The Demise of Guys

From a discussion about the new American Society of Addiction Medicine definition of addiction comes this 5-minute long humorous, albeit somewhat alarming, video clip providing insight on “the dopamine hypothesis.” Currently, few people realize that the dopamine hypothesis is merely an underdeveloped explanation of neurophysiological cause and effect because no associated environmental stimulus directly effects a neuroendocrine response which links the stimulus to behavior. People think that visual input directly effects dopamine, but no evidence suggests a neurophysiological mechanism that would allow this direct effect. Most of the visitors here will probably need to wait until other researchers learn its the link from food odors and social odors (i.e., pheromones) that gives the dopamine hypothesis its credibility via the effect of odors on a cascade of hormones that begins with gonadotropin releasing hormone (GnRH). But until then, you can still enjoy the video.
