“…Axmacher et al (2010) showed that maintenance of multiple items is associated with hippocampal thetagamma cross-frequency coupling and that the modulating theta frequency depends on memory load. Theta-gamma phase synchronization during performance on visual working memory tasks has also been reported for healthy subjects (Holz, Glennon, Prendergast, & Sauseng, 2010;Schack, Vath, Petsche, Geissler, & Möller, 2002). Further, Kamiński, Brzezicka, and Wróbel (2011) demonstrated that short term memory capacity can be predicted by theta-to-gamma cycle length ratio.…”

“…Considering the powerful coupling (Whitman et al 2013) between *7 Hz and *40-45 Hz (20-25 ms intervals) frequency bands that mediate information between the hippocampal formation deep within the temporal lobes and its representation within the cerebral cortices (Holz et al 2010), this particular congruence of oscillations is directly relevant to subtle influences of ''infrasound'' upon consciousness and the ''memory'' of events. It may be relevant that parallel timing across levels of discourse appears to define biological systems from a physical perspective.…”

Infrasound displays a special capacity to affect human health and adaptation because its frequencies and amplitudes converge with those generated by the human body. Muscle sounds and whole-body vibrations are predominately within the 5-to 40-Hz range. The typical amplitudes of the oscillations are within 1-50 lm, which is equivalent to the pressures of about 1 Pa and energies in the order of 10 -11 W m -2 . Infrasound sources from the natural environment originate from winds, microbaroms, geomagnetic activity, and microseisms and can propagate for millions of meters. Cultural sources originate from air moving through duct systems within buildings, large machinery, and more recently, wind turbines. There are also unknown sources of infrasound. It is important to differentiate the effects of infrasound from the awareness or experience of its presence. Moderate strength correlations occur between the incidences of infrasound and reports of nausea, malaise, fatigue, aversion to the area, non-specific pain, and sleep disturbances when pressure levels exceed about 50 db for protracted periods. Experimental studies have verified these effects. Their validity is supported by convergent quantitative biophysical solutions. Because cells interact through the exchange of minute quanta of energy that corresponds with remarkably low levels of sound pressure produced by natural phenomena and wind turbines upon the body and its cavities, traditional standards for safety and quality of living might not be optimal.

“…Using the Lisman and Idiart [39] model as a guide, we might expect to find generally reduced phase-phase coupling between theta-and gamma-activity during performance of tasks probing WM in PSZ. Theta-gamma coupling in healthy people has been observed prominently over prefrontal and posterior regions in scalp level recordings [32,35,36,[68][69][70]. Thus, deficits in synchrony between the two bands observed over anterior and posterior regions in scalp recordings, as well as in theta-gamma synchrony between the two areas, would particularly support the notion that deficits in the temporal alignment of theta-and gamma-activities are inextricably linked to WM function in the disorder.…”

Working memory (WM) deficits have been repeatedly observed in people with schizophrenia (PSZ) and their unaffected biological relatives (REL). Given the apparent association with genetic liability for schizophrenia, WM deficits have been proposed as a potential endophenotype for the disorder. Abnormal neural responses during WM performance have likewise been observed in PSZ and REL and may reflect the expression of genetic liability for schizophrenia in brain function. Relatively recent investigations have examined the role of neural oscillatory activity during visuospatial WM function in healthy people, as well as dysfunction in psychopathology. This research was in part motivated by a neural model of WM proposed by Lisman and Idiart (Science 267:1512(Science 267: -1515(Science 267: , 1995 that delineated a mechanism for representing multiple stimuli within WM through systematic interactions between neural oscillations in the theta-and gamma-frequency ranges. Aberrant oscillatory activity in theta and gamma frequency ranges has since been proposed as a potential underlying factor in WM dysfunction in PSZ and REL. The experimental evidence derived from studies of healthy people that pertains to the theta-gamma model of WM is reviewed herein. Although scarce, direct examinations of theta-gamma interactions in PSZ and REL are likewise reviewed in addition to reports of separate deficits in theta and gamma frequencies observed in PSZ during WM. The implications of theta and gamma oscillatory deficits reported in PSZ are discussed in the context of the Lisman and Idiart (Science 267:1512(Science 267: -1515(Science 267: , 1995 model, as well as how these deficits may result in aberrant theta-gamma interactions that give rise to visuospatial WM dysfunction. Given evidence supporting the Lisman and Idiart (Science 267:1512(Science 267: -1515(Science 267: , 1995 model of theta-gamma interactions in WM and the lack of direct exploration of the model in schizophrenia, there is an imperative to carry out formal testing of theta-gamma interactions in PSZ and REL during WM.
