      Background: There are a few studies showing no significant heart rate variability (HRV) over a 24-hour period in vasovagal syncope (VVS) patients, but no research has examined HRV and its sympathetic and parasympathetic ...

    • Increased hypocretin-1 levels in cerebrospinal fluid after REM sleep deprivation 

      Pedrazzoli, M.; D'Almeida, V; Martins, PJF; Machado, R. B.; Ling, L.; Nishino, S.; Tufik, S.; Mignot, E. (Elsevier B.V., 2004-01-02)

      Machado, Ricardo Borges [UNIFESP]; Suchecki, Deborah [UNIFESP] (Frontiers Media Sa, 2016)
      Sleep homeostasis depends on the length and quality (occurrence of stressful events, for instance) of the preceding waking time. Forced wakefulness (sleep deprivation or sleep restriction) is one of the main tools used for ...
