We determined the cortical regions that project directly to the CA1 field of the monkey hippocampus by injecting the retrograde tracers Fast blue, Diamidino yellow or WGA-HRP into CA1 and examining the distribution of labeled cells. In the temporal lobe, large numbers of retrogradely labeled cells were observed in the perirhinal and parahippocampal cortices. Only an occasional labeled cell, however, was observed in the unimodal visual area TE. Additional projections to CA1 arose in the dorsal bank of the superior temporal sulcus, in the rostral and retrosplenial portions of the cingulate cortex, in the agranular insular cortex, and in the caudal orbitofrontal cortex.
我们通过向猴海马体的CA1区注射逆行示踪剂快蓝、双脒基黄或WGA-HRP，并检查标记细胞的分布，来确定直接投射到猴海马体CA1区的皮质区域。在颞叶中，在嗅周皮质和海马旁皮质中观察到大量逆行标记细胞。然而，在单峰视觉区TE中仅偶尔观察到一个标记细胞。向CA1区的其他投射起源于颞上沟的北岸、扣带皮质的嘴侧和压后部分、无颗粒岛叶皮质以及尾侧眶额皮质。
