Reply to comment by Paradox_Dolphin in For children who had a major stroke to the left hemisphere of their brain within days of their birth, the infant's brain was 'plastic' enough for the right hemisphere to acquire the language abilities ordinarily handled by the left side while also maintaining its own language abilities as well. by Wagamaga
They would cut their corpus callosum (I probably botched that spelling). It's the biggest and most important communication network between the hemispheres. Without it they struggle to/can't communicate in real time. However, it can cure epilepsy.
It creates a ton of interesting quirks. For instance, the hemispheres can't share everything about what they're seeing with their respective eyes. Sometimes one hand can do something without the opposite hemisphere even knowing about it. The person will generally attempt to explain away the behavior, but the truth is that they don't know exactly what their left hand was doing when they couldn't see it with their right eye.
