Abstract

Sposób przetwarzania sygnału EEG, w którym odczytuje się sygnał EEG z dwóch elektrod czołowych (301) elektroencefalografu, konwertuje się odczytany sygnał do domeny częstotliwości i określa się wartości reakcji BIS/BAS na podstawie wartości asymetrii w domenie częstotliwości pomiędzy odczytanymi sygnałami, charakteryzuje się tym, że określa się wartości reakcji BIS/BAS na podstawie wartości asymetrii w domenie częstotliwości pomiędzy odczytanymi sygnałami w zakresie częstotliwości od 26 do 29 Hz. Ponadto, sposób przetwarzania sygnału EEG, w którym odczytuje się sygnał EEG z dwóch elektrod czołowych elektroencefalografu, konwertuje się odczytany sygnał do domeny częstotliwości i określa się wartości reakcji BIS/BAS na podstawie wartości asymetrii w domenie częstotliwości pomiędzy odczytanymi sygnałami, charakteryzuje się tym, że wartość asymetrii oblicza się jako różnicę pomiędzy znormalizowaną amplitudą dla jednej elektrody a znormalizowaną amplitudą dla drugiej elektrody.
