(University of Pennsylvania) Using varying combinations of banana and pine scents, University of Pennsylvania professor Jay Gottfried discovered that three key brain regions help humans navigate from one odor to the next. The work points to the existence of a grid-like hexagonal architecture in the olfactory brain, similar to mapping configurations previously found to support spatial navigation in animals.
