Explain one study related to localization of function in the brain. Introduction State what you are doing in the essay This essay will attempt to give a detailed account including reasons or causes of localisation of the brain Define Localisation of Function LOF LOF is the theory that certain areas of the brain correspond to certain functions; in that specific areas of the brain control different functions carried out by the brain. It refers to the idea that behaviour, emotions and thoughts originate in the brain in specific locations.
Selective attention to visual or auditory input is common with damage to the temporal lobes Milner, Left side lesions result in decreased recall of verbal and visual content, including speech perception. Right side lesions result in decreased recognition of tonal sequences and many musical abilities.
Right side lesions can also affect recognition of visual content e. The temporal lobes are involved in the primary organization of sensory input Read, Individuals with temporal lobes lesions have difficulty placing words or pictures into categories.
Language can be affected by temporal lobe damage. Left temporal lesions disturb recognition of words.
Right temporal damage can cause a loss of inhibition of talking. The temporal lobes are highly associated with memory skills.
Left temporal lesions result in impaired memory for verbal material. Right side lesions result in recall of non-verbal material, such as music and drawings.
Seizures of the temporal lobe can have dramatic effects on an individual's personality. Temporal lobe epilepsy can cause perseverative speech, paranoia and aggressive rages Blumer and Benson, Severe damage to the temporal lobes can also alter sexual behavior e.
Common tests for temporal lobe function are: Personality changes with frontal and temporal lesions. Psychiatric Aspects of Neurologic Disease. The neural basis of sexual behavior. Fundamentals of Human Neuropsychology. Visual recognition and recall after right temporal lobe excision in man.
Psychological aspects of focal epilepsy and its neurosurgical management. Advances in Neurology, 8: Solving deductive-reasoning problems after unilateral temporal lobectomy.
Brain and Language, The left side of your brain controls the muscles on the right side of your body, and it is responsible for language along with logical and mathematical thinking. Meanwhile, the right brain controls the muscles on the left side of your body, and it is associated with spatial reasoning and musical.
Harlow’s study () helped to demonstrate localization of brain function, in how different parts of the brain are responsible for specific human activities and behaviour.
State explicitly what area of the brain affected what behaviour in Phineas Gage’s condition. The blood-brain barrier (BBB) provides a constant homeostatic brain environment that is essential for proper neural function.
An unusually low rate of vesicular transport (transcytosis) has been identified as one of the two unique properties of CNS endothelial cells, relative to peripheral endothelial cells, that maintain the restrictive quality of the BBB. Kolb & Wishaw () have identified eight principle symptoms of temporal lobe damage: 1) disturbance of auditory sensation and perception, 2) disturbance of selective attention of auditory and visual input, 3) disorders of visual perception, 4) impaired organization and categorization of verbal material, 5) disturbance of language comprehension, 6) impaired long-term memory, 7) altered.
Localization Function in the Brain Essay Sample. Localization of function refers to the belief that specific areas of the cerebral cortex are associated with specific physical or behavioral functions.
Brain Maps The Study of Brain Function in the Nineteenth Century. The first quarter of the nineteenth century witnessed a growth of interest in the localization of functions in the monstermanfilm.comtedly, Franz Joseph Gall's theory of phrenology, was influential in bringing the attention of the scientific establishment to this possibility, despite the fact that his phrenological theory was based on.
