Why is the brain considered the real sense organ?

The brain is considered the real sense organ primarily because sensations are not experienced until the brain processes the sensory impulses received from the various sensory organs. When sensory receptors in the body detect stimuli, they convert these signals into electrical impulses that travel through sensory pathways to the brain. It is in the cerebral cortex, specifically, where these impulses are interpreted, leading to the conscious perception of sensations such as taste, touch, sight, sound, and smell.

This view underscores that while organs such as the eyes or ears are critical for detecting stimuli, it is ultimately the brain that integrates and interprets these signals, creating the experience of sensation. Therefore, the role of the brain is pivotal in transforming raw sensory data into meaningful experiences, establishing its prominence as the central organ of perception.
