Neural circuit models for evidence accumulation through choice-selective sequences

The paper develops two neural circuit models for evidence accumulation through sequential neuronal activity and tests them against neural recordings from four brain regions during a decision-making task.

Striatal pathways oppositely shift cortical activity along the decision axis

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.

A neural mechanism for learning from delayed postingestive feedback

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

Opponent control of behavior by dorsomedial striatal pathways depends on task demands and internal state

The paper shows that dorsomedial striatal pathways oppositely control behavior depending on task demands and internal state.

Cholinergic interneurons mediate cocaine extinction through similar plasticity across medium spiny neuron subtypes

The paper shows that endogenous acetylcholine signaling in the nucleus accumbens mediates cocaine extinction by modulating synaptic strength similarly across medium spiny neuron subtypes.

Prelimbic-dependent activation of amygdala somatostatin interneurons signals non-aversive cues to promote discrimination.

This study shows that prelimbic cortex-dependent activation of basolateral amygdala somatostatin interneurons promotes discrimination of non-threatening stimuli by blocking theta-oscillation phase resetting.
