How the Brain Reactivates Emotional Experiences
A new study using direct recordings from human brains reveals how the amygdala and hippocampus coordinate to form and retrieve emotional memories. During aversive memory encoding, high-frequency gamma activity in the amygdala shapes hippocampal responses, which are later reactivated in the hippocampus—but not the amygdala—during memory recall. These patterns were uniquely tied to correctly remembered emotional scenes and absent for neutral memories. The findings offer a mechanistic explanation for why emotionally intense experiences are often more vividly remembered and point to new therapeutic avenues for memory-related disorders. ….[READ]
