Fluorescently Labeled Adult C. elegans Swims through a Salt Concentration Gradient (VIDEO)
Caption
Researchers at the University of Tokyo studied worms to understand the neuroplasticity of learning. Three views of the same recording show a worm starting in an area of higher salt concentration, moving towards a lower salt concentration, stopping, and then changing directions to go back towards the higher-salt area. The dark circles are pillars in the container that act like speed bumps, slowing down the worm so the microscope can track its movements. Note how the GcaMP6s signal (middle) becomes brighter when the worm reverses direction. Left: C. elegans viewed under normal white light with a square drawn around the neurons examined in the research. Middle: Fluorescent light view of genetically encoded GCaMP6s, an indicator that a neuron is sending a signal to another neuron. Right: Fluorescent light view of mCherry, a fluorescent tag added to the same neuron as GcaMP6s.
