Browsing Hyper-low Calcium Landscapes inside Brain Cells

Browsing Hyper-low Calcium Landscapes inside Brain Cells - Neuroscientists have advanced an imaging technique to monitor free calcium—a key molecular messenger—inside nerve or glial cells, with unprecedented sensitivity. The method has unveiled heterogeneous, sustained intracellular calcium landscapes that depend on age or past cell activity, thus suggesting a substrate for information storage in the brain.
