Reward revaluation and hippocampal replay content

Takeaway

  • Sharp-wave ripple (SWR) content can relate to experience and reward revaluation but is not limited to reflecting recent experience or trajectories toward the preferred goal.

Why this matters

  • Goal-directed bias in hippocampal SWRs predicts content favors the highly valued outcome; this work suggests SWR content does not favor recent experience or the preferred choice in reward revaluation.
