Visual Abstract (IMAGE) Society for Neuroscience Caption Norihiro Sadato and colleagues used a technique called hyperscanning functional magnetic resonance (fMRI) imaging to observe two people as they gazed into their partner's eyes. A video camera and screen in each person's fMRI scanner allowed the researchers to compare brain activity during this social task in real-time or with a 20-second delay.
