Summary: New brain imaging research shows that listening to nostalgic music activates core brain systems involved in memory, self-reflection and reward. Songs tied to personal life events produce stronger neural responses than unfamiliar music, a pattern that helps explain music’s powerful emotional pull and its potential to support people with memory disorders.
Researchers used functional MRI to examine how the brain responds when people hear personally meaningful songs. The study found that music-evoked nostalgia engages the brain’s default mode network (a system linked to autobiographical memory and self-referential thought) as well as reward-related circuits. These coordinated activations offer a biological explanation for why certain songs can vividly retrieve past experiences and lift mood, and suggest a promising nonpharmacological approach to improving quality of life for individuals with Alzheimer’s disease and other memory impairments.
Key Facts:
- Neural Activation: Nostalgic music stimulates both memory-related and reward-related brain regions, producing a distinct neural signature.
- Therapeutic Potential: Tailored music may help support emotional well-being and cognitive function in people with memory loss.
- Personal Connection: Songs tied to meaningful personal experiences evoke stronger brain responses than familiar but non-nostalgic or unfamiliar music.

When a familiar song from your past plays — a prom slow dance, a road-trip anthem, or a tune from a meaningful moment — it does more than trigger a memory. It activates brain networks linked to identity, emotion and reward.
Led by Assal Habibi at the Brain and Creativity Institute (BCI) at USC Dornsife, the new study mapped the neural response to personally significant music and identified a reliable pattern of activation across brain systems involved in autobiographical memory and affective experience. Published in the journal Human Brain Mapping, the findings illuminate how music can serve as a direct, non-drug intervention to help people reconnect with memories and feelings that might otherwise be difficult to access.
“Music is deeply intertwined with our sense of identity and personal history,” said Habibi, associate professor (research) of psychology and neurology. “What we’re seeing is that nostalgic songs don’t just bring back memories — they activate the brain in ways that could support emotional well-being and cognitive function, especially in individuals living with memory impairments.”
Using functional MRI to record brain activity while participants listened to songs selected for their personal significance, the team identified a neural signature for music-evoked nostalgia. That signature includes heightened activity in the default mode network, salience and reward networks, medial temporal lobe structures that support memory, and supplementary motor regions. The coordinated engagement of these systems helps explain why music often produces vivid autobiographical recall and strong emotional responses.
About the study
The research team included Assal Habibi, corresponding and lead author Sarah Hennessy (formerly a USC Dornsife graduate student, now a postdoctoral scholar at the University of Arizona), Jonas Kaplan and Talia Ginsberg of USC Dornsife, and Petr Janata of the University of California, Davis. The project combined neuroscientific imaging with a novel experimental design to compare personally tailored nostalgic music with familiar but non-nostalgic songs and unfamiliar music matched for musical features.
Funding: The study received support from the Grammy Museum Foundation Scientific Research Award, the Brain and Creativity Institute, and the USC Hearing and Communication Neuroscience T32 Fellowship.

Abstract
Music-Evoked Nostalgia Activates Default Mode and Reward Networks Across the Lifespan
Nostalgia, often triggered by music, combines memory and emotion and can temporarily boost autobiographical recall in people experiencing cognitive decline. To explore the neural mechanisms behind music-evoked nostalgia, researchers examined healthy younger and older adults using rigorously controlled, personalized stimuli. They addressed methodological challenges—such as the need for individually tailored songs that remain matched on musical features—by employing a machine-learning approach to create three stimulus categories: (1) personalized nostalgic songs, (2) familiar but non-nostalgic songs, and (3) unfamiliar non-nostalgic songs.
In a sample of 57 participants (29 aged 18–35; 28 aged 60 and older), fMRI analyses revealed four principal findings: (1) Listening to nostalgic music produced greater bilateral activation than control music across the default mode, salience and reward networks, as well as in medial temporal and supplementary motor regions; (2) Psychophysiological interaction models showed enhanced functional connectivity between self-referential regions (such as the posteromedial cortex) and affect-related areas (including the insula) during nostalgic listening; (3) Older adults exhibited stronger BOLD responses in nostalgia-related regions compared with younger adults; (4) In younger adults, neural responses to nostalgic music correlated with trait measures of nostalgia proneness and cognitive ability, whereas in older adults the neural response related more directly to their emotional reactions to the music.
Together, these results define a neural basis for music-evoked nostalgia and support the idea that personalized music interventions could be a practical, nonpharmacological strategy to help retrieve autobiographical memories and enhance emotional well-being across the lifespan.
