Scientists uncover insights into neuron function by measuring two key signals simultaneously in living animals

When triggered by odor, C. elegans olfactory neurons undergo rapid changes in membrane potential and intracellular calcium ion levels, leading to fluctuations in the fluorescence intensity of membrane potential sensors and calcium ion sensors. Researchers at Kyushu University measured these changes simultaneously using high-speed capture under a microscope and subsequent image processing, showing that the two signals encode different information…
