Abstract: Sustained selective visual attention is a remarkable cognitive ability that enables us to concentrate on specific visual stimuli for extended periods, effectively ignoring irrelevant or distracting information. This ability plays a crucial role in tasks demanding continuous concentration, such as reading, studying visual materials, and analyzing complex visual data. In this study, we devised a novel method for assessing sustained visual attention using bistable images as a paradigm. Our approach revolves around the human imaginative perception of the Necker cube orientation. Through careful analysis of MEG and EEG signals, we successfully identified frequency tags in the visual cortex that correlated with participants' attention performance. Interestingly, we made a fascinating discovery – a positive correlation between heightened attention and increased brain noise, challenging conventional notions of brain function. These findings not only deepen our understanding of attentional processes but also hold great promise for future research and interventions aimed at enhancing visual attention abilities. Furthermore, our refined approach holds tremendous potential for the development of groundbreaking brain-computer interfaces and brain-to-brain interfaces that leverage ambiguous visual stimuli, facilitating the mental control of external devices and enabling seamless communication between individuals.
