LATERALISATION Meaning and
Definition
-
Lateralisation (also spelled lateralization) refers to the process in which various functions and abilities in the human brain become specialized to one hemisphere or the other. It is the phenomenon by which the two hemispheres of the brain exhibit different and distinct functions, allowing for efficient and specialized processing.
The human brain consists of two hemispheres: the left hemisphere and the right hemisphere. These hemispheres are connected by a bundle of nerves known as the corpus callosum. Lateralisation occurs when certain cognitive functions, such as language processing, motor control, and sensory perception, predominantly occur in one hemisphere over the other.
For instance, language processing is primarily localized in the left hemisphere for the majority of individuals (around 90% of right-handed people and 70% of left-handed people). The left hemisphere is also responsible for analytical thinking, logic, mathematical reasoning, and details. On the other hand, the right hemisphere is associated with creativity, intuition, spatial awareness, and holistic thinking.
Lateralisation is believed to optimize brain efficiency by allowing each hemisphere to focus on specific tasks and process information in a streamlined manner. It helps in the specialization of functions, enhancing overall cognitive abilities. However, it is important to note that lateralisation is not an all-or-nothing phenomenon, as both hemispheres often work together, and there is considerable individual variation in the degree of lateralization.
Understanding lateralisation provides insights into brain functioning and its impact on various cognitive processes. Research and studies on this topic contribute to unraveling the complex mechanisms underlying brain lateralisation and its implications for human behavior and cognition.

Etymology of LATERALISATION
The word "lateralisation" is derived from two main components: "lateral" and "-isation" (or "-ization" in American English).
1. "Lateral" comes from the Latin word "lateralis", meaning "of or belonging to the side". It originates from the Latin word "latus", which translates to "side".
2. "-isation" (or "-ization") is a suffix in English derived from the Latin verb form "-izare" (or "-izare" in its Greek form). This suffix is used to form nouns from verbs or adjectives, indicating the process or result of the base word. In this case, the base word is "lateral", so adding the suffix "-isation" creates the noun "lateralisation", meaning the process or result of making something lateral or relating to the side.
