Innate odor preferences in C. elegans are controlled by the activation of a pair of olfactory sensory neurons. Here, the authors show that asymmetric activation of the AWCON and AWCO FF neurons can lead to irrational olfactory preferences that are explained by a model of normalization of sensory gain control.
