Cortical remapping

Cortical Remapping

Cortical remapping, also known as cortical reorganization, refers to the phenomenon where a cortical map is 'reorganized' due to sensory input changes. This is a fundamental mechanism through which the brain adapts to changes in the body or in the environment.

Pronunciation

/kɔːrˈtɪkəl riːˈmæpɪŋ/

Etymology

The term 'cortical remapping' is derived from the words 'cortex', referring to the outer layer of the brain, and 'remapping', which means to change the plan or arrangement of something.

Overview

Cortical remapping is a process that involves the brain's ability to change its neural pathways and synapses in response to new experiences, development, damage, or dysfunction. This process is facilitated by the brain's neuroplasticity, which allows the brain to reorganize itself by forming new neural connections throughout life.

Cortical remapping can occur in various parts of the brain, including the motor cortex and the somatosensory cortex. It is often observed in individuals who have lost a limb, leading to a phenomenon known as phantom limb syndrome, where the brain remaps the area of the cortex associated with the missing limb to an adjacent area.
