Your brain doesn’t work the same on Zoom, scientists say

Scientists have discovered that when you chat to someone on Zoom, your brain does not function the same way. The current study discovered that neural signaling is much lower during video calls than during in-person conversations.
Upon observing a live subject's brain activity during speech, scientists discovered a sophisticated and intricate network of neural activity. But that was far less on Zoom. It implies that communicating with people virtually still lacks something essential. The researchers propose that facial expressions do not have the same effect on brain activity. That comes as a bit of a surprise because, according to existing models, people's faces should be processed by the brain in the same way whether they are in person or on Zoom because they have similar features. However, the results of the new study point to a real difference between the two situations. “In this study we find that the social systems of the human brain are more active during real live in-person encounters than on Zoom,” said Joy Hirsch, a Yale professor who was the lead author on the new study. “Zoom appears to be an impoverished social communication system relative to in-person conditions.”
