Visual Threat Location Impacts Brain‐Wide Visual Adaptation Networks

open access: yesJournal of Comparative Neurology, Volume 534, Issue 7, July 2026.
Mancienne et al. explored the impacts of varying stimulus position on visual adaptation in zebrafish larvae. They found that responses to a looming stimulus in a particular visual position adapt quickly, but that looms elsewhere in the visual field have little impact on adaptation to the reference stimulus.

Creation of an MRI‐Based Three‐Dimensional Common Wombat (Vombatus ursinus) Brain Atlas and Linking Brain Morphometry to Wombat Behaviour

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 4, July 2026.
ABSTRACT Marsupials lack a corpus callosum; in its place Diprodontia have a fasciculus aberrans connecting the hemispheres. However, despite this uniqueness, the realm of marsupial brain anatomy remains largely unexplored, especially through the lens of modern imaging techniques.

HSP101‐encoding NEO‐TETRAPLOID RICE FERTILITY GENE 1 regulates tapetum development through interaction with SAPK2 in polyploid rice

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 7, Page 2316-2330, July 2026.
In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.

Notch receptor expression in the adult zebrafish optic tectum.

open access: yes, 2013
Cross-sections at the indicated level through the mesencephalon; optic tectum area shown in the micrographs is indicated in the cross section schematic in A. Brighfield images show the expression (by ISH) of A, notch1a, B, notch1b and C, notch3 along the

Meis1 specifies positional information in the retina and tectum to organize the zebrafish visual system

open access: yesNeural Development, 2010
Background During visual system development, multiple signalling pathways cooperate to specify axial polarity within the retina and optic tectum. This information is required for the topographic mapping of retinal ganglion cell axons on the tectum. Meis1

A sensory ecology approach to understanding snakebites: Influence of sensory cues on the strike of the lancehead pitviper

open access: yesJournal of Zoology, Volume 329, Issue 3, Page 237-246, July 2026.
Snakes are notable for having a broad range of predators and one of the most diverse repertoires of defensive behaviors. During heightened responses to aversive stimuli, one of the behaviors displayed is the venomous bite, particularly relevant because it triggers snakebite incidents in humans.

Nicotinic potentiation of frog retinotectal transmission in tectum layer F by α3β2, α4β2, α2β4, α6β2, or α7 acetylcholine receptor subtypes

open access: yesMedicina, 2015
Objective: The aim of the study was to explore the effect of semi-specific antagonists and agonists of the nicotinic acetylcholine receptors on the paired-pulse facilitation and nicotinic tonic and phasic potentiation of the frog retinotectal synaptic ...

Sodium nitroprusside prevents the detrimental effects of glucose on the neurovascular unit and behaviour in zebrafish

open access: yesDisease Models & Mechanisms, 2019
Diabetes is associated with dysfunction of the neurovascular unit, although the mechanisms of this are incompletely understood and currently no treatment exists to prevent these negative effects.

SINs and SOMs: Neural microcircuits for size tuning in the zebrafish and mouse visual pathway.

open access: yesFrontiers in Neural Circuits, 2013
In many animals, a fast and reliable circuit for discriminating between predator-sized objects and edible (prey-sized) objects is necessary for survival. How are receptive fields in visual brain areas organized to extract information about size?

Photoevoked response of the optic tectum in larval stage XII and juvenile Rana catesbeiana [PDF]

open access: yes, 1976
The previous cytological and electrophysiological work suggests that the optic tectum matures during metamorphic climax. It was the aim of the present work to attempt to compare pre metamorphic (Stage XII) larval and post metamorphic juvenile, Rana ...
