" The mean conductance from current-to-voltage relationships obtained at the 29 Hz fundamental frequency showed strong nonlinearity, particularly a clear negative resistance region that we modelled with an Esaki diode current equation displaying a “tunnelling” effect that supports oscillatory function . The oscillatory behaviour in our study largely showed a 29 Hz fundamental frequency. Interestingly, several biological oscillatory phenomena prominently display 30 Hz cycles. Mechanical membrane oscillations in this frequency range and involving cytoskeletal structures, have been observed in various cell types [48,49]. Another relevant 30 Hz frequency phenomenon is present in the gamma cycle of the brain, the highest frequency brain wave type that ranges between 30–100 Hz . The gamma cycle has been associated with higher cognitive functions, including the formation of ideas, linguistic processing, various types of learning, and meditation [50,51]. Gamma waves have been linked to the cognitive act of processing and recall of memories [50,51] and are known to reversibly disappear during anaesthesia-induced deep sleep [52,53], a phenomenon attributed to changes in MT behaviour ."
