What did flourens contribute to psychology?
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 flourens theory of Equipotentiality?
By removing anatomically defined areas of the brain of an animal and watching its behaviour, he thought he might localize certain functions. Flourens did not favour the idea of cerebral localization and concluded that the brain functioned as a whole and thus arose the concept of ‘cerebral equipotentiality’.
How did flourens study the cerebellum?
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.
What did Dr Karl Lashley conclude from his studies about the location of memory in the brain?
Lashley concluded that memories had to be spread all over the brain, throughout all the tissue.
Who invented equipotentiality?
Equipotentiality – a notion developed by Karl Spencer Lashley (1890–1958) positing that all areas of the brain are equally able to perform a task.
What did Pierre flourens do?
Marie-Jean-Pierre Flourens, (born April 15, 1794, Maureilhan, France—died Dec. 6, 1867, Montgeron), French physiologist who was the first to demonstrate experimentally the general functions of the major portions of the vertebrate brain.
What is in the brain stem?
The brainstem is the structure that connects the cerebrum of the brain to the spinal cord and cerebellum. It is composed of four sections in descending order: the diencephalon, midbrain, pons, and medulla oblongata.
What did Lashley find when he removed parts of the brain?
Lashley found that when he removed parts of the brain: the amount of tissue removed was more important than the location.
