Dr, Christos A. Frantzidis presented methodological steps towards a multi-parametric system of automated sleep scoring and the difficulties towards its realistic implementation. He also presented the identity of the RSL study which involved 23 healthy, young male volunteers. Then, he presented the Greek experiment which employed polysomnographic sleep recordings through 19 electrodes placed according to the 10-20 International System. Saliva measurement took also place. The EEG activity was recorded during baseline, 21, 35, 50 days after the initiation of the experimental period and during the recovery phase.
