How Dance Shapes the Brain

FEATURED RESEARCH

The First AI-Driven Model to Predict Brain Activity from Dance

If you’ve ever been caught off guard by someone breaking into choreography in a public place, you know the feeling. Your mind lights up before you even process what you’re looking at.

A new study from the University of Tokyo finally shows why. Using fMRI, a type of brain scan that measures small changes in blood flow to show which regions are active, and an AI-assisted brain-activity simulator, researchers mapped how we process dance at a level of detail no previous study has accomplished.

A new way to study movement: Earlier research often simplified dance into isolated poses or silent clips. This study embraced the complexity instead.

The team relied on the AIST Dance Video Database, a massive collection of more than 13,000 recordings across 10 street-dance genres, along with an AI model capable of generating choreography from music. That allowed them to capture how real-world performances activate the brain.

They recruited 14 participants with mixed dance backgrounds and had them watch 1,163 clips while undergoing fMRI scans.

Because the model extracted cross-modal features (how music and movement combine), it revealed brain responses that motion-only or sound-only features missed.

What the scans showed: Cross-modal features best predicted activity in higher-order association areas, the regions that integrate vision, sound, planning, and meaning.

Street dance produced especially strong responses. And “expert dancers” changed the picture entirely. Experts didn’t converge toward a single pattern. Their responses actually became more diverse, while nonexperts clustered more tightly.

Experience broadened how the brain interpreted movement.

To explore how impressions map onto the brain, the team also created rating scales with input from expert dancers. Running those impressions through the simulator showed distributed neural patterns for emotion and aesthetics rather than one simple dimension.

Why it matters: This work goes beyond dance. It shows how AI and rich real-world datasets can help decode how the brain processes complex art forms. The team even hopes the simulator could one day support new choreography!

And honestly, knowing our brains all “dance” differently makes watching movement feel even more human.

What Caught My Eye

PRODUCT PIPELINE

The FDA Just Approved a Smart Shirt That Can Monitor Your Heart and Lungs in Real Time

We haven’t done a product feature in a while, and this one (out of Canada!) I had to feature.

The FDA just cleared a new smart shirt from Hexoskin that can continuously track heart and respiratory signals, and it comes with long-term monitoring in mind rather than casual wellness.

The shirt collects ECG, heart rate, respiratory rate and activity data while people go about their daily lives. Research teams can now use it in U.S. clinical trials, which matters because long-duration cardiopulmonary data has always been the missing piece for decentralized studies.

The company pairs its hardware with an AI system that looks for digital biomarkers that typically never show up in short clinic visits.

Hexoskin also has an AI model for cough detection trained to work in noisy environments without capturing speech. The privacy angle makes this more practical for real patients rather than idealized lab settings.

I previously wrote about this last year, where another one of their products is designed for use in space for real-time monitoring of astronaut health. Incredible to see their progress since then!

Trivia Answer: C) Tutting

Tutting is a street dance style that uses sharp, angular movements, mainly with the arms and hands, to create geometric shapes. The style is inspired by poses seen in ancient Egyptian art, and its name references King Tutankhamun. It emerged from the popping scene and is often featured in hip-hop and animation dance.
