Scholars have long theorized a role for reactivation and rehearsal in maintaining items in memory. Recent evidence suggests that reactivation during awake rest or sleep predicts subsequent recognition and cued recall performance. In a free recall task however, the relationship between covert reinstatement and recall may be more complex because the memory cues must be self-generated and retrieval depends strongly on what has previously been retrieved. Retrieved context theories suggest that covert retrievals during a delay interval should specifically predict the initiation of recall. To test t

Auditory categorization is a crucial aspect of everyday communication, but we lack a clear understanding of the computations performed by the brain to define boundaries between groups of natural sounds. While modern machine-learning-based classifiers perform as well as humans in categorizing sounds, they can rely on idiosyncratic acoustic cues that diverge from biologically relevant cues. We hypothesized that, since auditory cortical neurons show robust category selectivity, training a classifier with an auditory cortical front end should more accurately reflect biological categorization.
