Open AccessA magnetoencephalography dataset during three-dimensional reaching movements for brain-computer interfaces
Studying the motor-control mechanisms of the brain is critical in academia and also has practical implications because techniques such as brain-computer interfaces (BCIs) can be developed based on brain mechan...

Open AccessStructural and functional thalamocortical connectivity study in female fibromyalgia
Dysfunctional thalamocortical interactions have been suggested as putative mechanisms of ineffective pain modulation and also suggested as possible pathophysiology of fibromyalgia (FM). However, it remains unc...

Open AccessCharacterization of kinesthetic motor imagery compared with visual motor imageries
Motor imagery (MI) is the only way for disabled subjects to robustly use a robot arm with a brain-machine interface. There are two main types of MI. Kinesthetic motor imagery (KMI) is proprioceptive (OR somato...

Open AccessBrain mechanisms in motor control during reaching movements: Transition of functional connectivity according to movement states
Understanding how the brain controls movements is a critical issue in neuroscience. The role of brain changes rapidly according to movement states. To elucidate the motor control mechanism of brain, it is esse...

Open AccessDisrupted Resting State Network of Fibromyalgia in Theta frequency
Fibromyalgia (FM), chronic widespread pain, exhibits spontaneous pain without external stimuli and is associated with altered brain activities during resting state. To understand the topological features of br...

Open AccessTactile Frequency-Specific High-Gamma Activities in Human Primary and Secondary Somatosensory Cortices
Humans can easily detect vibrotactile stimuli up to several hundred hertz, but underlying large-scale neuronal processing mechanisms in the cortex are largely unknown. Here, we investigated the macroscopic neu...

Open AccessFormation of visual memories controlled by gamma power phase-locked to alpha oscillations
Neuronal oscillations provide a window for understanding the brain dynamics that organize the flow of information from sensory to memory areas. While it has been suggested that gamma power reflects feedforward...

Open AccessIntraindividual neurophysiological variability in ultra-high-risk for psychosis and schizophrenia patients: single-trial analysis
Intraindividual variability in neurophysiological responses is an important factor in the study of schizophrenia. Interestingly, this variability strongly predicts individual differences in cognitive processin...

Open AccessA study on a robot arm driven by three-dimensional trajectories predicted from non-invasive neural signals
A brain-machine interface (BMI) should be able to help people with disabilities by replacing their lost motor functions. To replace lost functions, robot arms have been developed that are controlled by invasiv...

Open AccessPower spectral aspects of the default mode network in schizophrenia: an MEG study
Symptoms of schizophrenia are related to deficits in self-monitoring function, which may be a consequence of irregularity in aspects of the default mode network (DMN). Schizophrenia can also be characterized b...

Open AccessImpaired coupling of local and global functional feedbacks underlies abnormal synchronization and negative symptoms of schizophrenia
Abnormal synchronization of brain oscillations is found to be associated with various core symptoms of schizophrenia. However, the underlying mechanism of this association remains yet to be elucidated.

Open AccessResection frequency map after awake resective surgery for non-lesional neocortical epilepsy involving eloquent areas
The resection of eloquent areas is challenging due to postoperative neurological deficits. The purpose of this study was to assess the efficacy and risk of awake brain surgery for non-lesional epilepsy involvi...

Real-time volume rendering of four-dimensional images based on three-dimensional texture map**
A four-dimensional (4-D) image consists of three-dimensional (3-D) volume data that varies with time. It is used to express a deforming or moving object in virtual surgery or 4-D ultrasound. It is difficult to...

Adaptable fuzzy C-Means for improved classification as a preprocessing procedure of brain parcellation
Parcellation, one of several brain analysis methods, is a procedure popular for subdividing the regions identified by segmentation into smaller topographically defined units. The fuzzy clustering algorithm is ...
