system that can be better understood from these observations are the concepts of having and locating the I-function. It seems that the I-function here is very often affected in terms of voluntary movement.

    Prefrontal Cortex The prefrontal cortex is the most anterior portion of the frontal lobe. It responds mostly to stimuli signaling the need for movement, however it is also responsible for many other specialized functions. It receives information from all sensory systems and can integrate a large amount of information (Kalat 2004). Studies have shown that the prefrontal cortex is responsible for working memory. Working memory is defined as "the information that is currently available in memory for working on a problem" (Anderson 2005).

  • Essay On The Nervous System

    962 Words  | 2 Pages

    The nervous system includes the brain and spinal cord of the central nervous system and the ganglia of the peripheral nervous system. The functional unit of the nervous system is a neuron. It is estimated 100 billion neurons reside in the brain with some neurons making anywhere between 10,000 to 100,000 connections with other cells! A distinctive class of neurons, mirror neurons discharge both when the individual executes a motor action and when he/she observes another individual performing that same or similar action. These mirror neurons were discovered by neurophysiologists in the 1990s at the University of Parma, Italy. Using macaque monkeys, these researchers found that neurons of the rostral part of the inferior premotor cortex were activated both when the monkey made goal-directed hand movements (grasping, holding, & tearing) and when the monkey observed specific hand movements done by the experimenters (Pellegrino, et al., 1992). In a monkey’s inferior frontal and inferior parietal cortex, it is estimated that about 10% of neurons have “mirror” properties.

    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

    Although the brain only weighs about three pounds, it is a very powerful and essential organ in the body (Brain Structures and Their Functions). The cerebrum, cerebellum, and the brain stem are the three main parts of the brain. The cerebrum fills up most of the skull, its main functions are for remembering, problem solving, thinking, and feeling (Bellamy 23). It also controls movement throughout the body. The cerebellum is located towards the back of the head. It controls mostly just coordination and balance (Brain Structures and Their Functions). The brain stem is underneath the cerebrum and in front of your cerebellum. It attaches the brain to the spinal cord and controls functions like breathing, digestion, heart rate and blood pressure (Carter 12). The brain is also divided into halves. The left side of the brain controls the right side of the body, while the right side of the brain, controls the left side of the body (Bellamy 17).

  • Case Study: Laila's Brain

    1367 Words  | 3 Pages

    First, the planned action of walking allows Laila to move in order to get to her desired spot. Through this planned action, Laila walks towards her friends and the pizza with assistance from her motor system. Laila’s brainstem and cerebellum, specifically, are responsible for controlling involuntary movement. Her lower areas in the brain such as the brainstem and cerebellum typically control involuntary movements. Areas that are anatomically higher areas in the brain, control voluntary movements, such as Laila’s cortex. These voluntary movements require Laila is capable of planning and executing the various actions she wants to make. Laila is able to utilize her planning system through association areas of the motor cortex. These areas help with general motor acts. For instance, Laila wants to have the pizza, and her premotor areas, anterior to the motor cortex, are involved in planning to walk towards the pizza. Laila’s ability to walk to the pizza required working premotor areas in her frontal lobe. The areas that plan actions for Laila involve input from the environment in order to initiate a motor plan. Laila’s premotor areas receive input from prefrontal areas and her parietal lobe. These areas deal with motor intention and tactile and visual signals, respectively. The premotor areas also help to

  • Understanding the Brain: The Case of Phineas Cage

    1954 Words  | 4 Pages

    In 1948 Phineas Gage, an American railroad construction foreman, was involved in a terrible accident during which a tamping iron was explosively forced upwards through his left cheek and exiting the top of his head (Harlow, 1948). He stunned his colleagues by not only surviving the event and swiftly regaining consciousness but by also by walking to a nearby cart. Gage regained many of his physical and mental abilities but remained altered in his personality to the extent that he was considered “gross, profane, coarse and vulgar” (Bigelow, 1851), having previously been considered diligent and pleasant. The curious case of this gentleman with extensive brain damage but nevertheless much retained function has fueled interest and research into the localization of function within the brain. Although the exact nature of Gage’s injuries has been subject to extensive debate (Ratiu et al., 2004), it is generally accepted that a large part of his left prefrontal cortex was damaged, including the medial and lateral orbito-frontal and the dorsolateral prefrontal regions.

    Most of the body’s functions such as, thinking, emotions, memories and so forth are controlled by the brain. It serves as a central nervous system in the human body. The mind is the intellect/consciousness that originates in the human brain and manifests itself in emotions, thoughts, perceptions and so forth. This means that the brain is the key interpreter of the mind’s content. Jackson and Nagel seem to resist identifying what we call “mental events” with brain events, for different reasons, while J.J.C. Smart takes the opposing view.

    The human brain is the control center of the human body. It is the most important part of the body, because without a brain, none of us would be alive. In the brain, there are the cerebrum, the cerebellum, and the brain stem. The cerebrum holds memories, controls movement, and does problem solving and thinking. It is the biggest part of your brain. The cerebellum is underneath the cerebrum; it controls coordination and balance. The brain stem is the part closest to the neck. It controls breathing, heart rate, blood pressure, digestion, etc. (Alzheimer's Assosiation, 2011). The brain has two hemispheres as well as the three major sections; the right hemisphere and the left hemisphere. There is not exactly a “music area” in the brain.
