digits forward DF and digits backwards DB activate networks of FPN associated with working memory including right dorsolateralprefrontal cortex (DLPRC), bilateral inferior parietal lobue IPL, and ACC (anterior cingulate). DB ALSO activates left DLPFC. ACC monitors effort of performance, activates more with harder tasks. Cerebellum also activates. ACC to cerebellar peduncles support attention and working memory.
VN especially medial occipital play a role in orienting, maintaining and repressing attention. It projects to both visual and auditory sensory processing areas. Both visual and auditory areas are activated with auditorily presented DS.
