Abstract Primates must adapt to changing environments by optimizing their behavior to make beneficial choices. At the core of adaptive behavior is the orbitofrontal cortex (OFC) of the brain, which updates choice value through direct experience or kn

Recent advancements in chemogenetic tools, such as designer receptors exclusively activated by designer drugs (DREADDs), allow the simultaneous manipulation of activity over a specific, broad brain region in nonhuman primates. However, the introducti

Pharmacological and surgical treatments of epilepsy can have unsatisfactory outcomes, so a more targeted and on-demand approach is desirable. Here, the authors demonstrate the usage of inhibitory chemogenetics in male nonhuman primates to attenuate t

The term ‘temporal discounting’ describes both choice preferences and motivation for delayed rewards. Here we show that neuronal activity in the dorsal part of the primate caudate head (dCDh) signals the temporally discounted value needed to comp
