The brain's two hemispheres in split-brain patients showcase independent functions with the left brain verbalizing actions of the non-verbal right brain, raising questions about self and consciousness. Split-brain patients can simultaneously draw two separate objects with each hand, highlighting the distinct capabilities of each hemisphere.
Insights
- The brain's hemispheres work independently in split-brain patients, causing conflicting actions due to severed communication, revealing the presence of two distinct minds within one individual.
- While the left brain can verbalize and explain actions, the right brain lacks speech but can perform tasks independently, raising questions about self and consciousness in individuals with split-brain conditions.
