Brain, Mind, and Pain
In the last issue of Practical Pain Management, I described the notion of resolution, both as prospective intention and a simplification or explanatory separation of something into its component parts.2 I opine that these definitions are not mutually exclusive. Rather I offer the suggestion that if we are to speculate upon, and effectively plan for what pain management could and should be in the future, we must attempt to recognize how pain, and its relief, somehow fit into what I consider to be a big(ger) picture. In this essay I examine how a neuroscience and neurophilosophy of pain arise from, are integrated within, and may be contributory to the natural understanding of the world we live in, the human condition, and the realities, role, and ethics of pain medicine.
Dr. Forest Tennants comments on the concept of neurogenesisthe capacity of neural systems to self-model in response to effects of internal and external environmental factorshas become focal to an understanding of pain and recognition of the capabilities of pain management.3 Indeed, neurogenesis is a likely mechanism by which the nervous system integrates its past, as established by genotypic predispositions, with a capacity to engage its future through potentiation of both local and system-wide network properties to evoke mind. As Hardcastle has stated, any discussion of pain cannot be extricated from an understanding of brain function.4 I agree with Hardcastle in that any meaningful discussion of the brain must also eventually consider the hard question of consciousness. Approaching pain as a simple question of neurosciencethat is, assuming a wholly reductionistic view of pain as merely sense-data produced by activation of discrete units within distinct neural pathwaysfails on an important critical point. Namely, while explaining the effect(s), it does not sufficiently appreciate the relationship of the explanation to that which is being explained (i.e., the explanandum in this case the essence of pain itself). Nor does it regard the actual nature of that which is being explained (i.e., pain as a phenomenal event). Such reductionistic descriptions fail to achieve what is philosophically known as saving the phenomenon and therefore cannot apprehend or regard the facts of pain as an experience.
