Researchers have recently found that the level of neural activity is markedly diminished during online interactions as opposed to in-person conversations.
Joy Hirsch, a neuroscientist at Yale University, employed sophisticated imaging techniques to scrutinize real-time brain activity between two persons involved in a conversation. She noted a complex pattern of neural engagement in regions of the brain responsible for social behavior. However, upon replicating the experiments using Zoom, a widely-used video conferencing software, she documented a considerably different neurobiological landscape.
The scientific team observed that neural signaling was substantially muted in online interactions in comparison to the activity seen during in-person conversations.
The study has been recently published in the journal Imaging Neuroscience.

A Comparative Analysis: Zoom Versus In-Person Conversations
“In our research, we observe that the human brain’s social networks are more activated during actual, live, face-to-face interactions as opposed to those on Zoom,” stated Hirsch, who is the Elizabeth Mears and House Jameson Professor of Psychiatry, and also holds professorships in comparative medicine and neuroscience. She is the senior author of the study. “Zoom, in comparison to direct interactions, appears to offer a less enriched social communication system.”
Social engagements form the bedrock of all human societies. The human brain is highly specialized to interpret dynamic facial cues, a primary means of social communication, during live, in-person interactions. While much of the prior research utilizing imaging technologies has focused on individual brain activity, Hirsch’s lab has developed a unique set of neuroimaging tools that facilitate real-time examinations of interactions between two people in natural settings.
Findings and Their Significance
In this novel study, the research team analyzed neural responses in people participating in real-time, two-person dialogues as well as in those engaging in two-person discussions over Zoom, a video conferencing platform now utilized by millions daily in the United States.
They discovered a significant diminishment in the strength of neural signaling during Zoom interactions compared to in-person conversations. Heightened activity in direct conversations correlated with extended gaze time and enlarged pupil diameters, indicating increased arousal in the participants’ brains. Enhanced EEG activity during direct encounters was indicative of better facial recognition capabilities, the researchers noted.
Moreover, they detected greater synchronicity in neural activity between individuals participating in face-to-face conversations, which may imply a heightened exchange of social cues between the parties involved.
“Fundamentally, the organic and dynamic social interactions typically occurring during face-to-face interactions seem to be either less prominent or entirely missing in Zoom encounters,” said Hirsch. “This effect is highly robust.”
The results underline the critical importance of live, face-to-face interactions for our innate social tendencies, Hirsch explained.
“Current technology’s digital renditions of faces do not appear to access the same specialized neural pathways in the brain that real-world faces do,” she concluded.

Frequently Asked Questions (FAQs) about Neural Activity in Face-to-Face vs. Zoom Conversations
What is the main focus of the recent study led by Joy Hirsch?
The study led by Yale neuroscientist Joy Hirsch aims to investigate the differences in neural activity between in-person conversations and online interactions conducted over Zoom. Sophisticated imaging tools were employed to observe and analyze real-time brain activity during these two types of interactions.
What methods were used to monitor neural activity?
Advanced imaging techniques were used to monitor real-time neural activity in participants engaged in face-to-face conversations as well as those conversing via Zoom. Hirsch’s lab developed a unique suite of neuroimaging technologies that allows real-time study of interactions between two individuals in natural settings.
What significant differences were observed in neural activity between in-person and Zoom interactions?
The researchers found that neural signaling was substantially reduced during Zoom conversations compared to face-to-face dialogues. In addition, increased activity during in-person conversations was associated with extended gaze time and enlarged pupil diameters, suggesting heightened arousal in the participants’ brains.
Where were the findings of this study published?
The findings were published in the journal Imaging Neuroscience.
What are the implications of this study?
The study indicates that the social systems of the human brain are more activated during real, live, face-to-face interactions as compared to online conversations on Zoom. This suggests that in-person conversations have a more pronounced impact on our social behaviors and neural activity, emphasizing the neurological importance of direct human interactions.
Who are the co-authors of the study?
The co-authors, all affiliated with Yale University, include Nan Zhao, Xian Zhang, J. Adam Noah, and Mark Tiede.
How does this study contribute to our understanding of social interactions?
The study sheds light on the neurological underpinnings of social interactions, highlighting the importance of face-to-face conversations for more enriched and reciprocal social exchanges. The findings underline the crucial role that direct interactions play in engaging the social neural networks of the brain.
Does the study conclude that online interactions are inherently inferior?
The study suggests that Zoom interactions appear to offer a “less enriched social communication system” compared to in-person interactions. However, it does not necessarily deem online interactions as inherently inferior; it points out that current technology’s digital representations of faces do not have the same specialized access to social neural pathways as real-world faces do.

Interesting study for sure. But what are the implications for the future of work? Companies are pushing remote work like crazy and this could be a big deal!
Wow, this is really eye-opening! Never thought that Zoom and in-person chats would be so different, neurologically speaking. Makes u wonder what we’re missing out in virtual meetups, huh?
Great read! had no idea our brains were so tuned to face-to-face interactions. kinda makes you think twice about the digital age we’re in.
So that’s why Zoom meetings always felt a bit off to me. Science proves it, I guess. it’s not just a feeling, it’s neurological.
What’s next? Studies showing that virtual hugs don’t feel the same? Lol, but seriously, this is important research. Props to Hirsch and team.
