Scientists find brain cells that know which end is up Johns Hopkins University

In a new study, scientists have found the brain cells apparently responsible for this innate wisdom. In a part of the brain responsible for recognizing color, texture and shape, Johns Hopkins University researchers found neurons that used large-scale environmental cues to infer the direction of gravity. The findings, forthcoming this month in the journal Current Biology, and just posted online, suggest these cells help humans orient themselves and predict how objects will behave. “Gravity is a strong ubiquitous force in our world,”…
