Research on the effect of sleep deprivation (SD) is an approach to shedding light on the working mechanism of sleep for cognitive brain function. To explore how SD affects cognitive function, a number of measures involving psychology, brain imaging and electrophysiology, have been adopted in this area. Research groups from domestic and verseas have focused(More)
The aim of this study was to confirm the character of EEG and the location in brain when a person was enjoying different rhythm music. It made the subjects excited when they enjoyed different rhythm music, the EEG signals are collected with Phoenix Digital EEG with 128 channels, and compared with the ones before the subjects enjoying the music. Obvious(More)
Transcranial magnetic stimulation (TMS) is a new tool for the study of the human brain and for neurological therapeutics. Magnetic coil design is very important in the TMS technique. Precise spatial localization of stimulation sites is the key of efficient functional magnetic stimulations. This paper develops circular coils, figure-of-8 coils and coil array(More)
At present, young people's internet addiction has become a serious social problem and on important concern in China. Comparison studies of auditory event-related potential (ERP) between 9 excessive internet users and 9 common internet users were carried out. The obvious influences of excessive internet use on the users were observed. The result suggests(More)
This investigation was made on the characteristic of the N400 event-related potentials in excessive internet users by analyzing the N400 difference between the excessive internet users (trial team) and normal subjects (control team); the aim was to provide a theoretic basis for the diagnosis and treatment of excessive internet users. Ten right-handed(More)
Quantification of rehabilitation progress is necessary for accurately assessing clinical treatments. A three-dimensional (3D) biomechanical model of the upper extremity was developed for quantification of stroke rehabilitation. The model was designed to accurately track the 3D orientation of the trunk, shoulder, elbow and wrist. This study explains the(More)
Electrical impedance tomography is a new imaging modality that produces images by computing electrical conductivity within the body. This paper presents a basic acquisition hardware system of Electrical Impedance Tomography with direct digital synthesis (DDS), which is used for studying the human head electrical property. The filtered back-projection(More)
Identification and classification technology plays an important part in study of the BCI system. There are many algorithms to classify the event of different task related. Here, finger movement was used as the basic and typical tasks to be identified in the BCI experiments. The ideas of BP and ERD were introduced and discussed. The CSSD (common spatial(More)
A specially-designed time-varying magnetic field was developed to treat insomnia. Clinical results showed that this method could shorten the time to go to sleep and prolong the sleep duration. However, the mechanism of this method is still not well understood. In this study, the effect of magnetic stimulation on the release of serotonin (5-HT),(More)
Left and right hand movement imagery can modifty the neural activity in the primary sensorimotor areas in a very similar way as observable with a real executed movement, leading to the special changes of EEG components such as event-related desynchronization/synchronization (ERD/ERS). Quick and correct classification of these event-related EEG pattern can(More)
