This study shows that long-term learning shifts information processing from the ventral striatum to the orbitofrontal cortex in macaques, challenging traditional theories of reinforcement learning.

This study investigates how ventral frontostriatal circuitry processes symbolic gains and losses in monkeys, identifying the role of the orbitofrontal cortex in coding outcomes and prediction errors.

The paper introduces a convolutional neural network to estimate synaptic connectivity from spike trains without requiring parameter tuning, and applies it to construct neuronal circuit diagrams in monkey cortical areas.

This study examines how learning affects neural population activity dimensionality and information about choices in the prefrontal cortex using high channel count recordings in monkeys.
