Brainmapping aims to uncover the relationship between the structure and function of the brain. This would be an invaluable tool for a range of psychiatric disorders and cognitive impairments. neuroscience neurology connectome neuroimaging
Lesion Studies and Their Influence in NeuropsychologyBrain Mapping at a Cellular Level: the Connectome Neuropsychology is a subdivision of psychology and neurology which refers to the relationship between an individual’s behavior and the physiological processes of the brain and central nervous system.
Techniques to uncover brain maps Various tools developed over the last century have alluded to localization of function in the brain. This marriage of cognitive psychology and functional brain imaging has included neuroimaging techniques such as: functional magnetic resonance imaging , positron emission tomography, electroencephalography, electrocorticography and near-infrared spectroscopy, a recently emerging tool.
Seminal articles in the mid to late 20th century included influential works that revealed hippocampal lesions were associated with impaired memory and injuries to the Wernicke area were responsible for language comprehension deficits.
Adversely, however, prefrontal cortex activation declines during aging, and was found to be significantly reduced in frontotemporal dementia patients. Other examples include studies that have exposed subjects to a range of facial expressions during scanning, which identified the importance of the amygdala in social behavior and recognition of facial expressions and emotion.
Brain mapping at a cellular level: the connectome Brain mapping can additionally be investigated at a cellular level and therefore gave rise to the study of the ‘connectome’, a “comprehensive structural description of the network of elements and connections forming the human brain”.
