The brain is made of matter. The mind is made of ideas. How does a physical object give rise to thoughts, memories, and consciousness? This is the central question of neuroscience.

Mind refers to ideas, purposes, and the ability to find patterns in the world. Brain is the material object — cells, chemicals, electrical signals. The brain's dynamics somehow implement the mind. We don't fully know how.

Modern neuroscience can map the brain with remarkable precision — we now know that different regions of the neocortex (the outer, folded surface) are dedicated to specific functions.

Cerebral cortex geography — colour-coded by lobe

Each lobe handles a different domain:

• Occipital lobe → Primary Visual Cortex — the first stop for everything you see
• Temporal lobe → Auditory Cortex (hearing) + Wernicke's area (understanding language)
• Frontal lobe → Motor Cortex (voluntary movement) + Broca's area (producing speech) + prefrontal areas for planning and decision-making
• Parietal lobe → Somatosensory Cortex — maps touch, pain, and body position
