EEG theta power during Necker cube reversals
… a proposed neurophysiological model for Necker cube reversals by using electroencephalography. It is suggested that Necker cube reversals are mediated by sustained focused attention to the overall drawing with visual selective attention to vertices of the cube. The main hypotheses were …

Zerebrale Verarbeitung optischer Multistabilität, eine Untersuchung mittels ereigniskorrelierter Potentiale
… 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 …

Transitions-felt: William James, Locative Narrative and the Multi-stable Field of Expanded Narrative
… we look at an ambiguous figures, such as, the Necker cube, this thesis develops the position that expanded narrative practices and specifically locative narrative, a genera of expanded narrative, hold the potential to prompt the experiential effects of multi-stability. The metaphor of …

On the fate and consequences of conscious and non-conscious vision
… with multi-stable phenomena (i.e, as with the Necker cube) or when subjects are presented with dissimilar images to each eye, a condition called binocular rivalry. Without a functioning visual brain we are not able to properly see. Lesions to the visual cortex produce a wide variety of visual …

Wahrnehmungswechsel bei mehrdeutigen Bildern - EEG-Messungen zum Zeitverlauf neuronaler Mechanismen
Die Betrachtung mehrdeutiger Reize (z.B. Necker-Würfel) führt zu spontanen Wahrnehmungswechseln. In bisherigen EEG-Untersuchungen zu diesem Phänomen wurde der Tastendruck der Versuchsperson als Referenz zur Mittelung genutzt, was zu hoher zeitlicher Ungenauigkeit führt. Mit einem verfeinerten …
