Final answer:
The spinothalamic pathway is responsible for pain modulation.
Step-by-step explanation:
The spinothalamic pathway is a neural pathway that carries sensory information related to pain, temperature, and crude touch from the body to the brain. It is part of the larger somatosensory system, which processes sensations from the body and the external environment. The spinothalamic pathway specifically transmits information about noxious (harmful) stimuli and temperature. The spinothalamic pathway is responsible for pain modulation.
