Karl Lashley

Explicit use of et al. In this context when we use brain we are referring to the cortex. This would suggest that just one part of the brain is not responsible for memory and localization was totally ruled out. The first was his mother Maggie Blanche Spencer.

Breve História da Neurociência Cognitiva by Émille Dias on Prezi

Goodheart Melba J. Franz made multiple lesions in specific parts of the brains and after they healed, put them through the maze to see if they had deficits in finding the food. If the area is not destroyed then the cortex can take over another part.

Through Lashley’s ideas of equipotentiality and the law of mass action, he is equipotencialidsd that the brain is functioning as a whole unit and that over all damage to the brain effects it’s over all functioning. An introduction to the history of psychology.

Views Read Equipoyencialidad View history. Ghiselli and Brown did an experiment where they destroyed various subcortical regions of the brain in rats and tested their abilities to cerebal mazes compared to rats with no damage done to their brains. 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.

Anton Susan H. John Black Johnston, a professor at West Virginia University named, taught the first zoology course that Lashley took. First, his publication, Brain Mechanisms and Intelligence: The data gathered from these tend to confirm Lashley’s theories.


When speaking of this professor, Lashley wrote, “Within a few weeks in his cerebeal I knew that I had found my life’s work”. Retrieved November 21, from http: She was a strong advocate of schooling, and she encouraged Equipotenncialidad intellectually from an early age; as a result he was able to read at the age of four. While working on his PhD in genetics, Lashley began a number of tests on brain tissue and the idea of localization. He equipotencialiead at West Virginia Universitywhere he had originally intended to become an English major.

Today we know that distribution of engrams does in fact exist, but that the distribution is not equal across all cortical areas, as Lashley assumed. By using this site, you agree to the Terms of Use and Privacy Policy.

Biographical Memoirs of Fellows of the Royal Society. Lashley has always equpotencialidad his family in high regard.

Sincethe Society has awarded the annual Karl Spencer Lashley Award in recognition of work on the integrative neuroscience of behavior.

Together the two conducted field experiments and studied the effects of different drugs on maze learning of rats. Lashley’s father held various local political positions. If cortical equipotenciapidad is destroyed following the learning of a complex task, deterioration of performance on the task is determined more by the amount of tissue destroyed than by its location.

Equipoteencialidad Wikipedia, the free encyclopedia. Fellows of the Royal Society elected in After performing ablation experiments on birds, and seeing that they could still fly, peck, mate, sleep, and perform a range of other regular behaviors, Flourens concluded that every area of the brain was capable of equipotencislidad what every other area of the brain could, but only for higher-level functions which he called “perception”.

In equipotecialidad first experiments, Lashley was in charge of building different mazes for the rats to go through and Franz was in charge of making the lesions in the rats’ brains.

A Review of General Psychology equipoteencialidad, published inranked Lashley as the 61st most cited psychologist of the 20th century. Researchers also expanded the study of working memory, central executive, and further research on memory deficits and learning.


These two principles grew out of Lashley’s research on the cortical basis of learning and discrimination. In the s brain localization theories were the popular theories on how the brain functioned. Karl Spencer Lashley June 7, — August 7, was a psychologist and behaviorist remembered for his contributions to the study of learning and memory.

June 7, Davis, West Virginia. Another man that Lashley equipotencialiddad was Roger Sperry.

Archived from the original on August 1, While there he also carried out research which he used for his master’s thesis. In neuropsychologyequipotentiality is a neurological principle that describes a cortical mechanism, first identified by Jean Pierre Flourens and later revisited by Karl Lashley in the s.

He took a course in zoologyhowever, and switched his major to zoology due to his interactions with a professor. In Februarywhile doing his teaching at Harvard, Lashley unexpectedly collapsed and was hospitalized.

Warren Robert S. He has said that his father was a kind man. equioptencialidad

There has also been experimental work done on higher apes and also studies done on humans who have suffered brain damage in various ways. Retrieved from ” https: However, equipotentiality and the law of mass action don’t mean that there is no localization. Lashley was born on June 7, in the town of Davis, West Virginia. It proposes that all forms of associative learningboth classical Pavlovian and operant Skinnerian involve the same underlying mechanisms.

He trained rats to perform specific tasks seeking a food rewardthen lesioned specific areas of the rats’ cortex, either before or after the animals received the training. He also argued that elementary sensory input was localized, which is supported by current research.
