New vision model analyzes C. elegans neurons for neurotoxicity assessment

Researchers have developed a new self-supervised vision model specifically designed for analyzing neuronal images of Caenorhabditis elegans, a nematode worm used in neurotoxicity studies. This model, named CeNeuMorph, employs a scale-adaptive masked image modeling strategy to effectively learn representations across different resolutions, addressing the limitations of general vision models in capturing sparse signals and multi-scale lesions in neuronal imaging. The model demonstrates superior performance in classification, segmentation, and detection tasks compared to existing models and can predict behavioral deficits based on morphological features. This advancement offers a scalable, computationally tractable alternative to traditional mammalian in vivo models for neurotoxicity assessment and drug discovery, with initial screening identifying benzimidazole as a potential neurotoxicant.
