Definitions:

Gate Control Theory

A theory positing that pain signals encounter nerve gates at the spinal cord level that can block or allow the sensation of pain to travel to the brain.

Lateral Spinothalamic Tract

A pathway in the spinal cord that transmits pain and temperature sensations to the brain.

Anterior Spinothalamic Tract

The anterior spinothalamic tract is a sensory pathway of the spinal cord that carries information about light touch and pressure to the brain.

Tertiary Neurons

Neurons that receive signals from secondary neurons and typically transmit them to the brain or spinal cord for integration.
