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 ...

Neuroscientists identify a CRF-neuron "switch" in the brain's BNST region that, when activated, allows for significantly faster unlearning of fear responses.

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, ...

Mice are experts at learning fears, and they're experts at unlearning them, too. But what allows these animals to push past their terror when something that was a ...

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 ...

Stress is the brain’s natural response to fear, but it often disrupts memory in the process, potentially impacting the possibility of memory loss. When preparing for a big presentation or taking a ...

LEFT IMAGE: Coronal section of the locus coeruleus with two different populations of cells labeled with green or purple-colored retrograde tracers from the amygdala or medial prefrontal cortex ...

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 ...
