Mechanisms of Feedback in the Visual System
… We recorded extracellularly within the nucleus isthmi, a nucleus providing direct topographic feedback to the optic tectum, a nucleus that receives the vast majority of retinal output. The optic tectum and nucleus isthmi of the amphibian are homologous structures to the superior colliculus and …

The tectal-isthmic loop of the chicken (Gallus gallus) in a slice preparation : electrophysiology of its elements
… system in the vertebrate midbrain is the tectal-isthmic loop. The optic tectum (superior colliculus in mammals) is a multimodal structure and it is the primary visual processing area in the mesencephalon of non-mammals. The isthmic system (nucleus parabigeminalis in mammals) is a complex of …

The Mechanisms And Roles Of Feedback Loops For Visual Processing
… of the optic tectum: OT) and three nucleus isthmi: Imc, Ipc and SLu. The tectal layer 10 neurons project to ipsilateral Imc, Ipc and SLu in a topographic way. In turn Ipc and SLu send back topographical: local) cholinergic terminals to the OT, whereas Imc sends non-topographical: global) …
