One of the strengths of this article was the testing of both scent detection and scent discrimination. Olfactory cues are more complex in nature than what can normally be reconstructed in a lab. Therefore, the authors’ decided to drive home the hypothesis of olfactory lateralization by testing bees on two different aspects of olfaction.
One weakness of this study was that during the comparison of olfactory receptor cells each of the 10 pairs of antennae should have come from 10 individuals. Instead, only 7 pairs came from 7 individuals and the other three from three individuals. This could cause some data discrepancies because all antennae were not collected in the same manner. Also, 10 pairs of antennae is not a high number considering they added this information to their paper. The authors might want to gather more data with more pairs of antennae in order to be entirely sure of the correlations.
