The young participants showed greater brain activation when observing younger versus older people receiving painful stimuli, and they rated the needle-touch to the younger people to appear more painful and more personally distressing. Furthermore, those participants reporting a greater level of contact with older adults at work showed less brain activation in the left insula cortex, a typical neural marker for observed pain, when observing painful touch to the older people. These have implications for understanding both the emotional responses and perception of pain of young adults when observing pain in the elderly.
