Beschreibung
Visual object representation is a prime example of the human brain's ability to efficiently and rapidly process highly complex and ambiguous information. Object processing has always been one of the central topics of cognitive neuroscience, but the swift and interactive neural mechanisms through which it is achieved are still not well understood. High frequency oscillatory activity, registered in the gamma-band of the human EEG, plays an important role in the perceptual organisation of a wide range of visual properties into coherent scenes.
The aim of the study was to demonstrate how such activity could be a possible mechanism subserving a range of processes crucial for visual object representation. Therefore, evoked and induced (i.e., not time- or phase-locked) gamma-band activity (GBA) were researched in a set of experiments that examined the mnemonic, perceptual and attentional side of visual object representation.
