Delighted to share our work on replay and successor representations! We find replay during very short task pauses in human visual cortex that is linked to learning SRs & happens when learning is implicit. Study led by @lnnrtwttkhn.bsky.social

Interesting connection! Thanks so much for sharing your new paper.

Thanks so much, Paul. That is a good point!

Thanks! And thank you, I’ve found your results there to be very intriguing, too.

Overall, the results challenge the idea that motivational symptoms universally impair decision-making.

In the paper, we discuss potential reasons for this surprising finding.

We are very happy to hear your thoughts, and please share!

…but in actual decision-making, they showed enhanced goal-directed performance:

Higher apathy-anhedonia scores were related to greater sensitivity to goal values – plus faster navigation to goals and higher earnings.

(n.b. this relationship was not found in other common tasks we also collected.)

We tested links to transdiagnostic psychiatric symptoms.

The relationships with an 'Apathy–Anhedonia' factor were very interesting: people with higher scores reported lower expectations of goal success...

The paradigm tries to capture features of real-world decision-making:
1) we often make choices in well-learned envirornments,
2) risk is learned from experience, and
3) plans with more steps are riskier, but can also be more rewarding

We designed a novel risky goal task: over two days, participants learned maze-like environments where each step carried a small risk of failure. As goals became more distant, risk compounded.

Participants then made choices between a certain reward vs. risky goals with variable distance & reward.

🧵 New paper! We studied depression symptoms and goal-directed decisions under uncertainty

Surprisingly, we found that apathy–anhedonia was linked to enhanced goal-directed behavior. www.biorxiv.org/content/10.1...

Epic dopamine / VTA neuron diversity paper

Across 3 studies (1 preregistered), combined n>600, using 2 different RL tasks, we found that performance was positively correlated with anhedonia symptoms.

General depression effects were mixed, but no correlations were negative.

These results are unexpected so we look forward to feedback!

Reconstructing a new hippocampal engram for systems reconsolidation and remote memory updating This study demonstrates that hippocampal activity during remote recall is crucial for the reconsolidation of remote memory, also called systems reconsolidation, with new hippocampal engram cells recruited to enable memory updating. The findings reveal that adult neurogenesis supports this recruitment process and the role of mPFC projections to the hippocampus and amygdala in systems reconsolidation.
