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 identifies a distributed frontal cortical circuit associated with behavioral flexibility in macaques through structural and functional imaging analyses of discrimination reversal learning.

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.

This study investigates how macaque monkeys maintain and translate counterfactual choice values into behavioral changes using functional MRI and ultrasound disruption of the anterior cingulate cortex.
