Like in most surgical procedures such as this one, there are also not so good things about it. Reactions to stimuli are limited to only one side of the body on people that have had their corpus callosum removed. Split-Brain people can only tell what they see on the left field of their vision while they can't on the opposite direction.
Overall, i found this procedure to not be so bad after all. It may affect some things negatively, but affects other things in a positive way. The question about wether the removal of the corpus callosum is bad or not that bad is a big and confusing debate to address.
I found this subject about the severed corpus callosum very interesting and something worth to talk about. Let me know what you all think about this.
