Astrocytes, Not Neurons, Hold the Key to Emotional Memory
Summary: New research reveals that astrocytes — not neurons — are responsible for stabilizing emotional memories by re-engaging during recall. After an emotionally intense event, such as fear, specific astrocytes become biologically tagged with adrenoreceptors, making them responsive when the memory is later reactivated. Blocking these astrocytes disrupts memory stability, while forcing them to activate exaggerates fear responses and causes overgeneralization. The findings u
