Live imaging of the molecular clockwork within the circadian pacemaker neurons offers the unique possibility to study complex interactions between the molecular clock and neuronal communication within individual neurons and throughout the entire circadian circuitry. Here we describe how to establish brain explants and dissociated neuron culture from Drosophila larvae, guidelines for time-lapse fluorescence microscopy, and the method of image analysis. This approach enables the long-term monitoring of fluorescence signals of circadian reporters at single-cell resolution and can be also applicable to analyze real-time expression of other fluorescent probes in Drosophila neurons.
