Bees do not normally learn to discriminate between odor mixtures with a dominant odor but habituating the bees to the dominant odor greatly improves performance

Color modulates olfactory learning in honeybees by an occasion-setting mechanism.
A sophisticated form of nonelemental learning is provided by occasion setting. In this paradigm, animals learn to disambiguate an uncertain conditioned stimulus using alternative stimuli that do not enter into direct association with the unconditioned stimulus. For instance, animals may learn to discriminate odor rewarded from odor nonrewarded trials if these two situations are indicated by dif...
متن کاملSide-specific olfactory conditioning leads to more specific odor representation between sides but not within sides in the honeybee antennal lobes
Honeybees can be trained to associate odorants to sucrose reward by conditioning the proboscis extension response. Using this paradigm, we have recently shown that bees can solve a side-specific task: they learn simultaneously to discriminate a reinforced odor A from a non-reinforced odor B at one antenna (A+B-) and the reversed problem at the other antenna (A-B+). Side-specific (A+B-/B+A-) con...
متن کاملWalking patterns induced by learned odors in the honeybee, Apis mellifera L.
The odor localization strategy induced by odors learned via differential conditioning of the proboscis extension response was investigated in honeybees. In response to reward-associated but not non-reward-associated odors, learners walked longer paths than non-learners and control bees. When orange odor reward association was learned, the path length and the body turn angles were small during o...
متن کاملOlfactory Interference during Inhibitory Backward Pairing in Honey Bees
BACKGROUND Restrained worker honey bees are a valuable model for studying the behavioral and neural bases of olfactory plasticity. The proboscis extension response (PER; the proboscis is the mouthpart of honey bees) is released in response to sucrose stimulation. If sucrose stimulation is preceded one or a few times by an odor (forward pairing), the bee will form a memory for this association, ...
متن کاملSuccessive olfactory reversal learning in honeybees.
Honeybees Apis mellifera can associate an originally neutral odor with a reinforcement of sucrose solution. Forward pairings of odor and reinforcement enable the odor to release the proboscis extension reflex in consecutive tests. Bees can also be conditioned differentially: They learn to respond to a reinforced odor and not to a nonreinforced one. They can also learn to reverse their choice. H...
