Lashley coined the term equipotentiality to define the idea that if one part of the brain is damaged, other parts of the brain will carry out the memory functions for that damaged part. "The apparent capacity of any intact part of a functional brain to carry out… the [memory] functions which are lost by the destruction of [other parts]". [1]
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.
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 ...
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.
[5] [6] His study of V1 (primary visual cortex) led him to believe that it was a site of learning and memory storage (i.e. an engram) in the brain. He reached this erroneous conclusion due to imperfect lesioning methods. By the 1950s, two separate principles had grown out of Lashley's research: mass action and equipotentiality. "Mass action ...
Connectome: How the Brain's Wiring Makes Us Who We Are (2012) is a book by Sebastian Seung. It introduces basic concepts in neuroscience and then elaborates on the field of connectomics , that is, how to scan, decode, compare, and understand patterns in brain connectivity.
In addition, Toulouse seemed to have a lively nightlife, which makes sense considering the many nearby universities. It was a bit too much for me, especially since this meant we heard many loud ...
Lesion network mapping is a neuroimaging technique that analyzes the connectivity pattern of brain lesions to identify neuroanatomic correlates of symptoms. [1] [2] [3] The technique was developed by Michael D. Fox and Aaron Boes to understand the network anatomy of lesion induced neurologic and psychiatric symptoms that can not be explained by focal anatomic localization.
