This study investigates the role of fast-spiking neurons in working memory tasks, finding they generate persistent activity and predict recall as effectively as regular-spiking neurons.

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 shows that working memory in the prefrontal cortex involves both persistent activity and activity-silent dynamics, with reactivation of latent traces enhancing serial biases in spatial memory.

The paper investigates whether prefrontal and parietal cortex activity predicts categorical working memory judgments and finds that both areas show firing rate deviations linked to memory content and performance.
