In this study, specimens of both sexes of a Western Australian wallaby (Steonix brachyurus) had surgical or electrolytic lesions made in the habenular complex unilaterally. Thirty-five-micron sections, cut coronally and parasagittally, were stained by the Nauta-Gygax ('54) or the Fink-Heimer ('67) technique to demonstrate degenerating fibers. Degeneration was seen in the habenular commissure and bilaterally in the habenula and fasciculus retroflexus, but was most extensive ipsilaterally. Habenular fibers destined for the tegmentum and central gray passed caudally into the midbrain in a continuous fan-like array which extended from the central gray dorsally to the interpeduncular nucleus ventrally. In their posterior course some fibers crossed the midline with the decussating cerebellar fibers. The majority of fibers, with those in the fasciculus retroflexus which passed ventral to the decussation of the superior cerebellar peduncle, turned dorsally. They passed mostly just lateral to the midline nuclei and into the central gray where degeneration was seen throughout the entire extent. Terminal degeneration was seen in the interpeduncular nucleus primarily in the dorsal and posterior parts, in the ventral tegmental nucleus and throughout the central gray, but was more densely clustered in the region of the dorsal tegmental nucleus.
在本研究中，对一只西澳沙袋鼠（短尾矮袋鼠）的雌雄标本单侧缰核复合体进行手术或电解损伤。将35微米厚的冠状和矢状旁切片，用Nauta-Gygax（1954年）或Fink-Heimer（1967年）技术染色以显示退变纤维。在缰连合以及双侧缰核和后屈束中均可见退变，但同侧最为广泛。发往被盖和中央灰质的缰核纤维尾侧进入中脑，呈连续扇形排列，从中央灰质背侧延伸至脚间核腹侧。在其向后走行过程中一些纤维与交叉的小脑纤维一起交叉中线。大多数纤维，与后屈束中位于小脑上脚交叉腹侧的纤维一起，转向背侧。它们大多刚好在中线核外侧通过并进入中央灰质，在整个范围内均可见退变。终末退变主要见于脚间核的背侧和后部、腹侧被盖核以及整个中央灰质，但在背侧被盖核区域更为密集。
