This study identifies astrocytic calcium-event sequences in the dorsal hippocampus during learning and memory tasks, showing they encode time-compressed information similar to neuronal time cells.

This study shows that repeated activation of negative memory engrams in mice leads to lasting cellular and behavioral abnormalities, similar to chronic negative thinking in humans.

This study shows that optogenetic reactivation of fear memories in the hippocampus reproduces cellular activity patterns seen during natural memory recall, highlighting neuronal-astrocytic coupling in fear behavior.

This study shows that basolateral amygdala astrocytes are responsive to fear memory acquisition and recall, with distinct calcium dynamics during fear conditioning and extinction.

The paper reactivates hippocampal fear engrams across different contexts and identifies brain-wide network changes associated with distinct defensive behaviors.
