What procedure did flourens develop?

To test Gall’s assertions, Flourens developed ablation as a procedure to explore the workings of the brain. By removing anatomically defined areas of the brain of an animal and watching its behaviour, he thought he might localize certain functions.

What is flourens theory of Equipotentiality?

In neuropsychology, equipotentiality is a neurological principle that describes a cortical mechanism, first identified by Jean Pierre Flourens and later revisited by Karl Lashley in the 1950s. His principle of “mass action” stated that the cerebral cortex acts as one—as a whole—in many types of learning.

Who discovered experimental ablation?

Marie Jean Pierre Flourens
It was pioneered in 1824 by the French physiologist Marie Jean Pierre Flourens (1794–1867) and is also called a lesion experiment.

Which of the following is a contribution of Pierre flourens?

Flourens proposed that the semicircular canals were involved in the maintenance of posture and balance. He hypothesised that a lesion in the semicircular canals was responsible for the previously described vestibular symptomatology. Flourens was accepted as a pioneer of the modern theory of brain function.

What is experimental ablation?

experimental ablation. The removal or destruction of a portion of the brain of a laboratory animal; presumably, the functions that can no longer be performed are the ones the region previously controlled.

What is equipotentiality premise?

The premise of equipotentiality, which has been widely adhered to among learning theorists, states that the laws of learning should not vary with the use of particular stimuli, responses, or reinforcements.

What did Lashley develop by purposely damaging?

How did Lashley develop the equipotentiality hypothesis? He trained rats in the correct route through a maze, then deliberately damaged their brains and observed that this did not inhibit their progress through the maze.

Is heart ablation major surgery?

Open-heart maze. This is major surgery. You’ll spend a day or two in intensive care, and you may be in the hospital for up to a week. At first, you’ll feel very tired and have some chest pain.

Why are brain ablation experiments considered unethical on humans?

Such research is considered unethical on humans due to the irreversible effects and damages caused by the lesion and by the ablation of brain tissues. However, the effects of brain lesions (caused by accidents or diseases) on behavior can be observed to draw conclusions on the functions of different parts of the brain.

What method did Pierre flourens use to investigate cortical Localisation?

ablation
To test Gall’s assertions, Flourens developed ablation as a procedure to explore the workings of the brain. By removing anatomically defined areas of the brain of an animal and watching its behaviour, he thought he might localize certain functions.

What is experimental ablation used for?

The method of removal of part of the brain was termed “experimental ablation”. With the use of experimental ablation, Flourens claimed to find the area of the brain that controlled heart rate and breathing. Ablative brain surgery is also often used as a research tool in neurobiology.

What is the law of equipotentiality?

in learning theory, the principle that any pair of stimuli can be associated with equal ease, regardless of their nature or origin. Also called law of equipotentiality; principle of equipotentiality.
