Longitudinal tracking of mice reveals that stable, specialized social roles emerge spontaneously within groups during a foraging task, with dopaminergic activity in the ventral tegmental area driving ...

Nature Neuroscience - Bergel et al. show that an infraslow rhythm connecting the brain and body during sleep is shared by lizards, mammals and birds, revealing an ancestral process and reshaping...

Drugs of abuse exert both motivational and emotional effects. Here, the authors show that nicotine and ethanol activate a VTA–NAc loop that inhibits dopamine neurons projecting to the amygdala, thereb...

In this issue of Neuron, Jehl et al. developed a “suicide” antagonist to demonstrate that the interpeduncular nucleus acts as a regulatory controller of nicotine reward-related behavior through connec...

Body ownership disorders can be triggered by disease or body damage in humans. This study shows, using an automated, videography-based procedure, that mice also display quantifiable behavioral markers...

In the dorsomedial striatum, d-SPNs increase risk seeking, while iSPNs amplify the value of large gains in decision making.

Nature Neuroscience - The developmental origin of behavioral individuality is unclear. The authors show that a temporal sequence of genetically encoded stochastic mechanisms explains variation in...

Nicotine activates the dopamine reward system to promote consumption and addiction, but the brain has a natural brake to counteract it. Jehl, Ciscato, Vicq, Guyon, et al. identified the interpeduncula...

Social organization and division of labor are fundamental to animal societies, but how do these structures emerge from individual interactions, and what role does neuromodulation play in shaping them?...

The reason why manipulating dopamine (DA) activity can affect both action latency, action direction, and movement vigor, but only in certain animal states and behavioral settings is not fully understo...

Rabah et al. discover an astrocyte-to-neuron hydrogen peroxide signalling cascade, which is crucial for long-term memory formation in Drosophila. This signalling is found to be inhibited by amyloid-β ...

La dopamine, une molécule clé dans le cerveau, est essentielle à l’

The reason why manipulating dopamine (DA) activity can affect both action latency, action direction, and movement vigor, but only in certain animal states and behavioral settings is not fully understo...

How nicotine impacts the adolescent development of neural circuitry is not fully understood. Here authors show that early adolescent nicotine exposure in male mice blocked the maturation of nicotine-e...
