Association fiber
Association fiber
Association fibers are a type of neuronal fiber that connect different parts of the same hemisphere of the brain. They are part of the white matter of the brain and are essential for the integration of information between different brain regions.
Pronunciation
The term "Association fiber" is pronounced as /əˌsoʊsiˈeɪʃən ˈfaɪbər/.
Etymology
The term "Association fiber" is derived from the Latin word 'associare' which means 'to join' or 'to connect', and the Old English word 'fibre' which means 'a thread or filament'. This refers to the function of these fibers in connecting different parts of the same hemisphere of the brain.
Types of Association Fibers
There are two main types of association fibers: short association fibers and long association fibers.
- Short Association Fibers (U-fibers): These fibers connect adjacent gyri within the same lobe of the brain. They are important for the communication between neighboring areas of the brain.
- Long Association Fibers: These fibers connect distant gyri within the same hemisphere. They include the superior longitudinal fasciculus, the inferior longitudinal fasciculus, the uncinate fasciculus, and the cingulum.
Function
Association fibers play a crucial role in integrating information between different regions of the brain. They allow for the communication and coordination of various brain functions, contributing to processes such as cognition, memory, and language.
