Extracellular recordings reveal absence of magneto sensitive units in the avian optic tectum
(Springer Verlag, 2014)
© 2014, The Author(s).There is a consensus that birds detect the earth’s magnetic field and use some of its features for orientation and homing purposes. Since the late 1960s, when the first solid behavioral evidence of ...
Sonic hedgehog (Shh)/Gli modulates the spatial organization of neuroepithelial cell proliferation in the developing chick optic tectum
(2012)
Background: Sonic hedgehog (Shh)/Gli pathway plays an important regulatory role on the neuroepithelial cells (NEc) proliferation in the dorsal regions of the developing vertebrate Central Nervous System. The aim of this ...
Retinal removal up-regulates cannabinoid CB1 receptors in the chick optic tectum
(WILEY-LISS, 2008)
The endocannabinoid system has been implicated in several neurobiological processes, including neurodegeneration and neuro protection. The aim of this study was to evaluate the effects of unilateral retinal ablation on the ...
Temporal-spatial correlation between angiogenesis and corticogenesis in the developing chick optic tectum
(Public Library of Science, 2015-01)
The developing chick optic tectum is a widely used model of corticogenesis and angiogenesis. Cell behaviors involved in corticogenesis and angiogenesis share several regulatory mechanisms. In this way the 3D organizations ...
Morphology, projection pattern, and neurochemical identity of Cajal's "centrifugal neurons": The cells of origin of the tectoventrogeniculate pathway in pigeon (Columba livia) and chicken (Gallus gallus)
(Wiley-Liss Inc., 2014)
The nucleus geniculatus lateralis pars ventralis (GLv) is a prominent retinal target in all amniotes. In birds, it is in receipt of a dense and topographically organized retinal projection. The GLv is also the target of ...
Novel, continuous visual motion induces c-fos expression in the avian optokinetic nuclei and optic tectum
(2009)
We studied the stimulus characteristics necessary for the expression of c-fos protein in optokinetic system neurons using immunocytochemistry. Using whole-field visual motion as a stimulus, we found substantial c-fos ...
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 ...
A cholinergic gating mechanism controlled by competitive interactions in the optic tectum of the pigeon
(2007)
We describe the operation of a midbrain neural circuit in pigeons that may participate in selecting and attending to one visual stimulus from the myriad displayed in their visual environment. This mechanism is based on a ...
