Summary:
- Researchers at the University of California, Irvine, have identified a specific neural circuit in the brain—the ventral hippocampus to the medial prefrontal cortex—that regulates the persistence of fear memories.
- The study reveals that by manipulating this circuit using optogenetics, scientists were able to artificially weaken or strengthen fear responses in mice, offering potential therapeutic targets for treating post-traumatic stress disorder (PTSD) and anxiety-related conditions.
