Apathy-anhedonia is associated with pessimistic beliefs yet sharpened goal-directed planning

The paper shows that apathy-anhedonia is linked to pessimistic beliefs but not reduced goal-directed planning, with enhanced performance in value-based decision-making tasks.

Distinct replay signatures for prospective decision-making and memory preservation

The paper investigates distinct neural replay signatures during decision-making and memory preservation in humans using MEG and multivariate analysis.

Reward learning and working memory: effects of massed versus spaced training and post-learning delay period

This study compares massed and spaced training in reward-based learning, finding that spaced training reduces working memory contributions and isolates gradual learning mechanisms.

Reactivation of single-episode pain patterns in the hippocampus and decision making

The paper shows that single aversive experiences influence decision making and that hippocampal reactivation of pain-related patterns is linked to better memory performance.

Episodic memory retrieval success is associated with rapid replay of episode content

The paper shows that successful retrieval of episodic memories involves compressed sequential replay of memory elements, which direction depends on task goals.

Learning of distant state predictions by the orbitofrontal cortex in humans

This study uses fMRI to show that the OFC-VPFC represents predictive information about upcoming states up to 30 seconds in the future during goal-directed learning.

Reward learning over weeks versus minutes increases the neural representation of value in the human brain

This study compares spaced versus massed reward learning in humans, finding that spaced learning leads to better long-term memory of value associations.

Reactivation of reward-related patterns from single past episodes supports memory-based decision making

The paper shows that reactivating reward-related neural patterns from single past episodes influences memory-based decision making and financial risk-taking.

Pain to remember: a single incidental association with pain leads to increased memory for neutral items one year later

This study shows that pairing neutral items with pain enhances memory for those items one year later, with neural correlates in the insula.
