title: [Pain sensitivity during chronic psychoemotional stress in humans].
abstract: In a natural "model" of a chronic psychoemotional stress in humans, (neurasthenia) a decrease in the nociceptive threshold was found. The decrease resulting from weakening of supraspinal tonic descending inhibition which, in its turn, evidently was due to a diminished activity (or dysfunction) of the brain opioid system occurring in a long-lasting psychoemotional stress.
