… astrocytes labeled blue also show green staining for calcium and red staining for ChromeQ a new tool for … the team will target different genes related to calcium biochemistry. One tool will give them temporal … control over receptors that the cells use to regulate calcium levels around neurons, for instance to intentionally …
… new study in mice shows. motor cortex astrocytes astrocyte calcium imaging multiphoton microscopy … the motor cortex,” Delepine said. Above: Imaging based on calcium levels in astrocytes demonstrates the effect of the … In other mice they hyperactivated the astrocytes’ calcium signals, which affected how they function. In both …
… example of data under analysis in the Littleton lab: "Cac" calcium channels (left) allow an influx of calcium to trigger neurotransmitter release, which is observed by calcium fluorescence (center). The overall likelihood of each …
… moment.” The researchers designed their tool to respond to calcium, because neurons experience an flux of calcium ions every time they fire an electrical impulse. However, the neurons are only labeled if this calcium flux occurs while the cell is also exposed to a beam …
… 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 …
… 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 … have their spiking code, we think there is an astrocyte calcium code that reflects and works in partnership with …
