Abstract

Atypical habituation and aberrant exploration of novel stimuli have been related to the severity of autism spectrum disorders (ASDs), but the underlying neuronal circuits are unknown. Here we show that chemogenetic inhibition of dopamine (DA) neurons of the ventral tegmental area (VTA) attenuates exploration toward nonfamiliar conspecifics and interferes with the reinforcing properties of nonfamiliar conspecific interaction in mice. Exploration of nonfamiliar stimuli is associated with the insertion of GluA2-lacking AMPA receptors at excitatory synapses on VTA DA neurons. These synaptic adaptations persist upon repeated exposure to social stimuli and sustain conspecific interaction. Global or VTA DA neuron-specific loss of the ASD-associated synaptic adhesion molecule neuroligin 3 alters the behavioral response toward nonfamiliar conspecifics and the reinforcing properties of conspecific interaction. These behavioral deficits are accompanied by an aberrant expression of AMPA receptors and an occlusion of synaptic plasticity. Altogether, these findings link impaired exploration of nonfamiliar conspecifics to VTA DA neuron dysfunction in mice.

  • 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).”

    In Results > VTA DA neurons and nonfamiliar conspecific reinforcement (page unavailable), reducing VTA dopamine-neuron excitability prevented mice from developing a conditioned preference for a compartment associated with nonfamiliar conspecifics. This supports a role for these neurons in social reinforcement learning, but does not establish that increasing their activity promotes that learning. (LLM, conf=0.83)

  • Dopaminergic neurons of the VTA that project to the NAc play a pivotal role in regulating both social cues and reward processing in both humans and rodents.

    “Dopaminergic neurons of the VTA, which extend their projections to the nucleus accumbens (NAc), play a pivotal role in regulating both social cues and reward processing in both humans and rodents (Bariselli et al., 2018; Gunaydin et al., 2014, 2014; Kawamichi et al., 2016).”

    From Convergence of oxytocin and dopamine signalling in neuronal circuits: Insights into the neurobiology of social interactions across species (2024) · cites this paper as Bariselli et al., 2018

    The Discussion (page unavailable) says VTA dopamine neurons projecting to the NAc promote conspecific interaction and places projection-specific VTA neurons within reward circuitry. The Introduction and Results describe social exploration and reinforcement in rodents, but the paper does not establish that the VTA-to-NAc projection regulates social cues and reward processing in humans.

  • DA neurons in the VTA play a role in social behavior.

    “Previous studies have indicated the role of DA neurons in the VTA in social behavior (Gunaydin et al., 2014; Bariselli et al., 2018; Bariselli et al., 2016b) and shown that chronic isolation alters DA levels in the NAc (Hall et al., 1998; ).”

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.
