“I dare say wires being crossed is quite an appropriate metaphor, as fMRI studies have documented masochists activating brain areas involved in sensory processing rather than affective pain processing when they receive painful stimuli within that particular context.” He nodded. “But through involvement of the parietal operculum, which suggests additional cognitive evaluation, not the ventral striatum, which would suggest the processing of rewards.”

In other words, it was less about pleasure and more about memory and cognitive reevaluation. Which seemed to fit with Rekker’s desire to remain in control of his pain. At least partially.

That revelation made Isamu pause.

“Hmm… That runs counter to what a number of studies have found, but that does not mean it cannot be ruled out. After all, opioid and dopaminergic systems and the HPA axis can both be activated either by psychoactive drugs or by behaviors. So it is still plausible that for a subset of cases, the same biological mechanisms support the development of addiction as well as self-harming behaviors.”

Comorbidity at its finest. Wires getting crossed.

Isamu’s eyes widened for a moment, though he felt no need to ask for clarification. He could easily read between the lines, and scoffed a hasty, “whatever releases dopamine in your nucleus accumbens, I suppose…”

That sort of thing was not a turn-on for the scientist. And unfortunately, very little scientific literature actually existed on that particular subject to fill in the gaps.
