Abstract

Social interactions are motivated behaviors that, in many species, facilitate learning. However, how the brain encodes the reinforcing properties of social interactions remains unclear. In this study, using in vivo recording in freely moving mice, we show that dopamine (DA) neurons of the ventral tegmental area (VTA) increase their activity during interactions with an unfamiliar conspecific and display heterogeneous responses. Using a social instrumental task, we then show that VTA DA neuron activity encodes social prediction error and drives social reinforcement learning. Thus, our findings suggest that VTA DA neurons are a neural substrate for a social learning signal that drives motivated behavior.

  • VTA dopaminergic neurons become activated in rodents engaged in conspecific interactions.

    “Specifically, research has demonstrated that VTA dopaminergic neurons become activated in rodents engaged in conspecific interactions, and increased activity in these neurons promotes social reinforcement learning (Bariselli et al., 2018; D ¨ olen et al., 2013; Soli ´ e et al., 2022).”
  • Increased activity in VTA dopaminergic neurons promotes social reinforcement learning.

    “Specifically, research has demonstrated that VTA dopaminergic neurons become activated in rodents engaged in conspecific interactions, and increased activity in these neurons promotes social reinforcement learning (Bariselli et al., 2018; D ¨ olen et al., 2013; Soli ´ e et al., 2022).”
  • VTA dopamine activity increased during lever pressing in a social instrumental operant task and optogenetic inhibition of VTA dopamine neurons impaired social reinforcement learning.

    “Consistent with an involvement of DA in the reinforcing properties of a social interaction, VTA DA activity increased during lever pressing in a social instrumental operant task and optogenetic inhibition of VTA DA neurons impaired social reinforcement learning [57].”

  • Dopamine neurons of the ventral tegmental area are necessary and sufficient to promote social interaction.

    “Recent studies have highlighted the necessity and sufficiency of dopamine (DA) neurons of the ventral tegmental area (VTA) to promote social interaction (Gunaydin et al., 2014; Solié et al., 2022).”

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.
