What is the biggest sense in the human Brian?

The biggest sense in the human brain is often considered to be vision, as it occupies a significant portion of the cerebral cortex—approximately 30% of the brain's surface area is dedicated to processing visual information. The visual system plays a crucial role in how we perceive and interact with our environment, influencing our understanding and decision-making. This predominance of vision underscores its importance in navigation, communication, and daily functioning.
