Lateralization of brain function

Lateralization of Brain Function

Lateralization of brain function refers to how some neural functions, or cognitive processes tend to be more dominant in one hemisphere than the other. The human brain is divided into two hemispheres–the left and the right hemisphere–each of these hemispheres are responsible for different functions.

Pronunciation

Lateralization: /ˌlatərəlɪˈzeɪʃ(ə)n/

Etymology

The term "lateralization" comes from the Latin word "latus" which means "side".

Overview

The concept of lateralization of brain function is rooted in the phrenological theories of the 19th century. Modern neuroscientific research has substantiated the basic idea, although the specifics are more complex than early theorists imagined.

Left Hemisphere

The left hemisphere is often identified as being more responsible for sequential processing, and language production. It is also associated with mathematical abilities and logical thinking.

Right Hemisphere

The right hemisphere is typically associated with holistic processing, and is often linked with spatial abilities, face recognition and music perception.
