Cell proliferation and apoptosis in optic nerve and brain integration centers of adult trout Oncorhynchus mykiss after optic nerve injury

open access: yesNeural Regeneration Research, 2016
Fishes have remarkable ability to effectively rebuild the structure of nerve cells and nerve fibers after central nervous system injury. However, the underlying mechanism is poorly understood.

Target selection by surgically misdirected optic fibers in the tectum of goldfish [PDF]

open access: yes, 1984
This study tested the capacity of regenerating optic fibers to read tectal markers and thereby grow to their appropriate tectal loci when initial position, optic pathway, and interfiber interactions are eliminated as useful cues.

HISTOLOGICAL STUDY ON OPTIC TECTUM IN IRAQI WATER SNAKE TESSELATA TESSELATA

open access: yesمجلة بغداد للعلوم
The   ceiling  of the  midbrain  has  a couple  of  optic  lobes  which  are  prominent  and  used  as  an  optic   center  that  reflex   what  it  receives  from   eye  retina   fibers.

Effect of retinal ablation on the expression of calbindin D28k and GABA in the chick optic tectum

open access: yesEuropean Journal of Histochemistry, 2009
The effect of retinal ablation on qualitative and quantitative changes of calbindin D28k and GABA expression in the contralateral optic tectum was studied in young chicks.

Cerebellar output in zebrafish: an analysis of spatial patterns and topography in eurydendroid cell projections

open access: yesFrontiers in Neural Circuits, 2013
The cerebellum is a brain region responsible for motor coordination and for refining motor programs. While a great deal is known about the structure and connectivity of the mammalian cerebellum, fundamental questions regarding its function in behaviour ...

Neurogenesis of retinal ganglion cells is not essential to visual functional recovery after optic nerve injury in adult zebrafish. [PDF]

open access: yesPLoS ONE, 2013
Zebrafish central nervous system (CNS) possesses a strong neural regeneration ability to restore visual function completely after optic nerve injury (ONI).

The Emergence of the Spatial Structure of Tectal Spontaneous Activity Is Independent of Visual Inputs

open access: yesCell Reports, 2017
Summary: The brain is spontaneously active, even in the absence of sensory stimulation. The functionally mature zebrafish optic tectum shows spontaneous activity patterns reflecting a functional connectivity adapted for the circuit’s functional role and ...

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Neurogenesis during optic tectum regeneration in Xenopus laevis [PDF]

open access: yes, 2010
The regenerative neurogenesis of the optic tectum of larval Xenopus laevis has been studied analyzing the proliferative and morphogenetic phases of the regeneration process after removal of one optic lobe.

Visual-Cerebellar Pathways and Their Roles in the Control of Avian Flight

open access: yesFrontiers in Neuroscience, 2018
In this paper, we review the connections and physiology of visual pathways to the cerebellum in birds and consider their role in flight. We emphasize that there are two visual pathways to the cerebellum.
