Sleep-dependent infraslow rhythms are evolutionarily conserved across reptiles and mammals
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...

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

Nicotine and alcohol seem very different, but they converge on the same circuit. Both activate NAc-projecting dopamine neurons and inhibit those projecting to the amygdala. We show that this shared loop shapes reward and emotion, helping explain their high co-use.
July 5, 2025 at 1:19 PM
A circuit-level explanation for nicotine’s dual impact: Nicotine activates VTA→NAc dopamine neurons (reward), but this comes at a cost: It triggers a GABAergic feedback loop that inhibits VTA→amygdala neurons (emotion).
One drug, the dopaminergic circuits, 2 effects: reinforcement + negative affect.
July 5, 2025 at 1:19 PM
Nicotine doesn’t just “turn on” the brain’s reward circuits — it reshapes them. Our new paper in Nature Communications shows that activating reward-linked dopamine neurons also sets off a feedback loop that drives negative emotional states.

Nouvel article avec mes ami-es belges E. Chaves et A. de Kerchove où on décrit l'effet de l'activation de populations de neurones du striatum sur les stratégies de décision. On a essayé de sortir d'une définition "par l'expérimentateur" de la performance des souris.

Direct and indirect striatal projecting neurons exert strategy-dependent effects on decision-making
In the dorsomedial striatum, d-SPNs increase risk seeking, while iSPNs amplify the value of large gains in decision making.

Social structures are dynamic: manipulating dopamine activity reshapes role distribution, confirming a feedback loop where social context modulates neural states, which in turn reinforce specialization.
