Zerebrale Verarbeitung optischer Multistabilität, eine Untersuchung mittels ereigniskorrelierter Potentiale

The change of depth perception (FLIP) of the rotating Necker cube prefers certain flip-positions when edges overlap. Thus it is possible to study FLIPs without necessarily instructing the subjects to indicate a FLIP by pressing of a button. In this experiment we studied electrophysiologic correlates of FLIPs. 9 right-handed subjects observed a standardized rotating necker cube while recording 96 channel EEG. Additional a fMRI study carried out. A fMRI-constrained minimum norm current density reconstruction calculated the electric activity of selected brain regions for every single epoch. Additional to averaging, a single epoch wavelet transform delivered the non phaselocked average in order to detect event related (de-)synchronisations.
