New research suggests dancers are as in sync with their minds as they are with their steps, according to scientists at the University of Colorado, who have found that dancing partners can align their brain activity in real time as they move.
The team discovered that when experienced tango dancers move in sync, their brain activity begins to mirror one another in striking ways, offering new insight into how humans connect through complex social behaviors such as dance.
The study, led by graduate student Thiago Roque of the ATLAS Institute, used electroencephalogram (EEG) caps to measure brain activity in pairs of dancers performing the Argentine tango—a style known for its intimacy and improvisational structure, which allows partners to communicate through movement rather than words.
“When we dance, our brains are actually coupling,” said Roque in a statement. “We are synchronizing our brains through our behavior.”
Interbrain Coupling
The researchers recruited five pairs of experienced dancers and equipped them with EEG caps to record brain signals and ankle sensors to track foot movements as they danced in a lab setting. The team then compared the timing of their steps with patterns of brain activity.
The results revealed a clear pattern: when dancers were closely aligned in their movements, their brain waves also became more connected and similar. This phenomenon, known as interbrain coupling or neural synchronization, occurred across multiple types of brain waves, including fast beta waves.
“The coupling was even better than I expected,” he said.
The research team notes that this study is the first to demonstrate neural synchronization during partnered dance, extending earlier findings from studies of musicians performing together.
“When we are performing, we aren’t conscious of this sort of synchronization,” Roque said. “My goal was to bring unconscious things to the conscious level.”
Beyond observing this brain-to-brain connection, the team also experimented with a wearable biofeedback device designed to make synchronization more tangible. The device, worn on the wrist, vibrates when the dancers’ brain activity aligns.
“It almost enhanced that feeling of connection,” Sun said.
“When I started seeing the results, they were perfect. The coupling was even better than I expected, “ adds Roque.
The team believes the findings could have broader applications, including improving coordination in team sports and enhancing how group-based activities and learning are structured by making unconscious alignment visible. In dance, this could translate into a more physically noticeable sense of connection.
Overall, the system could help people better understand how they interact with others in real time.
“In sports, you need to know what your teammates are going to do,” Roque said in a statement. “By using a system like this, they may be able to better learn how to understand each other during training.”
