The Mere Sight of a Sick Person Can Trigger Our Immune System

The mere sight of a sick person may set off an alarm system in your brain and body, even if they are too far away to infect you.

Brain's Virtual Infection Signals Activate Immune Defense

In a groundbreaking new study published in Nature Neuroscience, researchers have unveiled a remarkable link between the brain’s anticipatory neural mechanisms and the activation of the immune system, even in the absence of real infection. The findings challenge the traditional understanding that immune responses are solely driven by the physical presence of pathogens. Instead, the brain’s predictive processing—its capacity to anticipate virtual …
