Two distinct populations of tectal neurons have unique connections within the retinotectorotundal pathway of the pigeon (Columba livia)
(1997)
The tectofugal pathway is a massive ascending polysynaptic pathway from the tectum to the thalamus and then to the telencephalon. In birds, the initial component of this pathway is known as the tectorotundal pathway; in ...
The nucleus pretectalis principalis: A pretectal structure hidden in the mammalian thalamus
(Wiley-Liss Inc., 2019)
A defining feature of the amniote tecto‐fugal visual pathway is a massive bilateral projection to the thalamus originating from a distinct neuronal population, tectal ganglion cells (TGCs), of the optic tectum/superior ...
Spatial organization of the pigeon tectorotundal pathway: An interdigitating topographic arrangement
(2003)
The retinotectofugal system is the main visual pathway projecting upon the telencephalon in birds and many other nonmammalian vertebrates. The ascending tectal projection arises exclusively from cells located in layer 13 ...
Conservation and change in the tectofugal visual system of mammals: A comparative studyConservación y cambio en la vía visual tectofugal de mamíferos: Un estudio comparado
(2020)
The tectofugal pathway (TFP; retina-optic tectum-thalamus-visual pallium) is the main visual route to the telencephalon in amniotes. In mammals and birds, the tecto-thalamic portion of this pathway exhibits a diffuse and ...
GABAergic inputs to the nucleus rotundus (pulvinar inferior) of the pigeon (Columba livia)
(1996)
The avian nucleus rotundus, a nucleus that appears to be homologous to the inferior1 caudal pulvinar of mammals, is the major target of an ascending retino-tecto-thalamic pathway.
Further clarification of the inputs to ...
Existe un mecanismo de magnetorecepción fotodependiente en el tectum óptico de las aves
(Universidad de Chile, 2011)
Las aves tienen una bien desarrollada sensibilidad magnética pero la electrofisiologla
básica de esta sensibilidad es aun debatida. En los últimos años se ha presentado una interesante hipótesis que relaciona la ...
Axon terminals from the nucleus isthmi pars parvocellularis control the ascending retinotectofugal output through direct synaptic contact with tectal ganglion cell dendrites
(Wiley & Sons, 2016)
The optic tectum in birds and its homologue the superior colliculus in mammals both send major bilateral, nontopographic projections to the nucleus rotundus and caudal pulvinar, respectively. These projections originate ...
