This study aimed to explore if the red light irradiation can affect the electrophysiology performance of flexor digitorum superficialis （FDS） and fatigue *** healthy volunteers were randomly divided into two *** the designed force-tracking tasks,all subjects performed the four fingertip isometric force production except thumb with a load of 30% of the maximum voluntary contraction （MVC） force until ***,for the red light group,red light irradiation （640 nm wavelength,0.23J/cm 2,20 min） was used on the right forearm;for the control group,the subjects relaxed without red light *** subjects were required to perform fatigue trail again,and sEMG signal was collected simultaneously from FDS during finger force *** rectified value （ARV） and median frequency （MF） of sEMG were *** to the control group,the red light irradiation induced more smoother value of ARV between 30% and 40%,and the value of MF was obviously large and *** above electrophysiological markers indicated that recovery from muscle fatigue may be positively affected by the red light irradiation,suggesting that sEMG would become a power tool for exploring the effect of red light irradiation on local muscle fatigue.

Neglected tropical diseases are a group of tropical diseases endemic in poor countries even though medical treatment and cures are available. They are considered a global health problem due to the severity of the physiological changes they induce in their hosts. Malaria is a disease caused by Plasmodium sp. that in its cerebral form may lead to acute or long-term neurological deficits, even with effective antimalarial therapy, causing vascular obstruction, reduced cerebral blood flow and many other changes. However, Plasmodium falciparum infection can also develop into a cerebral malaria(CM) disease that can produce neurological damage. This review will discuss the mechanisms involved in the neuropathology caused by CM, focusing on alterations in cognitive, behavior and neurological functions in human and experimental models.

＜正＞Objective The present study is to obtain correlation between spatially separated brain regions,as well as the changes in time and frequency domain through analysis of the magnetoencephalography *** By means of the theory of coherence analysis,coherence coefficient of two signals corresponding to different cortical areas is computed, which reflects synchronization of the above two signals,as well as the correlation between spatially separated brain *** frequency analysis is also used to discuss the cortical correlation changes co-vary closely with time over the course of motor task in the three frequency band-α,βand lowγ.Results（1） By computing the coherence coefficient relative to the selected reference channel,it is suggested that channels with the most significant coherence are approximately in the same area,*** contralateral primary motor cortex and premotor ***,with the increase of frequency band both the coherence coefficient and the coupled area decline.（2） Changes of coherence co-varing with time inα,βand lowγband present the following characteristic:①The coherence shows such a trend that it increases firstly and then decreases over the course of motor task.②The most significant coherence,forαband,is observed from 0 to 0.3 second,while forβand lowγit appears at -0.2 *** The changes of coherence inα,βand lowγbands suggest that there are different neuronal modulations in the contralateral primary motor *** this modulation covaries with time,which consequently reflects the changes of correlation between different brain regions in time and frequency domain.
