Topic: bilateral alternating stimulations

The aim of this study is to compare and explore the frequency characteristics of non-ordinary states of consciousness (NSCs) induced by hypnosis and bilateral alternating stimulations (BAS) as used in EMDR and the depth of these states. The neurophysiological processes underlying these states are investigated by measuring power spectral density (PSD) in frequency bands of the EEG signal and the deepness of NSC is assessed through visual analog scales on intensity, absorption, dissociation and immersion during memory recall. 25 healthy participants were included in the study. Each participant w
