Detecting Physiological Responses from Sensory Neurons in <em>Drosophila</em>

Source: Shankar, S., et al. Measuring Physiological Responses of Drosophila Sensory Neurons to Lipid Pheromones Using Live Calcium Imaging. J. Vis. Exp. (2016). This video demonstrates a method for detecting sensory neuron responses in Drosophila using ligand binding and fluorescence imaging. Ligands bind to neuron receptors, causing calcium influx. The calcium binds to indicator complexes, leading to fluorescence emission, which confirms the neuronal response to the ligand.
