Новый анализ для холодной ноцицепции в Drosophila личинки

Overview

This study presents a novel assay for investigating cold nociception in Drosophila larvae using a custom-built Peltier probe. The method enables precise application of noxious cold stimuli and quantification of cold-specific behaviors, facilitating further exploration of cold nociception at cellular and molecular levels.
