The paper identifies the frontal eye field (FEF) as leading a distributed circuit for abstract categorical decisions by analyzing neural activity in monkeys during a visual motion-categorization task.

The paper shows that diverse neuronal firing rates reduce the dimensionality of trial-to-trial covariability in population responses across multiple species.

This study identifies a novel role of the primate superior colliculus in abstract visual categorization, showing it encodes category information more strongly and quickly than the posterior parietal cortex.

This study investigates the roles of prefrontal and parietal cortices in sequential categorical decisions using neural recordings and computational models.

The paper investigates how neuronal encoding and population dynamics in parietal cortex support different categorization tasks, finding that encoding styles vary between tasks and that RNNs support the hypothesis of binary-like encoding through attractor dynamics.
