To Flee or Freeze? Neural Circuits of Threat Detection Identified

Suddenly something streaks into your peripheral vision.  Instantly, you jump back and raise your arms defensively.  “What was that!” You exclaim in shock.   Only then do you realize that the blurred streak you just dodged was a wayward basketball zinging like a missile on a collision course for your face.  A rush of adrenaline flushes through your blood setting your heart pounding and muscles twitching, but there is nothing left to do.  Your brain’s rapid response defense system has already detected the threat and avoided it before your conscious mind is even engaged.  How is that possible, scientist, Peng Cao and colleagues of the Chinese Academy of Sciences wondered?

What Color is Distress?

Social media has been on fire with a debate – not over ISIS, healthcare or global warming – but over the perceived color of a dress. The dress provides a unique opportunity to consider two big questions at the interface of philosophy, neuroscience and psychophysics: is there an objective reality, and do we all experience it the same way? You may see the dress differently when you see it next.
