The ventromedial prefrontal cortex (vmPFC) is associated with processing emotions and the personal significance of memories. It plays a crucial role in biased positive recall, meaning that nostalgic memories are often remembered as more positive and emotionally intense than they may have actually been. The amygdala, known for its involvement in processing emotions and emotional memories, also shows increased activation during nostalgia. This can contribute to the heightened emotional experience associated with nostalgic feelings.
