SECTION OF CORPUS CALLOSUM IN EXPERIMENTAL EPILEPSY IN THE MONKEY

Abstract

THE EFFECT of section of the corpus callosum on human epilepsy remains a controversial issue. Van Wagenen and Herren¹found that in patients with generalized convulsions section of commissural pathways contained in the corpus callosum limited the spread in a unilateral convulsion with no loss of consciousness. Erickson,²using electrical stimuli, showed that in the monkey section of the corpus callosum played a definite role in the spread of a discharge from one hemisphere to the other. Curtis³concluded that the typical response to the application of a convulsant drug in monkeys and cats was mediated by the corpus callosum and abolished by its section. Obrador Alcalde,⁴studying convulsive attacks produced by electrical stimulation of the cortex in cats, reported that section of the corpus callosum did not change the fundamental character of the convulsions and concluded that the corpus callosum was not an association system
