Question

Quizplus · Accepted Answer

The gate-control theory of pain proposes that there is a "gate" located in the spinal cord that can regulate the transmission of pain signals to the brain. This gate is influenced by both physiological (e.g. the activity of nerve fibers) and psychological factors (e.g. attention, anxiety). When the gate is "closed", it prevents pain signals from reaching the brain, which can help explain why certain distractions or interventions (such as massage or heat) can reduce pain perception.
