一般智力（g）与工作记忆容量（WMC）高度相关。有人认为，这些中央心理结构应该共享共同的神经系统。本研究采用结构磁共振成像来检验这一假设，以确定区域灰质体积与一般智力和记忆广度相关的大脑区域中的任何重叠。在正常志愿者（N = 48）中，结果（p <0.05，多重比较校正）表明，这些结构的共同解剖框架主要涉及属于Brodmann区（BA）10（右侧上级额回和左侧额中回）的额叶灰质区域，以及较小程度的右侧顶下小叶（BA 40）。这些发现支持了一个离散的顶额网络的核作用。
General intelligence (g) is highly correlated with working-memory capacity (WMC). It has been argued that these central psychological constructs should share common neural systems. The present study examines this hypothesis using structural magnetic resonance imaging to determine any overlap in brain areas where regional grey matter volumes are correlated to measures of general intelligence and to memory span. In normal volunteers (N = 48) the results (p < .05, corrected for multiple comparisons) indicate that a common anatomic framework for these constructs implicates mainly frontal grey matter regions belonging to Brodmann area (BA) 10 (right superior frontal gyrus and left middle frontal gyrus) and, to a lesser degree, the right inferior parietal lobule (BA 40). These findings support the nuclear role of a discrete parieto-frontal network.
