AP PSYCHOLOGY

Detailed explanation-1: -To test Gall’s assertions, Flourens developed ablation as a procedure to explore the workings of the brain.

Detailed explanation-2: -a French surgeon, applied the principle of experimental ablation to the human brain. Of course, he did not intentionally remove parts of human brains to see how they worked. Instead, he observed the behavior of people whose brains had been damaged by strokes.

Detailed explanation-3: -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.

Detailed explanation-4: -Through a series of crude ablation experiments on the brains of pigeons and lower vertebrates (1822-1824), Flourens determined the presence of a motor centre in the medulla oblongata and coordination in the cerebellum.
