Quick Summary

The left hemisphere is one of the two halves of the cerebral hemispheres in the human brain. It is predominantly associated with analytical and logical thinking, as well as language processing, including comprehension and expression. In most right-handed individuals, the left hemisphere is dominant for language functions. It also plays a role in programming complex movements and understanding one's own body. Damage to the left hemisphere can lead to conditions like aphasia (language impairment) and apraxia (difficulty performing purposeful actions).123
