“…Rolandic rhythms were first described by Jasper and Andrews [Jasper and Andrews,1936], and since then the nomenclature has varied among researchers, e.g. the term “mu rhythm” has sometimes been applied to the Rolandic alpha rhythm, and sometimes to both rhythms [Tiihonen et al,1989].…”

“…Both rhythms are suppressed during tactile stimulation [Cheyne et al,2003] or voluntary phasic muscle activity [Jasper and Andrews,1936; Jasper and Penfield,1949; Pfurtscheller and Aranibar,1980; Pfurtscheller and Berghold,1989] and are enhanced by visual stimulation [Brechet and Lecasble,1965; Jasper and Andrews,1938; Koshino and Niedermeyer,1975]. However, Rolandic alpha and beta rhythms are not always modulated in parallel and their spatial distribution differs, with the beta rhythm being spatially more widespread distributed than the alpha rhythm [Magnus,1954].…”

In mammals, the development of individual behavioral profiles can be influenced considerably by social factors during early phases of life. In guinea pigs, for instance, sons whose mothers experienced social instability during pregnancy and lactation show an infantilized behavioral profile. Here, we examined whether the same phenomenon exists also in wild cavies, the ancestor of the domestic guinea pig. Using a comparable experimental approach, our results revealed a similar behavioral infantilization as well as a delayed gonadal development of sons when their mothers had lived under unstable social conditions. These data show clearly that the behavioral and hormonal profile of male wild cavies can be shaped significantly by the social environment in which their mothers lived during pregnancy and lactation. Hence the underlying mechanisms cannot have been brought about by artificial selection during domestication. Rather, they represent maternal effects evolved through natural selection adjusting the offspring to the current environmental conditions. © 2011 Wiley Periodicals, Inc.

“…Previous studies have shown that the posterior alpha rhythm can be obtained from EEG recorded during and/or between MRI data acquisition, and that the signal-to-noise ratio of the EEG is sufficient to use the power of the alpha rhythm as a regressor for modeling of the fMRI data [Feige et al, 2005]. In this study, we extend this approach to Rolandic rhythms with amplitudes markedly smaller than those of the posterior alpha rhythm (8-25 lV when compared to 20-60 lV [Jasper and Andrews, 1936]. Nevertheless, gradient artifact correction made it possible to recover these rhythms with their major features, such as pericentral topography, motor-task reactivity and spectral predominance in the alpha and beta band.…”

Similar to the posterior alpha rhythm, pericentral (Rolandic) EEG rhythms in the alpha and beta frequency range are referred to as "idle rhythms" indicating a "resting state" of the respective system. The precise function of these rhythms is not clear. We used simultaneous EEG-fMRI during a bimanual motor task to localize brain areas involved in Rolandic alpha and beta EEG rhythms. The identification of these rhythms in the MR environment was achieved by a blind source separation algorithm. Rhythm "strength", i.e. spectral power determined by wavelet analysis, inversely correlated most strongly with the fMRI-BOLD signal in the postcentral cortex for the Rolandic alpha (mu) rhythm and in the precentral cortex for the Rolandic beta rhythm. FMRI correlates of Rolandic alpha and beta rhythms were distinct from those associated with the posterior "classical" alpha rhythm, which correlated inversely with the BOLD signal in the occipital cortex. An inverse correlation with the BOLD signal in the respective sensory area seems to be a general feature of "idle rhythms".
