摘要：在Salamandra Salamandra的视神经顶盖单侧离子电泳应用HRP后，在两侧的前顶盖、峡被、网状结构、内侧部和前庭大细胞核中发现逆行充满HRP的细胞。八头外侧肌区只伸到顶盖的尾部。在颈脊髓的背灰色柱、背被、背丘脑内侧部、背丘脑、前部（到顶盖吻侧的三分之一）、丘脑腹侧（在其整个吻尾区）和视前下丘脑复合体上都发现了同侧突起。逆行填充细胞见于对侧顶盖的较深层。有两个远端脑核通过外侧前脑同侧地投射到顶盖：外侧白球的腹侧部分和后纹状核-杏仁核复合体。
SummaryFollowing unilateral iontophoretic application of HRP into the optic tectum of Salamandra salamandra, retrogradely HRP-filled cells were found bilaterally in the pretectum, tegmentum isthmi, the reticular formation, pars medialis, and in the nucleus vestibularis magnocellularis. The area octavo-lateralis projects only to the caudal part of the tectum. Ipsilateral projections were noted from the dorsal gray columns of the cervical spinal cord, the dorsal tegmentum, the thalamus dorsalis pars medialis, thalamus dorsalis, pars anterior (to the rostral one-third of the tectum), the thalamus ventralis (in its entire rostro-caudal extent), and the preoptico-hypothalamic complex. Retrogradely filled cells were identified in deeper layers of the contralateral tectum. There are two telencephalic nuclei projecting ipsilaterally to the tectum via the lateral forebrain: the ventral part of the lateral pallium, and the posterior strio-amygdalar complex.
