Abstract
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 appropiate. 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.
