Abstract

When an odour activates a fly′s antennae asymmetrically, more neurotransmitter is released from olfactory receptor neuron axon branches ipsilateral to the antenna than from contralateral branches. This causes ipsilateral central olfactory neurons to begin spiking earlier and at a higher rate than contralateral neurons, thereby enabling a walking fly to turn towards the odour.
