Emotional regulation, social understanding, and interpersonal trust can stem from neural attunement.

Healthy human development may depend on what happens between connected brains.

Stronger happy mother-daughter brain coupling was associated with fewer emotional difficulties in daughters.

For decades, psychologists have known that children are influenced by the emotional climate of their homes. What is becoming increasingly clear is that this influence may extend beyond behavior and into the moment-to-moment synchronization of a parent and a child's brains.

Our brains continually align with one another through communication, emotion, attention, and shared experience.

A current line of research on brain coupling suggests that human beings are not isolated minds operating independently. Instead, our brains continually align with one another through communication, emotion, attention, and shared experience (Wang et al., 2026).

More than a decade ago, neuroscientist Hasson et al. (2012) proposed a bold idea: many aspects of human cognition emerge not within a single brain, but between brains. They argued that communication works because neural activity in one person becomes coupled to neural activity in another person through speech, facial expressions, gestures, and social interaction. In their view, successful communication depends on the creation of a shared neural world.

Successful communication depends on the creation of a shared neural world.

Fourteen years ago, their contribution to what we know was largely theoretical. It drew upon studies showing synchronization between speakers and listeners, mothers and infants, romantic........
