正如Marco Fedele最先描述的那样，肠囊有一个与背束相关的发育良好的神经丛。背束神经丛与促性腺激素释放激素的抗血清呈免疫反应。免疫反应见于位于周围的细胞体，以及贯穿背侧血窦、进入鳃囊并通过内脏神经穿透大脑的突起。神经丛为生殖道提供丰富的神经支配，在性腺中已见突起。心包没有被神经丛的突起支配，直肠的神经支配很差，但神经丛在内脏中的完整范围仍然不确定。虽然这项研究证实了费德勒的许多观察结果，但它并不支持背束神经丛等同于脊椎动物内脏神经系统的观点。
Ciona intestinalis has a well developed nerve plexus associated with the dorsal strand, as first described by Marco Fedele. The dorsal strand plexus is immunoreactive with antisera against gonadotropin-releasing hormone. Immunoreactivity is seen in the cell bodies, which lie peripherally, and in processes which run throughout the dorsal blood sinus, enter the branchial sac and penetrate the brain via the visceral nerve. The plexus provides a rich innervation of the gonoducts, and processes have been seen in the gonads. The pericardium is not innervated by processes from the plexus and the rectum is poorly innervated, but the full extent of the plexus in the viscera remains uncertain. While this study confirms many of Fedele's observations, it does not support the view that the dorsal strand plexus is equivalent to the vertebrate visceral nervous system.
