[modified] In the early 1980s, Michael Lewis at the National Institute of Mental Health and his colleagues discovered mu-opioid receptors in a part of the macaque monkey cerebral cortex that is involved in processing visual information. The receptors are distributed in a gradient that gradually increases in density along the so-called ventral visual pathway, which is involved in the recognition of an object or a scene. Subsequent work has found evidence for a similar gradient in the homologous human areas. The receptors are sparsest in the early stages of this 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 numbers 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
