Wall and Melzack's Model
Wall and Melzack's model explains how our brain perceives pain, highlighting that pain isn't just a direct result of injury but is influenced by multiple factors. It suggests that sensory signals from injury travel to the brain via the spinal cord, but the brain also modulates these signals based on context, emotions, and attention. For example, stress or distraction can amplify or diminish pain perception. This model emphasizes that pain is a subjective experience shaped by both physical stimuli and psychological factors, demonstrating why two people with similar injuries can perceive pain differently.
