How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

An ambiguous figure such as the Necker cube causes spontaneous perceptual switching (SPS). The mechanism of SPS in multistable perception has not yet been determined. Although early psychological studies suggested that SPS may be caused by fatigue or satiation of orientation, the neural mechanism of SPS is still unknown. Functional magnetic resonan...

Previous effective connectivity analyses of functional magnetic resonance imaging (fMRI) have revealed dynamic causal streams along the dorsal attention network (DAN) during voluntary attentional control in the human brain. During resting state, however, fMRI has shown that the DAN is also intrinsically configured by functional connectivity, even i...

The 4-12 Hz (theta rhythm)-dependent neural dynamics play a fundamental role in the memory formation of the rat hippocampus. Although the power of human scalp electroencephalography theta (EEG theta) is known to be associated with a hippocampus-dependent memory encoding, it remains unclear whether the human hippocampus uses theta rhythm. In this st...
Article
Previous studies with effective connectivity analysis have revealed neural streams of orienting of attention. However, neural streams involved in holding of attention on the fovea remain unclear. To identify them, we performed event-related functional MRI with a cueing paradigm and Granger causality analysis. Typical regions along the dorsal attent...
Article
Neural correlates of reorienting across visual hemifields have been extensively studied, however, those of reorienting within hemifields and if there are any differences remain unclear. Here, we performed a functional magnetic resonance imaging study to identify neural correlates of reorienting within and across hemifields using a variant of the cu...

We investigated top-down selective attentional modulation of bistable perception. Sixteen healthy human observers were presented with the Necker cube on a black background. Observers reported perceptual switches between two possible interpretations by pressing one of two keys. Observers were instructed either to passively view the Necker cube or to...
