The retrieval-extinction paradigm elicits a short-term fear amnesia that differs in cue specificity, timescale, and dependence on thought-control ability from the long-term amnesia believed to be ...

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 ...

Researchers have discovered a new way ribonucleic acid (RNA) impacts fear-related learning and memory. Researchers demonstrated that a noncoding RNA known as Gas5 coordinates the trafficking and ...

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 ...

A new study published in Nature Neuroscience provides a detailed look at how the psychedelic drug psilocybin facilitates the unlearning of fear in the brain. The research reveals that the drug does ...

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 reported progress in testing a new approach involving the dopamine system that they hope may help reduce symptoms of post-traumatic stress disorder (PTSD). Led by 2014 BBRF ...

Fear is a fundamental emotion necessary for survival. We experience fear in several ways that have helped humans stay alive, but it can go beyond what is appropriate for survival. Persistent fear and ...

Image showing activity-induced local expression of long noncoding RNA Gas5 in primary cortical neurons, in vitro. Red and blue indicate Gas5 and DAPI, respectively. Synaptic marker, PSD95 is labelled ...
