Neuroscience of Pain and Pleasure | Part I

What are the neural pathways underlying pain and pleasure? Why is it that some find a flogging more painful than others? Why is it that for some, the pain can be extremely pleasurable? Why is it that for some, pain is gradual and others, chronic?

This class examines the neurobiological mechanisms underlying the pain and pleasure pathways within the context of BDSM (Bondage/Discipline, Dominance/Submission, Sadism/Masochism). Drawing upon current neuroscience research, we identify nociception as a varied physiological pain development process and as a subjective perceptual experience.

We will explore the predictive coding framework to explain how contextual factors frame expectation and therefore modulate pain perception, with specific applications to impact play and sensory play in BDSM. The class touches upon the neural overlaps between pain and pleasure processing, deeming them not on a binary scale but part of a larger reward circuitry.

We will further address common misconceptions regarding dopamine's role in reward, testosterone's relationship to aggression, and the non-existence of human pheromones, providing evidence-based corrections to these "neuromyths." By integrating empirical findings with practical examples from consensual kink practices, this class offers a comprehensive framework for understanding how the brain constructs subjective experiences of pain and pleasure.
