Abstract: | The level of conditioned behavior in animals is proportional to the intensity, amount, frequency, or probability of reinforcement.
Interestingly, this matching can be dynamic, with performance levels following, for example, a switch in the probability of
reinforcement with a short delay. We previously found that conditioned performance levels in Drosophila match reinforcement intensity in a place conditioning paradigm. Whether Drosophila can match conditioned behavior to a change in reinforcement intensity was an open question. In this study, we found that
both conditioned behavior and memory levels match reinforcement intensity after a switch, and this rapid matching occurs within
2 min. Thus, fruit flies can dynamically match conditioned behavior and memory levels to a change in reinforcement intensity. |
