Reconstitution en 3D d’un cerveau d’abeille mellifère (Apis mellifera). Ce modèle a été obtenu à partir d’un scan par microtomographie à rayons X (micro-CT). Les fausses couleurs délimitent des aires cérébrales fonctionnelles bien définies (jaune : lobes visuels, violet : lobes olfactifs, rouge : corps pédonculés, bleu : complexe central).
Does a larger brain make you smarter? The question of brain size and cognitive ability is as old as time, and contrary to popular belief, a larger brain does not necessarily mean better cognitive performance.
The team led by Mathieu Lihoreau, Coline Monchanin, Tamara Gómez Moracho, Cristian Pasquaretta, Louise Bestea, Jean-Marc Devaud (CRCA-CBI), together with their collaborators, has provided a nuanced answer when it comes to bees. By testing their ability to associate smells with a reward, the scientists have shown that individuals with more developed olfactory lobes learn better. This ability could improve their foraging efficiency.
