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...

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 information in their functional units, the glomeruli.

Using multidimensional analysis, we show that clustering of odours is similar in ants, bees and rats.
