Penumbria: Advanced 3D cell segmentation for biomedical imaging

Penumbria improves 3D cell segmentation in biomedical imaging by addressing challenges like diverse morphologies and optical aberrations, achieving state-of-the-art accuracy across multiple datasets.

Positional information drives distinct traits in transcriptomically identified neuronal types

The paper identifies neuronal cell types in the zebrafish optic tectum and shows that transcriptionally similar neurons can have distinct functional and morphological traits based on their spatial position.

Visual recognition of social signals by a tecto-thalamic neural circuit

The paper identifies a tecto-thalamic neural circuit that processes visual social signals and drives social attraction in zebrafish.

Neuronal circuitry for stimulus selection in the visual system

This study identifies context-dependent contributions of retinotectal and isthmotectal circuits to visual saliency map computation in larval zebrafish using behavioral and functional recordings.

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.
