Karl Lashley

In this context when we use brain we are referring to the cortex. In behaviorismthe theory of equipotentiality suggests that any two stimuli can be associated in the brain, regardless of their nature.

By the s two separate equipofencialidad had grown out of Lashley’s research: If the area is not destroyed then the cortex can take over another part.

The law of mass action says that the efficiency of any complex function of the brain is reduced proportionately to how much damage the brain as a whole has sustained, but not to the damage of any particular area of the brain. He reached this erroneous conclusion due to imperfect lesioning methods. This led Lashley to conclude that memories are not localized, but that they are widely distributed across the cortex.


Equipotentiality refers to a psychological theory in both neuropsychology and behaviorism.

June 7, Davis, West Virginia. Together the two conducted field experiments and studied the effects of different drugs on maze learning of rats. A Quantitative Study of Injuries to the Brain disproved the idea of localization and equiptoencialidad to life the idea that the brain and its multiple parts work together for memory and other functions.

Warren Robert S. This starts to go against localization theories which would say that the brain is only functioning in specific regions and the brain’s ability to perform at any given task is only effected by the overall damage to that area of the brain and damage to an unrelated area shouldn’t affect the task. National Academy of Sciences.


Lashley was a very active boy, both physically and mentally. Continuing the ceerbral for the engram: Archived from the original on What they found was that the mice had no deficits finding the food if the lesions were in a specific part of the brain but if the lesions damaged a equipltencialidad portion of the brain, they did have troubles finding equipotecialidad.

Stanley Hall I. Karl Spencer Lashley defined equipotentiality as “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]”.

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. Meehl Charles E. Watson had cerebrap most influence on Lashley. Lashley was also a pioneer in challenging the way we think about human and animal behavior in terms of our biology.
