Fig. S1. Latency to sting and biogenic amine levels, continued from Fig. 3. from Cooperative defence operates by social modulation of biogenic amine levels in the honeybee brain

Latency to sting of individual bees plotted against their level of a. OA in the central brain, b. OA in the optic lobes, c. OA in the sub-esophageal zone, d. DA in the central brain, e. DA in the sub-esophageal zone, f. 5HT in the optic lobes. (n=54 bees).
