Calcium imaging in the ant Camponotus fellah reveals a conserved odour-similarity space in insects and mammals

Background: Olfactory systems create representations of the chemical world in the animal brain. Recordings of odour-evoked activity in the primary olfactory centres of vertebrates and insects have suggested similar rules for odour processing, in particular through spatial organization of chemical in...
