A new study adds evidence to the idea of the behavioral immune system, showing that participants respond to infectious avatars by turning on threat-detecting brain areas and priming an immune response to a potential infection.

Human brain may anticipate looming contagion
Seeing a visibly ill avatar in virtual reality activates a neuroimmune pathway in brain areas related to peripersonal space and prompts an immune response, a small new study suggests.

New neurons aren’t just for childhood. 🧠

A breakthrough study shows the adult hippocampus continues to produce neural progenitor cells, and even divides new neurons, well into our 70s. Hope for lifelong learning and brain repair.
