简介：
Overview
This article discusses a quantitative food-intake assay using dyed food to evaluate feeding motivation in adult Drosophila melanogaster. The method allows for high-throughput analysis and can be combined with thermogenetic and optogenetic screens to explore the neural circuits involved in appetite regulation.
