Coordinates (x, y, z) are expressed in millimeter in the Montreal Neurological Institute (MNI); Z scores result from the statistical parametric analysis; pSVC refers to the probability of the null hypothesis (i.e., absence of activity change associated with tones in deep NREM sleep), after correction for multiple comparisons either on the whole brain volume (*) or on small volumes of interest identified in the literature (references in brackets).
