Binocular integration of prey stimuli in the zebrafish visual system

The paper identifies binocular prey-responsive neurons in zebrafish and shows their role in encoding prey position through visual and motor inputs during hunting.

Toward Crosstalk-free All-optical Interrogation of Neural Circuits

This paper introduces an active pixel power control method to reduce crosstalk in two-photon optogenetics and calcium imaging, improving the accuracy of neural circuit analysis in zebrafish.

Neuropeptide signalling and perineurial barrier generate a persistent stress-induced internal state in Drosophila

This study identifies neuropeptide signalling and perineurial barrier activation as mechanisms underlying persistent stress-induced behavioral changes in Drosophila.

The visuomotor transformations underlying target-directed behavior

The paper identifies sensorimotor neurons in the zebrafish optic tectum and downstream areas that transform visual stimuli into specific behavioral outputs during hunting, freezing, and escape.

Parental thermal conditions affect the brain activity response to alarm cue in larval zebrafish

This study shows that parental exposure to elevated temperature affects larval zebrafish brain activity response to alarm cues, with interactions between parental and offspring thermal conditions influencing response duration.

Warming affects routine swimming activity and novel odour molecular response in larval zebrafish

This study shows that warming reduces routine swimming in larval zebrafish and alters molecular responses to novel odours, with energy trade-offs in gene expression.

What the Zebrafish's Eye Tells the Zebrafish's Brain: Retinal Ganglion Cells for Prey Capture and Colour Vision

The paper characterizes retinal ganglion cells (RGCs) in larval zebrafish, revealing UV-responsive RGCs and complex color opponency, suggesting a dual-achromatic visual strategy for prey capture and color vision.

Deconstructing hunting behavior reveals a tightly coupled stimulus-response loop

The paper analyzes zebrafish hunting behavior using unsupervised methods to identify behavioral modules and their temporal organization in prey capture.
