New research identifies potential PTSD treatment improvement

Researchers may have found a way to improve a common treatment for post-traumatic stress disorder (PTSD) by changing how the brain learns to respond less severely to fearful conditions, according to research published in ...

Neuroscience

Scientists show how brain circuit generates anxiety

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) have identified a neural circuit in the amygdala, the brain's seat of emotion processing, that gives rise to anxiety. Their insight has revealed the critical role of ...

Learning and unlearning to fear: The two faces of noradrenaline

Emotional learning can create strong memories and powerful emotional responses, but flexible behavior demands that these responses be inhibited when they are no longer appropriate. Scientists at the RIKEN Brain Science Institute ...

Neuroscience

Researchers show how particular fear memories can be erased

Researchers at the University of California, Riverside have devised a method to selectively erase particular fear memories by weakening the connections between the nerve cells (neurons) involved in forming these memories.
