Retinotectal projections influence optic tectum growth in zebrafish [PDF]

open access: yes, 2015
In the zebrafish visual system, the retina and optic tectum grow in register throughout life. Both regions add new neurons from proliferation zones at their margins, with newly differentiated retinal ganglion cells projecting to, and making new synapses ...

Targeting the Zebrafish Optic Tectum Using In Vivo Electroporation [PDF]

open access: yes, 2010
INTRODUCTIONIn vivo electroporation is a method for delivery of plasmids and other oligonucleotide reagents that offers precise temporal control. In zebrafish, in vivo electroporation is particularly well-suited to delivering green fluorescent protein ...

Neuron types in the zebrafish optic tectum labeled by an id2b transgene [PDF]

open access: yes, 2020
The larval zebrafish optic tectum has emerged as a prominent model for understanding how neural circuits control visually guided behaviors. Further advances in this area will require tools to monitor and manipulate tectal neurons with cell type ...

Protocadherin 19 regulates axon guidance in the developing Xenopus retinotectal pathway

open access: yesMolecular Brain
Protocadherin 19 (Pcdh19) is a homophilic cell adhesion molecule and is involved in a variety of neuronal functions. Here, we tested whether Pcdh19 has a regulatory role in axon guidance using the developing Xenopus retinotectal system.

Beyond Endocasts: Using Predicted Brain-Structure Volumes of Extinct Birds to Assess Neuroanatomical and Behavioral Inferences

open access: yesDiversity, 2020
The shape of the brain influences skull morphology in birds, and both traits are driven by phylogenetic and functional constraints. Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D ...

A Dynamic Change of Microglial States Occurs During the Transition From Photoreceptor Degeneration to Regeneration in Zebrafish pde6c Mutants

open access: yesGlia, Volume 74, Issue 6, June 2026.
Zebrafish pde6c mutants undergo photoreceptor degeneration from 5 dpf, but rods regenerate from 4 wpf. scRNA‐seq of retinal microglia reveals dynamic change of states between 5 dpf and 4 wpf. Two states emerge specifically during regeneration. ABSTRACT Microglia, brain‐resident immune cells, maintain brain homeostasis.

Characterization of CRF immunoreactive neurons in the anuran optic tectum [PDF]

open access: yes, 2008
In amphibians, it has been determined that CRF has an affect on subcortical visual pathways that regulate prey capturing ability. The pathways targeted by CRF effects on visually guided feeding are unknown, but CRF-ir fibers have been reported in the ...

Visual recovery in goldfish following unilateral optic tectum ablation : Evidence of competition between optic axons for tectal targets [PDF]

open access: yes, 1984
Anatomical studies suggest that regenerating optic axons which invade the ipsilateral lobe of the optic tectum following ablation of the contralateral lobe compete with resident optic axons for synaptic sites on tectal neurons.

Spatially precise visual gain control mediated by a cholinergic circuit in the midbrain attention network

open access: yesNature Communications, 2016
Attention and gaze impact the spatial responsiveness of neurons in the optic tectum. Here the authors elucidate the mechanism by which cholinergic inputs affect receptive field properties of tectal neurons in a spatially precise manner in barn owls.

Cellular and molecular representations: Following the lesson of David Goodsell

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract David Goodsell's images have helped, over the last 30 years, thousands of students all over the world to imagine the cellular world by representing molecules, proteins, complexes, viruses, bacteria, and cellular processes. His contributions to the development of Molecular Graphics (MG) have been invaluable, and his retirement is the last (for ...
