Abstract

Dopaminergic signaling in the nucleus accumbens (NAc) is central to reward-based learning, but its relationship to brain-wide hemodynamics remains unclear. Using concurrent fMRI and dopamine photometry in awake, behaving mice, we reveal that associative learning induces a gradual temporal shift in NAc blood oxygenation responses that mirrors dopamine release dynamics. This shift emerges with cue-reward learning and extends across a distributed network encompassing the lateral septal complex, as well as prefrontal, insular, and hypothalamic regions. Further, dopamine transients tightly correspond with local blood oxygenation level dependent (BOLD) signals, and variations in reward value modulate delayed BOLD responses in both the NAc and additional subcortical structures. Regressing out the measured dopaminergic signal abolishes this reward-related modulation, suggesting that BOLD signals track dopaminergic reward prediction. These findings reveal a close relationship between dopamine signaling and widespread changes in brain activity during learning.

Code

No file of the authors' code could be read here: it is described below, and read at its source.

The paper's code and data availability statement is in the Data section.

Tracing map

Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.

What the map holds:

• 1 repository of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
• 0 scripts, each with its path and the digest of its content;
• no match between paragraphs and code yet;
• neither the text of the paper nor the code itself.

Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.
