LEFT HEMISPHERE Meaning and
Definition
-
The left hemisphere, also known as the left cerebral hemisphere, is one of the two main divisions of the brain and is responsible for a range of cognitive functions. It is located on the left side of the brain and is the dominant hemisphere in the majority of right-handed individuals, as well as in a significant proportion of left-handed individuals.
The left hemisphere is primarily associated with logical reasoning, analytical thinking, language processing, and mathematical abilities. It controls and receives sensory information from the right side of the body and is involved in the control of movements on the right side. It also plays a crucial role in processing and producing speech.
Furthermore, the left hemisphere is responsible for sequential and linear processing, as well as verbal memory and retrieval of stored information. It is involved in understanding and producing language, including speech sounds, grammar, and vocabulary. Additionally, it is associated with interpreting and processing information in a literal and concrete manner.
However, it is important to note that while the left hemisphere specializes in certain functions, it works in conjunction with the right hemisphere to perform complex cognitive tasks. Both hemispheres collaborate through the corpus callosum, a bundle of nerve fibers that facilitates communication between them.

Etymology of LEFT HEMISPHERE
The word "hemisphere" comes from the combination of two Greek words: "hemi" (meaning half) and "sphaira" (meaning sphere or ball). "Hemi" was derived from the Proto-Indo-European root "semi-" or "hemi-", which also gave rise to the English word "half".
The word "left" has Old English origins and can be traced back to the Proto-Germanic word "leftaz". It is believed to have originally meant "weak" or "no longer whole" and was associated with the non-dominant hand.
When these two words are combined, we get "left hemisphere", signifying the half of the brain located on the left side of the human skull.
