摘要：
This study examines the effect of categorization-task training on parietal (PPC) and prefrontal (PFC) activity and finds a learning-dependent emergence of memory-related delay activity in PPC, whereas PFC shows delay-period selectivity both before and after categorization training. This reveals distinct roles of PFC and PPC in short-term working memory.
