The trial-to-trial correlation of discharge rates between pairs of neurons (noise correlation) was investigated in the prefrontal cortex, before and after training in a working memory task. Noise correlation differed across neurons depending on their responsiveness and selectivity for stimuli and decreased after learning to perform the task. The results demonstrate that learning alters the correlation structure of neuronal firing in the prefrontal cortex.
