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 ...

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 ...

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 ...

A team of researchers has shown that noninvasive electrical stimulation of the vagus nerve through the ear can reverse memory deficits caused by acute stress in mice, pinpointing a specific protein ...

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 ...
