Astrozyten, nicht Neuronen, sind der Schlüssel zum emotionalen Gedächtnis: Die Entdeckung definiert neu, wie das Gehirn emotionale Erfahrungen speichert und könnte zu sanfteren Therapien für PTBS führen.

Astrocytes, the brain’s often-overlooked support cells, have been found to play a central role in stabilizing emotionally charged memories.

After a powerful emotional event, these cells are biologically tagged with adrenoreceptors that prime them to reactivate when the memory resurfaces.

When researchers blocked astrocyte activity, memories became unstable; when they forced activation, mild memories were recalled as deeply distressing.
