... There is a neural link between the left and right hemispheres of the brain, known as the
corpus callosum. This link is sometimes surgically severed to control severe seizures in
epilepsy patients. Tests of these patients have shown that, after the link is completely
severed, the hemispheres are no l ...

14 and was able to graduate a university. What would be your prediction on Ahad’s future
accomplishments, if Ahad was to lose his left hemisphere?

... In an additional experiment, words are flashed briefly to the left or right visual field of the
participant. Try to predict the results. For example, when the word appears in the left visual field,
will the person be able to read the word?
... The joking comment that one function of the corpus callosum is “to propagate seizures” refers to what
sometimes occurs in people with epilepsy caused by abnormal activity in the cerebral cortex. This abnormal
electrical activity may spread from its starting point in one hemisphere of the cortex and ...

... The corpus callosum is a large ban of neural fibers
that connects the two hemispheres of the brain.
In some surgeries, the fibers are severed which
cuts off communication between the two
hemispheres of the brains. This is used as a
form of treatment for epileptic seizures.

Dual consciousness is a concept developed by Frantz Fanon in his book Black Skins, White Masks. It deals with the nature of the colonized subject, and the way in which they must simultaneously embrace two different cultural identities. It is mostly used in discussions of post-colonialism, but is also important to other fields within critical theory.For a more complete understanding- the original concept ""double consciousness"" was used and explained in depth years before by W. E. B. Du Bois. Here “double consciousnesses,” which according to Du Bois means a “sense of always looking at one’s self through the eyes of others”.
