Neurobiology: Scent secrets of insects

Rachel I. Wilson1

Top

The perception of carbon dioxide provides insects with sensory data on their environment, and informs many insect behaviours. It seems that this sense relies on two dedicated neural receptors.

We inhabit a different sensory universe from that of many of the animals around us. We are deaf to high-pitched sounds that dogs perceive, blind to ultraviolet light that honeybees see, and numb to electric fields that sharks feel.
