海马-隔纤维，标记顺行变性后横断的穹窿海马伞，被发现建立不对称的突触联系上确定（高尔基体浸渍和金色色调）多极神经元的脊在隔区的背外侧核。来自文献的证据表明，这些细胞投射到内侧隔神经元上，内侧隔神经元又投射回海马结构。因此，本研究建立了这个回路中缺失的一环，即，一组海马纤维的靶细胞。
Hippocampo-septal fibers, labeled by anterograde degeneration following transection of the fimbriafornix, were found to establish asymmetric synaptic contacts on spines of identified (Golgi-impregnated and gold-toned) multipolar neurons in the dorsolateral nucleus of the septal region. Evidence from the literature suggests that these cells project onto medial septal neurons, which in turn project back to the hippocampal formation. The present study thus establishes a missing link in this circuitry, viz., one group of target cells of the hippocampal fibers.
