Consciousness Research Through Pain.
Healthcare (Basel, Switzerland) February 6, 2025 Dong Ah Shin, Min Cheol Chang
Pain offers a measurable model for studying consciousness because both involve subjective experience and neural activity. Key theories like Global Workspace Theory and Integrated Information Theory provide frameworks for understanding consciousness, while pain research highlights how subjective interpretation and emotional context shape sensory experiences. Brain regions such as the anterior cingulate cortex and insula bridge sensory and emotional dimensions. Current methods struggle to objectively measure subjective phenomena, making neural correlates important. This work suggests that leveraging pain as a proxy can advance understanding of consciousness, with implications for mental health treatment and artificial intelligence.
