Similarly, it is necessary to divide from proximal to the origin of the calloso-marginal artery of the ipsilateral anterior cerebral artery (2,8,28,36) In the second step, a cottonoid is placed in the foramen of Monroe to protect the underlying choroid plexus and prevent the blood and debris entering the ventricular system for what the callosotomy by interhemispheric aprroach is performed.
atonic seizures (drop attacks) are ideal cases for corpus callosotomy, as this prevents generalisation to the contralateral cortex.

However, the availability of alternative treatments such as drug therapies, and various surgeries such as pallidotomy and thalamotomy for treating Parkinson's disease; lobe resection, lesionectomy, and corpus callosotomy for treating epilepsy, acts as major restraints for the growth of the global market of neurostimulation devices.

Ogawa et al6 reported that spike-monitoring of anaesthesia using bilateral BIS monitoring was useful during corpus callosotomy for the treatment of epilepsy to assess the effects of anaesthesia and the therapeutic effects of the surgery.

Callosotomy in the management of refractory epilepsy
Cerebral epilepsy surgery (corpus callosotomy, temporal lobectomy, and hemispherectomy) may offer control or diminution of seizures in 10%-25% of those with poorly controlled seizures, but many patients are not optimal candidates or choose not to consider this option.
The answer to what went on during Tichy's crucial mission to the moon resides in the right hemisphere of his brain, which, of course, cannot communicate what it knows through ordinary linguistic means because those means have been denied it by the callosotomy.
