  • Prefrontal Cortex

    1160 Words  | 5 Pages

    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

  • The Temporal Cortex

    The Temporal Cortex The temporal cortex, also known as the temporal lobes, is the part of the verbal cortex in the left and right hemispheres of the brain lying inside the temples. In general the temporal lobes handle a wide variety of task that are essential to every day functioning. Patient him/herself The temporal lobes are readily recognizable brain structures with a thumb like appearance when viewed from the side. Their name reflects their location beneath the temporal bone

  • Orbitofrontal Cortex Analysis

    1887 Words  | 8 Pages

    Introduction The orbitofrontal cortex is found to be associated with the processing of cognitive information related to decision making. This is, responding to the reward or punishment outcomes experienced by an individual after making a decision and, responding to the expectation of facing such an outcome later. This region of the brain is involved in the regulation of emotions during the process of decision making thereby causing an individual to engage in certain social behaviours. This essay

  • Lesions of the Prefrontal Cortex

    1521 Words  | 7 Pages

    Lesions of the Prefrontal Cortex The prefrontal cortex is involved in a wide variety of functions. It is known as the area of the brain which has “executive control”, taking input from other areas of the brain and combining and applying those functions (Kalat 2004). Lesions to the prefrontal area can greatly impair overt behavior of an inflicted individual. These deficits are dependent upon the severity of the lesion and the specific region of the prefrontal cortex in which the lesion resides

  • The Prefrontal Cortex and Decision-Making

    at the most basic level of self-regulation” (p. 266). Through my chosen articles I found that the Prefrontal Cortex is the major portion of the brain that is responsible for decision-making. To understand the decision-making process better the prefrontal Cortex can be divided into three regions: the Orbitofrontal Cortex, the Anterior Cingulate Cortex, and the Dorsolateral Prefrontal Cortex. Each of these areas contributes to different decision-making sub-processes, which in turn make up the distinctive

  • Prefrontal Cortex Lesions from Neurosurgeon and Patient Perspective

    2784 Words  | 12 Pages

    Prefrontal Cortex Lesions from Neurosurgeon and Patient Perspective In this paper, I will discuss lesions of the prefrontal cortex from the perspective of the practice of neurosurgery (in particular, the sub-field of psychosurgery) and then I will consider some studies that look at the implications of lesions to the prefrontal cortex to the brain and behavior, from the perspective of the patient with the lesion. Initially, I will start with the history and explanation of psychosurgery.

    nervous system (the brain and spinal cord) and peripheral nervous system with two subsystems (the vegetativ and the autonomic nervous system, which controls internal organs function). Information processing occurs hierarchicaly from the cerebral cortex to the spinal cord and peripheral nervous system By stady animal brains and human embryos we can get near insign into the brain growth during fetal life. In the early stages of development the disk, cell plate in the middle of the embryo grows

    worse. There are neural connections from different part of retina to particular region of visual cortex. When the patient suffers from certain ocular disease, visual cortex will alter the connection in order to adapt the visual impairment. Formation of preferred retinal locus Fovea contains numerous of cone cells and it is essential for resolution of image and generating nerve impulse to visual cortex. When the fovea is damaged because of macular diseases, vision will be influenced a lot. In the

  • The Controller of Humans: The Brain

    753 Words  | 4 Pages

    The human brain is composed of many important parts of everyday life. The exterior part of the brain has 9 part in which include are divided into different sections, lobes, cortex, and areas. Within the lobes, it includes frontal, parietal, occipital, and temporal lobes. In cortexes, it has the motor cortex, and the sensory cortex. Within the areas section it includes Broca’s Area. The cerebellum is a small version of the brain, and the cerebrum is the like the whole brain. Although the brain is about

    mesencephalon (midbrain) and the rhombencephalon (hindbrain). Before birth the hindbrain and forebrain divide in each 2 extensions. The central nervous system consists of the brain and spinal cord. The outer part of the brain called the cerebral cortex. This part of the brain is responsible for the functioning of cognition, sensation, motor skills, and emotions. The five main sections of the brain Myelencephalon (medulla oblongata with reticular formation (ARAS), which play a role in activation
