Left Hemisphere

The Left Hemisphere (pronunciation: /lɛft ˈhɛmɪsfɪər/) is one of the two cerebral hemispheres in the brain of vertebrates. It is the hemisphere on the left side of the brain in right-handed individuals, and it controls the right side of the body.

Etymology

The term "hemisphere" comes from the Greek words "hemi" meaning "half" and "sphaira" meaning "sphere". The term "left" is derived from the Old English "lyft", which means "weak" or "foolish", as the left side was often associated with these qualities in ancient times.

Function

The Left Hemisphere is primarily responsible for controlling the right side of the body and is typically associated with performing tasks that have to do with logic, such as in science and mathematics. It is also involved in language processing, including grammar and vocabulary.
