Abstract
It is not yet clear how dorsal hippocampal rhythms contribute specific information that impacts future behavior. Using a spatial set-shifting task that requires animals to behave flexibly and continuously adapt to different spatial strategies, we found that beta power increased after incorrect choices. Higher beta and gamma power after reward feedback was linked with greater accuracy on the next trial, scaling with rhythm power. These results highlight the importance of relating hippocampal rhythms to multiple within-trial segments to better understand how individual rhythms may differentially support future behaviors.
