Brain imaging studies have been conducted with the reading span task or related tasks. Increased activation during these tasks was found in the PFC and, in several studies, also in the anterior cingulate cortex (ACC). People performing better on the task showed larger increase of activation in these areas, and their activation was correlated more over time, suggesting that their neural activity in these two areas was better coordinated, possibly due to stronger connectivity.

脑成像研究已用于进行阅读广度任务或相关任务，发现在这些任务中PFC的激活增加，在几项研究中还发现前扣带皮层(ACC)的激活增强。任务表现更好的人在这些区域也发生大幅的激活增加，随时间推移其相关性更强，表明表明他们这两个区域的神经活动协调度更高，可能是由于更强连接性。
