A new study links repeated binge drinking to persistent brain inflammation that reshapes mood, fear learning, and relapse ...

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 ...

To expand the understanding of memory, a research team has developed a technology called LCD-eGRASP (local circuit dual-eGRASP) that can label synapses of neural circuits within a specific brain ...

Anxiety is no longer being viewed merely as a psychological feeling of fear or unease. Increasingly, neurologists and endocrinologists are describing it as a "neuroendocrine imbalance," a problem ...

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 ...

Scientists are discovering that our tendency to develop certain phobias might be written in our DNA before we even encounter the things that terrify us. Evidence from twin studies suggests that ...

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 ...

In normal mice, after a traumatic event, the synaptic network complex and excitability of basal amygdala excitatory neurons increase, which activates the basal amygdala, facilitating the extinction of ...

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 ...
