The paper investigates how serotonergic and GABAergic neurons in the dorsal raphe nucleus contribute to effort-based decision-making by analyzing their activity during a task.

This study identifies the role of dorsal raphe nucleus neurons in stress-induced shifts from goal-directed to habit-driven behavior using mouse models and molecular profiling.

This study examines age-related changes in neural and behavioural variability during a decision-making task in mice, finding increased neural variability and reduced variability quenching in specific brain regions.

The paper presents a brain-wide neural activity map from 621,733 neurons across 139 mice performing a decision-making task, showing how neural activity encodes task variables across brain regions.

The paper investigates how direct and indirect basal ganglia pathways influence cortical activity during decision-making, finding that they oppositely modulate a subset of neurons encoding decision variables.

The paper shows that postingestive malaise signals reactivate amygdala flavor representations, strengthening memory and resolving temporal credit assignment in aversive learning.

This study shows that increasing 2-AG levels reduces opioid reward but not analgesia in mice, suggesting a potential therapeutic strategy for pain treatment.

The paper identifies epigenetically bistable regions in neuronal genes that influence neuronal eligibility for coding ensembles in the hippocampus, showing their role in spatial memory and excitability.

This study identifies stress-responsive neurons in the lateral septum that reduce food intake and body weight through hypothalamic pathways.
