the barrel cortex

The barrel cortex is a part of the brain located in the somatosensory area of the cerebral cortex, primarily found in rodents. It processes sensory information from the whiskers (vibrissae), which are highly important for these animals to navigate and explore their environment. The cortex contains distinct barrel-shaped structures that correspond to individual whiskers, allowing precise mapping of tactile signals. This specialized region helps animals interpret touch, texture, and spatial information through their whiskers, supporting their survival and interaction with their surroundings through refined sensory processing.
