Interplay between persistent activity and activity-silent dynamics in the prefrontal cortex underlies serial biases in working memory
Persistent neuronal spiking has long been considered the mechanism underlying working
memory, but recent proposals argue for alternative 'activity-silent'substrates. Using monkey …

Spatiotemporal transformations for gaze control
Sensorimotor transformations require spatiotemporal coordination of signals, that is, through
both time and space. For example, the gaze control system employs signals that are time …
