Sensory cortex
Sensory Cortex
The Sensory Cortex (pronunciation: /ˈsɛnsəri ˈkɔːtɛks/) is a part of the cerebral cortex responsible for processing sensory information within the human brain.
Etymology
The term "Sensory Cortex" is derived from the Latin words 'sensus' meaning 'sense' and 'cortex' meaning 'bark' or 'rind'. This term was first used in the late 19th century to describe the area of the brain that processes sensory input.
Function
The Sensory Cortex is divided into primary and secondary areas. The Primary Sensory Cortex receives signals from sensory neurons, and the Secondary Sensory Cortex processes those signals using associative areas. The Sensory Cortex is involved in the processing of all five senses: sight, sound, touch, taste, and smell.
