The unpleasantness of pain is an emotional phenomenon distinct from pain’s sensory qualities. To study how the brain processes pain-related emotions, Corder et al used neural calcium imaging in freely behaving mice. The team identified brain circuits that respond to pain and directly tested their causal role in motivational behaviors associated with acute and chronic pain.
