A genetic labeling system to study dendritic spine development in zebrafish models of neurodevelopmental disorders

open access: yesDisease Models & Mechanisms, 2022
Dendritic spines are the principal site of excitatory synapse formation in the human brain. Several neurodevelopmental disorders cause spines to develop abnormally, resulting in altered spine number and morphology.

Enhanced spontaneous polarization in directional interlayer sliding γ‐InSe for self‐powered, all‐day visual adaptation and motion perception

open access: yesInfoMat, EarlyView.
This study develops a retinal‐inspired optoelectronic sensor based on two‐dimensional γ‐InSe, wherein engineered interlayer sliding enhanced spontaneous polarization. The system utilizes the photo‐pyroelectric effect to simulate the snake's all‐day visual function.

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...

Mapping of the receptive fields in the optic tectum of chicken (Gallus gallus) using sparse noise. [PDF]

open access: yesPLoS ONE, 2013
The optic tectum plays a key role in visual processing in birds. While the input from the retina is topographic in the superficial layers, the deep layers project to the thalamic nucleus rotundus in a functional topographical manner.

Fish welfare in a changing world: New developments and current challenges

open access: yesJournal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Matrix metalloproteinase 14 in the zebrafish: an eye on retinal and retinotectal development. [PDF]

open access: yesPLoS ONE, 2013
Matrix metalloproteinases (MMPs) are members of the metzincin superfamily of proteinases that cleave structural elements of the extracellular matrix and many molecules involved in signal transduction.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Chick PTPσ regulates the targeting of retinal axons within the optic tectum [PDF]

open access: yes, 2002
Chick PTP (cPTP), also known as CRYP, is a receptor-like protein tyrosine phosphatase found on axons and growth cones. Putative ligands for cPTP are distributed within basement membranes and on glial end feet of the retina, optic nerve, and optic tectum,

A Moving Target Detection Model Inspired by Spatio-Temporal Information Accumulation of Avian Tectal Neurons

open access: yesMathematics, 2023
Moving target detection in cluttered backgrounds is always considered a challenging problem for artificial visual systems, but it is an innate instinct of many animal species, especially the avian.
