“…The source of the attentional control signal is considered to originate from frontal and parietal areas [24,[40][41][42], consistent with the present result. In addition, we have previously provided evidence for a separable but linked system by investigating attentional modulation of evoked responses in a visualtactile cross-modal sustained attention task [39,43]. We thus propose a hybrid system including a separable-but-linked system for stimulus processing and an attentional control system.…”

Previous studies have demonstrated task-related changes in brain activation and inter-regional connectivity but the temporal dynamics of functional properties of the brain during task execution is still unclear. In the present study, we investigated task-related changes in functional properties of the human brain network by applying graph-theoretical analysis to magnetoencephalography (MEG). Subjects performed a cue-target attention task in which a visual cue informed them of the direction of focus for incoming auditory or tactile target stimuli, but not the sensory modality. We analyzed the MEG signal in the cue-target interval to examine network properties during attentional control. Cluster-based nonparametric permutation tests with the Monte-Carlo method showed that in the cue-target interval, beta activity was desynchronized in the sensori-motor region including premotor and posterior parietal regions in the hemisphere contralateral to the attended side. Graph-theoretical analysis revealed that, in beta frequency, global hubs were found around the sensori-motor and prefrontal regions, and functional segregation over the entire network was decreased during attentional control compared to the baseline. Thus, network measures revealed task-related temporal changes in functional properties of the human brain network, leading to the understanding of how the brain dynamically responds to task execution as a network.

“…The baseline correction was performed using the prestimulus samples. In the present study, neural responses to the visual single-pulse stimulus (frequently pre-sented stimulus) were analyzed to see a pure spatial selective attentional effect on visual-evoked responses (Garcia-Larrea et al 1995;Kida et al 2004Kida et al , 2007. The large noise included in the recorded signal was removed using the signal space projection (SSP) technique and then the data were filtered off-line with a low-pass filter of 50 Hz.…”

“…Behavioral studies have revealed such links in attention among vision, audition, and touch (Lloyd et al 2003;Driver 1996, 1997;Spence et al 2000Spence et al , 2004. Consistent with these findings, there is growing evidence for the neural system underlying the cross-modal links (Chambers et al 2004;Eimer and Driver 2000;Kida et al 2007;Macaluso et al 2000b;McDonald et al 2003;Teder-Salejarvi et al 1999). Functional magnetic resonance imaging (fMRI) has revealed bimodal activation in the intraparietal sulcus and temporoparietal junction during spatial attention tasks, suggesting the involvement of these regions in the cross-modal links (Macaluso et al 2000a,b).…”

“…The present study measured the gradient of magnetic fields and performed the source analysis to demonstrate whether modality-specific cortex actually contributes to the similarity of attentional modulations. The data on tactile-evoked responses have been published elsewhere (Kida et al 2007).…”

“…Eimer and colleagues (Eimer and Driver 2000; Eimer and Schroger 1998; Eimer et al 2002Eimer et al , 2004 have extensively studied the time course of neural activity related to the links among different senses including vision, touch, and audition. Our previous study used magnetoencephalography (MEG) to demonstrate that the link from vision to touch is represented by neural activity in the upper wall of the sylvian fissure at about 80 ms after tactile stimuli as well as the effect of within-modal spatial attention (Kida et al 2007). However, the spatiotemporal dynamics of cortical processes underlying the cross-modal links in the visual system is incompletely understood.…”

Kida T, Inui K, Tanaka E, Kakigi R. Dynamics of within-, inter-, and cross-modal attentional modulation. J Neurophysiol 105: 674 -686, 2011. First published December 8, 2010 doi:10.1152/jn.00807.2009. Numerous studies have demonstrated effects of spatial attention within single sensory modalities (within-modal spatial attention) and the effect of directing attention to one sense compared with the other senses (intermodal attention) on cortical neuronal activity. Furthermore, recent studies have been revealing that the effects of spatial attention directed to a certain location in a certain sense spread to the other senses at the same location in space (cross-modal spatial attention). The present study used magnetoencephalography to examine the temporal dynamics of the effects of within-modal and cross-modal spatial and intermodal attention on cortical processes responsive to visual stimuli. Visual or tactile stimuli were randomly presented on the left or right side at a random interstimulus interval and subjects directed attention to the left or right when vision or touch was a task-relevant modality. Sensor-space analysis showed that a response around the occipitotemporal region at around 150 ms after visual stimulation was significantly enhanced by within-modal, cross-modal spatial, and intermodal attention. A later response over the right frontal region at around 200 ms was enhanced by within-modal spatial and intermodal attention, but not by cross-modal spatial attention. These effects were estimated to originate from the occipitotemporal and lateral frontal areas, respectively. Thus the results suggest different spatiotemporal dynamics of neural representations of cross-modal attention and intermodal or within-modal attention. I N T R O D U C T I O NAttention is often directed to sensory signals coming from different senses in the same space. However, previous studies have traditionally focused on the effect of spatial attention within single sensory modalities (within-modal spatial attention) (Hillyard et al. 1987;Luck et al. 1990;Mangun and Hillyard 1990;Martinez et al. 1999;Muller et al. 1998;Poghosyan and Ioannides 2008;Schoenfeld et al. 2003). Some studies have reported attentional modulation of visual processing when attention was directed to vision compared with when it was directed the other senses (intermodal selective attention) (de Ruiter et al. 1998; Eimer and Schroger 1998;Hackley et al. 1990; Kok 2001, 2002;Woods et al. 1992). The intermodal studies have suggested the contribution of modalityspecific brain areas to the effect of intermodal attention (Eimer and Schroger 1998;Talsma and Kok 2001;Woods et al. 1992) and similar effects of intermodal and within-modal attention (Talsma and Kok 2001). The effects of intermodal and withinmodal attention have also been observed in single-unit and multiunit recordings in the visual cortex of monkeys (Luck et al. 1997; Mehta et al. 2000a,b).Furthermore, it remains a matter of debate whether the effect of attention on cortical processing spreads across ...

The detailed time courses of cortical activities and source localizations following passive finger movement were studied using whole-head magnetoencephalography (MEG). We recorded motor-related cortical magnetic fields following voluntary movement and somatosensory-evoked magnetic fields following passive movement (PM) in 13 volunteers. The most prominent movement-evoked magnetic field (MEF1) following active movement was obtained approximately 35.3 ± 8.4 msec after movement onset, and the equivalent current dipole (ECD) was estimated to be in the primary motor cortex (Brodmann area 4). Two peaks of MEG response associated with PM were recorded from 30 to 100 msec after movement onset. The earliest component (PM1) peaked at 36.2 ± 8.2 msec, and the second component (PM2) peaked at 86.1 ± 12.1 msec after movement onset. The peak latency and ECD localization of PM1, estimated to be in area 4, were the same as those of the most prominent MEF following active movement. ECDs of PM2 were estimated to be not only in area 4 but also in the supplementary motor area (SMA) and the posterior parietal cortex (PPC) over the hemisphere contralateral to the movement, and in the secondary somatosensory cortex (S2) of both hemispheres. The peak latency of each source activity was obtained at 54–109 msec in SMA, 64–114 msec in PPC, and 84–184 msec in the S2. Our results suggest that the magnetic waveforms at middle latency (50–100 msec) after PM are different from those after active movement and that these waveforms are generated by the activities of several cortical areas, that is, area 4 and SMA, PPC, and S2. In this study, the time courses of the activities in SMA, PPC, and S2 accompanying PM in humans were successfully recorded using MEG with a multiple dipole analysis system.
