Comment on “Food wanting is mediated by transient activation of dopaminergic signaling in the honey bee brain”

Huang et al. (1) make an exciting claim about a human-like dopamine-regulated neuromodulatory mechanism underlying food-seeking behavior in honey bees. Their claim is based on experiments designed to measure brain biogenic amine levels and manipulate receptor activity. We have concerns that need to be addressed before broad acceptance of their results and the interpretation provided.
