The paper introduces an integrated Ising model with global inhibition to explain decision-making, showing it can improve accuracy and has unique learning properties.

This study shows sleep reduces negative emotional generalization and enhances positive generalization, with neural correlates involving amygdala activity and sleep-spindle activity.

The paper shows that GABA in the dACC affects appetitive and aversive learning through distinct mechanisms involving different brain regions and connectivity patterns.

The paper develops an automatic system for coding macaque facial expressions, achieving high performance in recognizing six AUs across species.

The paper investigates how emotion affects neural similarity between pictures and perceived similarity, finding increased neural similarity in specific brain regions for emotional stimuli, but no change in perceived similarity ratings.

The paper shows that dopamine levels affect beta oscillation frequency, not power or coherence, in cortico-basal ganglia networks of NHPs and PD patients.

The paper shows that higher trait anxiety increases exploration in a decision-making task, which harms performance due to a tradeoff between uncertainty reduction and value gains.

The paper tracks neural dynamics during learning in primate brain regions using a geometric framework, revealing differential roles of dACC and striatum in behavior adaptation.

This study shows that targeted memory reactivation during sleep improves memory for specific words associated with local brain activity, modulating slow wave activity in the cued hemisphere.

The paper shows that prediction-errors bias time perception by altering perceived duration, with positive errors increasing and negative errors decreasing perceived time.

The paper shows that prestimulus activity in the cingulo-opercular network predicts memory for naturalistic episodic experiences by modulating encoding and retrieval processes.

The paper investigates neural coding for eye-gaze and valence in monkeys, finding shared circuits and coding mechanisms between gaze and reward/punishment signals.

The paper shows that primate amygdala neurons signal specific periods during the inter-trial-interval, supporting aversive learning and suggesting a shared circuit for maintaining temporal contingencies.

This study investigates inhibitory and excitatory mechanisms in the human dorsal anterior cingulate cortex during reinforcement learning and finds that GABA levels correlate with learning performance.

This study investigates how theta oscillations synchronize amygdala-to-prefrontal circuits during aversive learning and finds that synchrony declines once memory stabilizes.
