Researchers discovered that anxious individuals utilize a less optimal region of the forebrain when navigating socially challenging situations compared to their non-anxious counterparts. This was determined through brain scans that mapped regions active during simulated social scenarios.

Fluoxetine (Prozac), a common antidepressant, was found to enhance the erasure of learned fear responses and facilitate spatial pattern learning in mice. The study also found the TrkB receptor in PV+ interneurons plays a crucial role in these effects, which may offer new possibilities for the development of psychiatric treatments targeting brain plasticity.
