Cover Story: The balance between dissipative and nonlinear forces allows widespread traveling waves termed solitons to preserve their shape and energy for long distances without steepening and flattening out. We suggest that the electric oscillations detectable by scalp electroencephalography (EEG) could be assessed in terms of solitons. We argue that solitons bear striking similarities with the electric activity recorded for medical conditions like epilepsies and encephalopathies. Emerging from the noisy background of normal electric activity, high-amplitude, low-frequency EEG soliton-like waves with relatively uniform morphology and duration can be observed, characterized by repeated, stereotyped patterns propagating on the brain hemispheric surface over relatively large distances. The theoretical possibility of treating pathological brain oscillations using solitons is discussed in this paper. View this paper
