The paper shows nicotine inhibits amygdala-projecting dopamine neurons via a VTA-NAc feedback loop, leading to anxiety.

The paper studies individual differences in reward-seeking behavior among isogenic mice in a social environment and links these differences to nicotine response and dopaminergic adaptability.

This study identifies distinct dopamine circuits in the ventral tegmental area that mediate nicotine's reinforcing and anxiogenic effects through opposing responses in neurons projecting to the nucleus accumbens and amygdala.

The paper shows that social interactions shape individuality in mice by altering dopaminergic system adaptations and behavioral traits.
