Across the long arc of human history, every unfamiliar shelter has carried the quiet threat of the unknown — and the brain, it turns out, has never forgotten this. Researchers at Nagoya University have identified the precise neural circuit in the extended amygdala responsible for the 'first night effect,' the near-universal experience of restless sleep in new environments. Neurons producing a chemical called neurotensine activate in unfamiliar settings, signaling the brain to remain on guard rather than surrender to deep rest. What travelers have long accepted as a minor inconvenience is, in f
