From water to land: Evolution of photoreceptor circuits for vision in air

PLoS Biology, Год журнала: 2024, Номер 22(1), С. e3002422 - e3002422

When vertebrates first conquered the land, they encountered a visual world that was radically distinct from of their aquatic ancestors. Fish exploit strong wavelength-dependent interactions light with water by differentially feeding signals up to 5 spectral photoreceptor types into behavioural programmes. However, above same rules do not apply, and this called for an update circuit strategies. Early tetrapods soon evolved double cone, still poorly understood pair new photoreceptors brought “ancestral terrestrial” complement 7. Subsequent nonmammalian lineages adapted highly parallelised retinal input strategy diverse ecologies. By contrast, mammals shed most ancestral converged on is exceptionally general. In eutherian including in humans, parallelisation emerges gradually as signal traverses layers retina brain.

The Visual Systems of Zebrafish

Annual Review of Neuroscience, Год журнала: 2024, Номер 47(1), С. 255 - 276

Опубликована: Апрель 25, 2024

The zebrafish visual system has become a paradigmatic preparation for behavioral and systems neuroscience. Around 40 types of retinal ganglion cells (RGCs) serve as matched filters stimulus features, including light, optic flow, prey, objects on collision course. RGCs distribute their signals via axon collaterals to 12 retinorecipient areas in forebrain midbrain. major visuomotor hub, the tectum, harbors nine RGC input layers that combine information multiple features. retinotopic map tectum is locally adapted scene statistics subfield–specific demands. Tectal projections premotor centers are topographically organized according commands. known connectivity more than 20 processing streams allows us dissect cellular basis elementary perceptual cognitive functions. Visually evoked responses, such prey capture or loom avoidance, controlled by dedicated multistation pathways that—at least larva—resemble labeled lines. This architecture serves neuronal code's purpose driving adaptive behavior.

The visuomotor transformations underlying target-directed behavior

Proceedings of the National Academy of Sciences, Год журнала: 2025, Номер 122(13)

Опубликована: Март 24, 2025

The visual system can process diverse stimuli and make the decision to execute appropriate behaviors, but it remains unclear where how this transformation takes place. Innate visually evoked behaviors such as hunting, freezing, escape are thought be deeply conserved, have been described in a range of species from insects humans. We found that zebrafish larvae would respond predator-like with immobility bradycardia, both hallmarks head-fixed behavioral paradigm. then imaged while responded different systematically identified driven neurons behaviorally correlated sensorimotor neurons. Our analyses indicate within optic tectum, broadly tuned sensory functionally which specifically during one behavior, indicating contains suitable information for transformation. also four other areas downstream these specific segregation pathways continues areas. While our findings shed light on may integrate inputs, further investigation will required determine regions interact behave is made.

Diverse prey capture strategies in teleost larvae

Опубликована: Фев. 10, 2025

Animal behavior is adapted to the sensory environment in which it evolved, while also being constrained by physical limits, evolutionary history, and developmental trajectories. The hunting of larval zebrafish ( Danio rerio ), a cyprinid native streams Eastern India, has been well characterized. However, unknown if complement sequence movements employed during prey capture universal across freshwater teleosts. Here, we explore syntax fish belonging clade Percomorpha , whose last common ancestor with cyprinids lived ∼240 million years ago. We compared four cichlid species from Lake Tanganyika endemic deep benthic parts lake Lepidiolamprologus attenuatus Lamprologus ocellatus Neolamprologus multifasciatus ) or inhabiting rivers Astatotilapia burtoni that medaka Oryzias latipes found rice paddies East Asia.

Notably, repertoire cichlids broader than zebrafish, but shares basic features, such as convergence, positioning centrally binocular visual field, discrete bouts, including two kinds strikes. In contrast, continuously, track monocularly without position laterally before capturing them side swing. This configuration kinematic motifs suggests may judge distance predominantly motion parallax, mainly use cues. Together, our study documents diversification locomotor oculomotor adaptations among teleost larvae.

Protocol for using UV stimuli to evoke prey capture strikes in head-fixed zebrafish larvae

STAR Protocols, Год журнала: 2023, Номер 5(1), С. 102780 - 102780

Опубликована: Дек. 19, 2023

Hunting in larval zebrafish begins with eye convergence and orienting turns, proceeds to approach swims, ends the strike, where larvae consume prey. Here, we describe a protocol present UV stimuli zebrafish, which greatly increases occurrence of hunting initiation strikes. We also how record analyze strike behavior head-fixed larvae. Our goals are increase robustness prey capture allow other labs implement behavioral assay. For complete details on use execution this protocol, please refer Khan et al. (2023).1
