Szukana fraza: [Abstract = "The role of relaxation oscillator models in application fields such as modeling dynamic systems and image analysis is discussed. A short review of the Van der Pol, Wilson\-Cowan and Terman\-Wang relaxation oscillators is given. The key property of such nonlinear oscillators, i.e., the oscillator phase shift \(called the Phase Response Curve\) as a result of external pulse stimuli is indicated as a fundamental mechanism to achieve and sustain synchrony in networks of coupled oscillators."]
