Experiments at Manchester University have led to two major claims: (1) in solving problems of orientation and navigation, humans have access to some non-visual ability; and (2) at least in part, this non-visual ability involves magneto-reception. This stark contrast between positive results and negative interpretations remains an unexplained feature of the literature on human magneto-reception. Spine is faded otherwise in good to very good condition. Personal dedication by the author is on the inside.
