More recently, research has shown that certain drugs like cocaine and heroin amplify this effect - an action that may lie at the heart of drug addiction. Now, a new study from the University of Michigan adds a new twist to dopamine's fun-loving reputation: pain. Using sophisticated brain-scanning and a carefully controlled way of inducing muscle pain, the researchers show that the brain's dopamine system is highly active while someone experiences pain - and that this response varies between individuals in a way that relates directly to how the pain makes them feel.

Some philosophers, such as Jeremy BenthamBaruch Spinozaand Descarteshave hypothesized that the feelings of pain or suffering and pleasure are part of a continuum. There is strong evidence of biological connections between the neurochemical pathways used for the perception of both pain and pleasureas well as other psychological rewards. From a stimulus-response perspective, the perception of physical pain starts with the nociceptorsa type of physiological receptor that transmits neural signals to the brain when activated. These receptors are commonly found in the skin, membranes, deep fascias, mucosa, connective tissues of visceral organs, ligaments and articular capsules, muscles, tendons, periosteum, and arterial vessels.
Pain is usually such a negative experience that we rarely think about it in terms of just another sensory modality let alone consider the potential of positive aspects to it. Because of that, this post will be a bit unconventional, especially for a BiM blog. Based on E.
