Split Brain: A Shocking Tale of Self-Awareness

In 1939, ten epilepsy patients underwent a radical surgery: severing the corpus callosum to separate the brain's hemispheres. Early studies suggested no cognitive impairment. However, in the 1960s, Gazzaniga and Sperry's tests revealed a shocking truth: the hemispheres functioned independently, each with its own conscious stream, even 'arguing' over perceptions. This overturned understanding of the brain and self, offering new perspectives on consciousness. Research continues, exploring how each hemisphere perceives the self.
