dc.description.abstract
We asked whether and how a sequence of a honeybee's experience with different
reward magnitudes changes its subsequent unconditioned proboscis extension
response (PER) to sucrose stimulation of the antennae, 24 hours after
training, in the absence of reward, and under otherwise similar circumstances.
We found that the bees that had experienced an increasing reward schedule
extended their probosces earlier and during longer periods in comparison to
bees that had experienced either decreasing or constant reward schedules, and
that these effects at a later time depend upon the activation of memories
formed on the basis of a specific property of the experienced reward, namely,
that its magnitude increased over time. An anticipatory response to reward is
typically thought of as being rooted in a subject's expectations of reward.
Therefore our results make us wonder to what extent a long-term ‘anticipatory’
adjustment of a honeybee's PER is based upon an expectation of reward. Further
experiments will aim to elucidate the neural substrates underlying reward
anticipation in harnessed honeybees.
