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 ...

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 ...

Unlearning fear responses is a fundamental learning process in the brain. It allows us to flexibly react to formerly threatening situations once the danger is no longer present. This mechanism, known ...

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 ...

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 ...

Researchers discovered that PTSD may be driven by excess GABA from astrocytes, not neurons. This chemical imbalance disrupts the brain’s ability to forget fear. A new drug, KDS2010, reverses this ...

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 ...
