Funding Opportunities Number
Project Number
Many animals rely on their ability to navigate to the source of airborne odor plumes for survival. Studies dating back a century have shown that insects combine mechanosensory and olfactory cues to navigate, surging upwind when detecting odor but go crosswind or downwind when losing the signal.
