Anterogradely labeled terminals were found densely in field CA1, but not in any other field, of the hippocampal formation following injections of horseradish peroxidase into the ventral TE area of the inferotemporal cortex, whereas no label was seen in any field of the hippocampal formation following injections into the dorsal TE area. The labeled terminals were distributed mainly in a medial part of the stratum moleculare of field CA1 throughout its rostrocaudal extent. The present finding provides the first demonstration of direct projections from the inferotemporal cortex to the hippocampal formation.
将辣根过氧化物酶注入颞下皮质的腹侧颞叶区域后,在海马结构的CA1区发现了大量顺行标记的终末,但在其他区域未发现;而将辣根过氧化物酶注入背侧颞叶区域后,在海马结构的任何区域均未发现标记。标记的终末主要分布在CA1区分子层的内侧部分,贯穿其前后范围。本研究结果首次证明了颞下皮质到海马结构的直接投射。
