Atypical Cadherin Fat2 is Involved in Axogenesis of Cerebellar Granule Cells in Zebrafish

Development, Growth &Differentiation, Volume 68, Issue 4-5, May‐June 2026.
Granule cells are the most abundant neurons in the vertebrate brain. The atypical cadherin gene fat2 is specifically expressed in cerebellar granule cells. In wild‐type zebrafish larvae, granule cells in the caudolateral cerebellum project their axons straight to Purkinje cells (PCs) and further extend them caudally to innervate crest cells (Crs ...

Retinotectal projections influence optic tectum growth in zebrafish [PDF]

, 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 ...

Protocadherin 19 regulates axon guidance in the developing Xenopus retinotectal pathway

Molecular 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

Diversity, 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 ...

The Impacts of Pregnancy on Cognition and Cell Proliferation in a Live‐Bearing Fish (Poeciliopsis gracilis)

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
We assessed the impact of pregnancy on cognition and cell proliferation in the live‐bearing fish Poeciliopsis gracilis. Pregnant females showed reduced spatial learning but unchanged reversal learning, alongside decreased cell proliferation in the olfactory bulb and ventral telencephalon, indicating pregnancy‐induced cognitive and neural changes in a ...

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

, 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

Nature 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.

“Nothing” Really Matters: What Omission Responses Reveal About the Predictive Brain

European Journal of Neuroscience, Volume 63, Issue 10, May 2026.
Omission paradigms reveal the brain's predictions by removing expected events. We propose these responses arise from the cooperation of two computational styles: Local Regularity Encoding (fast, automatic, local circuits, short temporal windows) and Model‐Based Inference (distributed networks, content‐specific predictions, attention‐dependent, rule ...

Neurogenesis during optic tectum regeneration in Xenopus laevis

, 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.

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

The Anatomical Record, Volume 309, Issue 4, Page 826-852, April 2026.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...
