Subject 1 with a lesion in the "A" region of the brain may show impaired functioning in cognitive ability "X" but not "Y", while subject 2 with a lesion in area "B" demonstrates reduced "Y" ability but "X" is unaffected; results like these allow inferences to be made about brain specialization and localization, also known as using a double ...
[30]: 107 [31] Interestingly, research has shown quite opposite function of brain lateralisation, i.e. right hemisphere creatively and chaotically links between concepts and left hemisphere tends to adhere to specific date and time, although generally adhering to the pattern of left-brain as linguistic interpretation and right brain as spatio ...
Franz Joseph Gall or Franz Josef Gall (German:; 9 March 1758 – 22 August 1828) was a German neuroanatomist, physiologist, and pioneer in the study of the localization of mental functions in the brain. Claimed as the founder of the pseudoscience of phrenology, [1] Gall was an early and important researcher in his fields.
Functional specialization is the idea that functions are localized within the brain and can only be carried out by particular area(s) of the brain. [citation needed] Some tasks appear to work on the mass action principle, with lesions causing less drastic effects than would be expected if the tasks were localized within the brain.
In the 1800s brain localization theories were the popular theories on how the brain functioned. [1] The Broca's area of speech was discovered in 1861, in 1870 the cerebral cortex was marked as the motor center of the brain, and the general visual and auditory areas were defined in the cerebral cortex.

The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral cortex, that is supported by an inner layer of white matter. In eutherian (placental) mammals, the hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers.
Cognitive neuropsychology places a particular emphasis on studying the cognitive effects of brain injury or neurological illness with a view to inferring models of normal cognitive functioning. Evidence is based on case studies of individual brain damaged patients who show deficits in brain areas and from patients who exhibit double ...
Another debate arose about localization of function or functional specialization versus equipotentiality which played a significant role in the development in behavioral neuroscience. As a result of localization of function research, many famous people found within psychology have come to various different conclusions.
