Abstract

Here, we combined MRI ‐guided electrical microstimulation and viral tracing to examine the function of a corticostriatal circuit implicated by previous cortical microstimulation as modulating affective judgment and decision‐making. Local microstimulation of a small part of the pregenual anterior cingulate cortex ( pACC ) was found to increase avoidance decisions in a cost‐benefit decision‐making task (Ap‐Av task) in which differing amounts of “good” and “bad” options were given simultaneously. No effect of such stimulation was found when the monkeys performed a task in which both offers were rewarding, but given in different amounts. We asked whether we could identify the targets of such corticostriatal circuits when the cortical microstimulation sites were explicitly identified as affecting approach or avoidance in the Ap‐Av task. We explored the pACC and caudal orbitofrontal cortex ( cOFC ) to look for such sites. For each cortical region, we found sites at which microstimulation induced increased avoidance behavior. After identifying these sites, we injected viral tracers carrying constructs allowing subsequent track‐tracing post‐mortem. For each site identified behaviorally as increasing avoidance choices, we found strong fiber projections to the anterior striatum with large parts of these targeting striosomes subsequently identified by serial section immunohistochemistry. With fMRI , we demonstrated that microstimulation in an anesthetized monkey at sites pre‐identified as affecting Ap‐Av choices induced blood oxygen level dependent activation of the anterior striatum, confirming that the microstimulation method that we applied was effective in activating the striatum. These findings outline circuits leading from pACC / cOFC to striosomes and causally modulating decision‐making under emotional conflict.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Stimulation of the striosomes of the striatum to which the pgACC region projects induces a negative bias.

    “stimulation of the striosomes of the striatum to which this region projects also induces a negative bias [202]”

    From Prefrontal cortex and depression (2022) · cites this paper as [202]

    The Results report that microstimulation of pACC sites increased avoidance choices and that those sites preferentially projected to striosomes. The paper stimulated the cortex, not the striosomes directly, so it does not establish that stimulation of striosomes induces the negative bias. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
