Wending between Faust and Wimsatt

Is neuroanthropology just “social theory with technical jargon,” giving us “street cred”?  Are we doing anything “different from interpretive anthropology with its system of symbols”?  Why invoke brain biology, we haven’t spent years studying the minutiae of brain circuitry and chemical interactions like real brain experts.  Why even bother with the mention of neurotransmitters and such, which bastardizes the rich contribution that anthropology makes to understanding ourselves. 

These are some of the comments I’ve seen about our site, some on the Internet, some in emails.  In an initial answer to that, I pointed to Greg’s introduction, of listening to our informants and building explanations based on ethnography as well as to some of the limitations we bump up against in the dominant forms of social theory today.

Visual Rewards

Blogging on Peer-Reviewed ResearchWhy will we study a favored painting again and again?  Or gaze on our lover’s face with such pleasure, even after years and lines have mounted?

 I came across an article, “Perceptual Pleasure and the Brain,” by Irving Biederman and Edward Vessel in American Scientist.  They studied the distribution of mu-opioid receptors, associated with the modulation of pleasure and pain, in the visual cortex.  Their basic result: “The receptors are sparsest in the early stages of this [central visual] pathway, the so-called V1 to V4 areas, where an image is processed as local bits of contour, color and texture.  Intermediate stages of visual processing, such as the lateral occipital area and ventral occipito-temporal cortex, which integrate local information to detect surfaces, objects, faces and places, contain greater number of opioid receptors.  The receptors are densest in the later stages of recognition, in the parahippocampal cortex and rhinal cortex, where visual information engages our memories.”

 Thus, they argue, “a visual stimulus that elicits many episodic or semantic memories should be more pleasing (or more interesting) than a stimulus that brings forth fewer mental associations.”
