today in psychology we were talking about the two brain hemispheres and we watch a video on a guy with epilepsy and to control it they seperated his left hemisphere from his right. the treatment worked but how do doctors know that taking a risk with such a delicate and essential part of the body wont result in death or other problems? i mean they have to experiment some how dont they? so what do they experiment on animals such as primates since they are the closest thing to us? or do they experiment on human beings?

First experiments are on animals, often dogs. When those can be shown to work, they try it on humans desperate enough for a cure to take a chance.

Philo is right. Lots of experimentation on animals and then eventually humans. For treatments that have been tried although radical, there is VERY extensive testing beforehand. MRI, EKG, Brain Scan's etc.
