CAUSE
One question. One truth.
“Why we feel pain”
Pain is primarily caused by activation of nociceptors—specialized nerve endings that detect harmful stimuli such as tissue damage—and the transmission of these signals to the brain, where they are processed to produce the sensation of pain as a protective mechanism.

CURRENT STATE
Nociceptors throughout the body detect damaging stimuli and send electrical signals to the spinal cord and brain. The brain integrates these signals in multiple regions to identify pain location, intensity, and emotional significance, enabling an adaptive response to injury or threat.
