After injections of HRP into area PG(7a) labelled cells have been found in architectonic areas OA, PE, the cingulate and retrosplenial areas medial to area PG; posteriorly areas MST, OA (V4), V2, V3 and the cortex in the walls and floor of the superior temporal sulcus have also been labelled. Small injections placed in PG have resulted in different parts of these areas being labelled, suggesting that these cortico-cortical connections are well organized and raising the possibility of an ordered representation of the visual field in PG. It is suggested that the vertical meridian is around the boundary and the horizontal meridian passes antero-posteriorly across about the middle of its medio-lateral extent; the central part of the visual field is in the depths of the intraparietal sulcus, and the periphery is on the surface of the inferior parietal lobule and in the anterior wall of the upper part of the superior temporal sulcus. The lower visual field is medial and the upper field is lateral.
将辣根过氧化物酶注射到PG区（7a区）后，在PG区内侧的视区（OA）、PE区、扣带回和压后皮质区发现了标记细胞；在后方，颞上沟壁和底的内侧颞区（MST）、视区（OA，即V4）、V2、V3以及皮质也被标记。将小剂量注射到PG区会导致这些区域的不同部分被标记，这表明这些皮质-皮质连接组织良好，并增加了PG区存在视野有序表征的可能性。有人认为，垂直子午线位于边界附近，水平子午线从前向后穿过其内外侧范围的中部左右；视野的中央部分位于顶内沟深处，周边部分位于顶下小叶表面和颞上沟上部的前壁。下视野在内侧，上视野在外侧。
