We investigated the reliability of nodal network metrics of functional connectivity (FC) networks of magnetoencephalography (MEG) covering the whole brain at the sensor level in the eyes-closed (EC) and eyes-open (EO) resting states. Mutual information (MI) was employed as a measure of FC between sensors in theta, alpha, beta, and gamma frequency bands of(More)
It is not clear whether specific brain areas act as hubs in the eyes-closed (EC) resting state, which is an unconstrained state free from any passive or active tasks. Here, we used electrophysiological magnetoencephalography (MEG) signals to study functional cortical hubs in 88 participants. We identified several multispectral cortical hubs. Although(More)
BACKGROUND The issue of how differences in timbre are represented in the neural response still has not been well addressed, particularly with regard to the relevant brain mechanisms. Here we employ phasing and clipping of tones to produce auditory stimuli differing to describe the multidimensional nature of timbre. We investigated the auditory response and(More)

Recent studies have reported that early right anterior negativity (ERAN) and its magnetic counterpart (ERANm) are evoked by harmonic irregularity in Western tonal music; however, those studies did not control for differences of melody. Because melody and harmony have an interdependent relationship and because melody (in this study melody is represented by(More)
19 We investigated the reliability of nodal network metrics of functional connectivity (FC) 20 networks of MEG covering the whole brain at the sensor level in the eyes-closed (EC) and 21 eyes-open (EO) resting states. Mutual information (MI) was employed as a measure of FC 22 between sensors in theta, alpha, beta, and gamma frequency bands of MEG signals.(More)
Aberrant cortical-striatal-thalamic-cortical circuits have been implicated in the pathophysiology of obsessive-compulsive disorder (OCD). However, the neurobiological basis of OCD remains unclear. We compared patterns of functional connectivity in patients with OCD and in healthy controls using resting-state magnetoencephalography (MEG). Participants(More)
