An article published in the journal Current Biology describes experiments that mapped a brain circuit responsible for instantly detecting threats and forming memories of fear. "We were interested in ...

Anxiety disorders (like social anxiety) and stress disorders (like PTSD) are among the most common mental health diagnoses with a lifetime prevalence of almost 30%. New technologies like fMRI, which ...

In new research, Boston University neuroscientist Dr. Steve Ramirez and collaborators examine the dynamic nature of fear responses in varied environments and their impacts Beyond its implications for ...

Deleting a gene called PTEN in certain brain cells disrupts the brain’s fear circuitry and triggers anxiety-like behavior in mice — key traits seen in autism. Researchers mapped how this genetic tweak ...

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 ...

Nk3R antagonism decreases fear memory consolidation. (A) Experimental procedure of fear memory consolidation after stress. Created with Biorender. (B) Fear acquisition and expression in mice ...

Schematic model showing how memory is consolidated in the prefrontal cortex and how circuitry through the amygdala shifts as hippocampal engram cells become silent and cortical engrams become active.

Autism spectrum disorder (ASD) is widely known for its core features, which include difficulties in social communication and repetitive behaviors. But beyond these, many individuals with ASD also ...
