… astrocytes do signal their activity with increases of calcium. A decade ago in Science , Sur and colleagues used … formation of neural connections called synapses, how the calcium activity arises, and what difference that activity … is first developing. Using sophisticated and precise imaging tools, Sur’s team will monitor astrocyte and neuron …
… and flexibility of its nervous system C. elegans behavior calciumimaging … neuron in its head (cells are engineered to flash when calcium ions build up). Reliably distinguishing and tracking …
… signals to chemical transmitters requires presynaptic calcium channels that form pores in the cell membrane that … the volume, or change the tune completely. By altering calcium channel function, which can be done using a host of …
… manipulation. Finally, Flavell’s team has developed imaging technologies that enable them to track and map neural … their ability to track all neuron activity (based on their calcium fluctuations) and all behaviors to watch how the … neuron was impacted by serotonin. “We performed brain-wide calciumimaging in freely-moving animals with knowledge of …
… the astrocytes’ ability to signal neurons with calcium. This not only undermined the smoothness of the … on astrocytes. It triggers a sustained increase in their calcium levels. That promotes them to release chemicals that …
… To keep constant track of neural activity, as indicated by calcium-triggered flashes of light, the Flavell lab invented … tracking the worms as they move around, thereby constantly imaging the activity of neurons across the worm’s brain, as indicated by calcium-triggered flashes of light. Ji used the scope to …
