Searching for anatomical correlates of olfactory lateralization in the honeybee antennal lobes: A morphological and behavioural study

► Olfactory lateralization in the honeybee brain is investigated. ► Volumes of antennal lobe's glomeruli are compared between brain hemispheres. ► Memory recall is tested after single antenna conditioning to different odour classes. ► No asymmetries in glomerular volumes are found. ► Asymmetry of recall performance depends on the biological relevance of the compounds.
