oscillations , cross - frequency coupling , deep brain stimulation, source analysis, volume of tissue activated Introduction Deep brain stimulation (DBS) is a well-established treatment for alleviating motor ...
study the conditions for an effective communication between two coupled neural populations by systemically varying the interaction delay and mismatch of their natural oscillation frequencies . Our results ...
activity, i.e., temporarily couple together [4]. Notably, brain oscillations vary in frequencies depending on the task that is being executed and the region of the brain they are recorded from [3] (see Box 1 ...
), alpha (8–12 Hz), beta (13–25 Hz), to gamma (>25 Hz) frequency bands. Slower and faster rhythms interact by cross - frequency coupling [3]. The best-known type of such coupling is the phase–amplitude cross ...
frequency oscillations is often coupled to the phase of the low frequency (δ,θ) oscillations , forming the so-called cross - frequency phase–amplitude coupling (PAC) (Buzsáki and Draguhn 2004; Schroeder ...
, but for strong coupling they form a traveling wave. Glassy states with ordered, but uniformly distributed phases for each frequency also appear for distributed parameters [26], and for structured networks multiple ...
Introduction Oscillatory patterns of neuronal activity are reported in many brains regions with frequencies ranging from less than one Hertz to hundreds of Hertz. These oscillations are often ...
potential oscillations at many different characteristic frequencies are found all over the brain , often interacting within particular neural structures [45] and potentially serving to select and route ...
processes in the brain . The two units are coupled so that the action oscillator in one unit is unidirectionally linked to the perception oscillator in the other unit, through the external coupling term e ...
the generation of indirect PAC connections we may need to estimate other types of cross - frequency coupling such as APC, amplitude-amplitude coupling (AAC), and phase-phase coupling (PPC), as well as interactions ...
