This study uses a computational model and machine learning to analyze monkey decision-making in risk-taking tasks, revealing dynamic optimism and pessimism states and a unique control rule for bias.

This study investigates the functional roles of the caudal orbitofrontal cortex (cOFC) and pregenual anterior cingulate cortex (pACC) in macaques using multimodal recordings and electrical microstimulation, finding distinct roles in decision-making and autonomic responses.

The paper develops a nontransgenic method using bridge proteins to target viral vectors to cells expressing endogenous μ-opioid receptors in mouse and monkey brains.

The paper develops a novel foraging task to study action-outcome associations in mice, revealing that striosomal neurons encode reinforcement outcomes more strongly than matrix neurons.

This study shows that microstimulation of specific prefrontal cortex regions in non-human primates induces negative decision-making by targeting striosomes in the anterior striatum.
