Lashley contributed to psychology and neuropsychology in a number of ways. First, his publication, "Brain Mechanisms and Intelligence: A Quantitative Study of Injuries to the Brain" (1929) found evidence to suggest the idea of localization was wrong and brought to life the idea that the brain and its multiple parts work together for memory and other functions. Second, researchers began to copy his studies and also started to investigate what parts of the brain work together. They also began studying deficits people may have along with parts of their brain that may be damaged to see if there is a correlation between them.
