The purpose of this study was to clarify the relationships between the distributions and cortical sources of two types of spindles in the magnetoencephalogram (MEG) and how cortical activating areas contribute to the distribution of spindles. Spontaneous activities during sleep stage 2 were recorded from 7 normal subjects by simultaneous EEG and MEG… (More)
Few methods can predict the prognosis and outcome of traumatic brain injury. Electroencephalographic (EEG) examinations have prognostic significance in the acute stage of posttraumatic coma, and some EEG variables have been correlated with outcome. Furthermore, spindle activity and reactivity in the acute stage have been associated with good recovery.… (More)

This study aimed to determine the relationships between the amplitude and cortical-activating areas in each hemisphere for 14-Hz centro-parietal spindles to clarify the involvement of the cortex in the asymmetry of spindles after hemispheric stroke with putaminal or thalamic hemorrhage using simultaneous recording of the electroencephalogram and… (More)
