Abstract

fetched live from OpenAlex

Abstract A central challenge for theories of memory is to understand how the brain prioritizes learning based on motivational relevance. Emerging findings indicate that the neurotransmitter dopamine plays a critical role in this process. Dopaminergic modulation links learning and memory to motivation and reward, thereby ensuring that memories are adaptive for future behavior. This chapter reviews the neural pathways and behavioral and cognitive consequences of this modulation, with a focus on two main dopaminergic targets: the striatum and the hippocampus. It reviews evidence regarding the neural and computational mechanisms by which dopamine reinforces learning of habits in the striatum and also the role of dopamine in modulating long-term episodic memories in the hippocampus. Understanding the effects of dopamine across multiple learning and memory systems helps resolve a fundamental challenge in memory research: explaining what humans learn, and why.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
