An 18-inch-long dead salmon showed activity along the midline of its brain when it was shown photos of humans in social settings, according to a neuroimaging study led by Craig Bennett, a postdoctoral researcher in psychology at the University of California at Santa Barbara. The point of the study was to show that false positives are commonplace in neuroimaging research.
“The salmon was shown a series of photographs depicting human individuals in social situations with a specified emotional valence,” the researchers reported. “The salmon was asked to determine what emotion the individual in the photo must have been experiencing.”
Also scanned but without result: a pumpkin and a Cornish hen, also dead. –Don Troop
