Entangled brains and the experience of pains

Area of Science:

• Neuroscience
• Pain Research
• Computational Neuroscience

Background:

• The International Association for the Study of Pain (IASP) updated its definition to "an unpleasant sensory and emotional experience."
• Current models for understanding pain without clear brain correlates include eliminativism, multiple realizability, and affordance-based approaches.

Purpose of the Study:

• To propose a novel framework for understanding the neurobiological basis of pain.
• To challenge the prevailing assumption that specific brain correlates for pain are absent.

Main Methods:

• Analogy between brain mechanisms for 3D spatial navigation in animals and the brain's creation of pain.
• Conceptualization of brain function as a large-scale combinatorial system with feedback loops.

Main Results:

• Brain function is characterized by dynamic patterns, akin to whirlpools, rather than fixed structures like combustion engines.
• Pain experiences are proposed as context-dependent, spatiotemporal trajectories reflecting complex neural activity.

Conclusions:

• The assumption of absent specific pain correlates is misguided.
• Pain experiences emerge from heterogeneous, multiplex, and dynamically adaptive neural processes.
• A dynamic, combinatorial systems approach offers a more accurate model for pain perception.
