Abstract

The brain reward circuit has a central role in reinforcing behaviors that are rewarding and preventing behaviors that lead to punishment. Recent work has shown that the lateral habenula is an important part of the reward circuit by providing 'negative value' signals to the dopaminergic and serotonergic systems. Studies have also suggested that dysfunction of the lateral habenula is associated with psychiatric disorders, including major depression. Here, we discuss insights gained from neuronal recordings in monkeys regarding how the lateral habenula processes reward-related information. We then highlight recent optogenetic experiments in rodents addressing normal and abnormal functions of the habenula. Finally, we discuss how deregulation of the lateral habenula may be involved in depressive behaviors.

  • Over-activation of the lateral habenula has been proposed to be involved in depression and as a site of antidepressant action of conventional antidepressant drugs.

    “The lateral habenula signals negative valence to monoaminergic systems and over-activation of the lateral habenula has recently been proposed to be involved in depression as well as to be a site of antidepressant action of conventional antidepressant drugs (Proulx et al., 2014; Sartorius and Henn, 2007).”

    The ‘Lateral habenula in depressive disorders’ section says LHb hyperactivity may contribute to depression. It also reports that chronic antidepressant treatment altered inputs to LHb neurons, but the available passage cuts off before describing the full result; the Conclusions propose pharmacological reduction of LHb hyperactivity as a future opportunity. These passages do not establish that the LHb is a site of action of conventional antidepressant drugs. (LLM, conf=0.82)

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.
