Efficient and dynamic neural geometry of value and modality encoding in the primate putamen for value-guided behavior.

ABSTRACT: The basal ganglia process diverse reward values from various modalities using limited resources, necessitating efficient processing. The convergence of sensory reward values at the single-neuron level enables the efficient use of limited neural resources. However, this raises a critical question: does such convergence compromise modality-specific information and degrade the overall information quality? Here, we reveal that the population representation of bimodal value neurons in the macaque putamen, which converges value information from tactile and visual inputs, efficiently preserves both value and modality information through shared abstract representations. These population representations generalized across identical modalities and values, establishing and maintaining an efficient lo
