Corpus callosum. A corpus callosotomy (/ k ə ˈ l ɔː s (ə) t ə m iː /) is a palliative surgical procedure for the treatment of medically refractory epilepsy. [1] The procedure was first performed in 1940 by William P. van Wagenen. [2]
The symptoms of refractory (difficult to treat) epilepsy can be reduced by cutting through the corpus callosum in an operation known as a corpus callosotomy lobotomy paralysis. [28] This is usually reserved for cases in which complex or grand mal seizures are produced by an epileptogenic focus on one side of the brain, causing an ...
At the time this article was written, only ten patients had undergone the surgery to sever their corpus callosum (corpus callosotomy). Four of these patients had consented to participate in Sperry and Gazzaniga's research. After the corpus callosum severing, all four participants' personality, intelligence, and emotions appeared to be unaffected.
Corpus callosotomy is a palliative procedure for specially severe cases of epilepsy. This corpus callosum is a large bundle of nerve fibers that connects both brain halves with each other. To prevent the spreading of seizures from one brain hemisphere (brain half) to the other the corpus callosum can be split.
William Van Wagenen proposed the idea of severing the corpus callosum to eliminate transcortical electrical signals across the brain's hemispheres. [5] If this could be achieved, then the seizures should be reduced or even eliminated. [citation needed] The general procedure of a corpus callosotomy is as follows. The patient is put under anesthesia.
In neurosurgery, as a treatment for severe epilepsy, the corpus callosum, or the area of the brain that connects the two hemispheres, would be completely bisected.By eliminating the connection between the two hemispheres of a patient's brain, electrical communication would be cut off greatly diminishing the amount and severity of the epileptic seizures.
The longitudinal fissure plays a key role in corpus callosotomy, neurosurgery resulting in split brain, as it provides unobstructed access to the corpus callosum. Corpus callosotomy is one of the procedures used for pharmacologically treating intractable epilepsy cases, and it consists of the division of the nerve fibers running between the two ...
Dejerine in 1892 described specific symptoms resulting from a lesion to the corpus callosum that caused alexia without agraphia. The patient had a lesion in the left occipital lobe, blocking sight in the right visual field , and in the splenium of the corpus callosum. Dejerine interpreted this case as a disconnection of the speech area in the ...
