The somatosensory cortex is organized somatotopically, meaning different regions of the cortex are dedicated to processing sensory information from different parts of the body.

The fingers have a high concentration of sensory receptors, allowing for precise tactile discrimination, and thus occupy a larger area of the somatosensory cortex compared to the chest, shoulder, or thigh.
