These results could prompt more research exploring the therapeutic benefits of psilocybin and how it could foster adaptive behavior. In addition, future work could examine the neural mechanisms ...

A new study shows how a dopamine circuit between two brain regions enables mice to extinguish fear after a peril has passed. Dangers come but dangers also go and when they do, the brain has an ...

Researchers at Tulane University have identified brain circuits that help determine how fear responses change as perceived threats diminish, offering new insight into how the brain regulates defensive ...

The targeted modulation of gene activity and cellular signaling pathways could provide a new approach to the treatment of fear and anxiety states according to the recent findings of a project ...

Overall, the findings of this recent study suggest that psilocybin promotes fear extinction (i.e., the unlearning of fearful responses to neutral stimuli previously associated with threats) via the ...

Dangers come but dangers also go and when they do, the brain has an “all-clear” signal that teaches it to extinguish its fear. A new study in mice by MIT neuroscientists shows that the signal is the ...
