The brain is divided into two hemispheres, which is a common feature across many species, not just humans. This division raises interesting questions about its purpose and implications for brain function.

The asymmetry of the brain is peculiar because it seems unnecessary for simply increasing space; one would expect a symmetrical expansion if that were the case.

The left hemisphere is adept at processing explicit, clear information, while the right hemisphere excels at understanding implicit, nuanced meanings, which is crucial for grasping complex human experiences.
