Quantitative analysis of sex pheromone coding in the antennal lobe of the moth Agrotis ipsilon: a tool to study network plasticity
... To find a mating partner, moths rely on pheromone communication. Released in very low amounts, female sex pheromones are used by males to identify and localize females. Depending on the physiological state (i.e. age, ...
