Moreover, functional magnetic resonance imaging (fMRI) studies have shown that brain regions related to self-representation, such as the medial prefrontal cortex and precuneus, are engaged during nostalgia. This suggests that nostalgia has a self-reflective aspect, allowing individuals to maintain a sense of continuity and connectedness with their past selves. Overall, the brain activation patterns associated with nostalgia suggest that it involves a complex interplay between memory, emotion, and self-processing regions, leading to the evocation of vivid, positive, and emotionally charged recollections of the past.
