In this paper, we present a brief anatomical description of the torus longitudinalis and the valvula cerebelli in a percomorph fish, the gilthead seabream (Sparus aurata) based on the analysis of serial brain sections stained by paraldehyde fuchsin, Groat's hematoxylin-picroindigocarmin and cresyl violet. The existence of a small undescribed fiber tract directly bridging the ventral torus longitudinalis and the granular layer of the rostral valvula cerebelli is also reported. This small fiber tract was observed in its integrity on a few transverse sections providing that the angle of sectioning was appropriate. The existence of the anatomical link between the TL and the VC described in this paper might sustain the role of the TL as part of an ascending cerebello-tectal circuit, at least in gilthead seabream. However, these fibers might also represent fibers of passage originating from other brain structures.
在本文中，我们基于对经副品红、格罗特苏木精 - 苦味酸靛胭脂和甲酚紫染色的连续脑切片的分析，对鲈形目鱼类金头鲷（Sparus aurata）的纵走隆起和小脑瓣进行了简要的解剖学描述。此外，还报道了一条未被描述过的小纤维束的存在，该纤维束直接连接腹侧纵走隆起和吻侧小脑瓣的颗粒层。只要切片角度合适，在少数横切面上就能完整地观察到这条小纤维束。本文所描述的纵走隆起（TL）和小脑瓣（VC）之间解剖学联系的存在，可能支持纵走隆起作为小脑 - 顶盖上升回路一部分的作用，至少在金头鲷中是这样。然而，这些纤维也可能代表源自其他脑结构的过路纤维。
