Un sistema a microprocessore per il riconoscimento automatico del sonno delta e della secrezione notturna dell'ormone della crescita

The close temporal relationship between nocturnal hGH release and Delta Sleep (stage 3 and 4) is well known. In order to overcome the practical difficulties in nocturnal hormonal study for clinical routine, an automatic processing system has been proposed to detect delta sleep on-line. Eight adult volunteers and ten children were studied: hGH (human Growth Hormone) samples were drawn during sleep, evaluated by a poligraphic EEG recording with the usual criteria and simultaneously Analyzed by the automatic system.
