Module 7: Figure astrocytic synchronization of hippocampal neurons

Synchronization of hippocampal neural activity by spontaneous astrocytic Ca2+ transients.

The arrangement of the astrocyte (cell 1) and the three neurons (cells 2, 3 and 4) are outlined in panel A. Panel B reveals how a spontaneous transient in the astrocyte resulted in a delayed, but synchronous elevation in all three neurons.
