Abstract：
:Sensory, cognitive and motor processing can result in changes of the ongoing EEG in form of an event-related desynchronization (ERD) or event-related synchronization (ERS). Both phenomena are time-locked but not phase-locked to the event and they are highly frequency-band specific. The ERD is interpreted as a correlate of an activated cortical area with increased excitability and the ERS in the alpha and lower beta bands can be interpreted, at least under certain circumstances, as a correlate of a deactivated cortical area. Spatial mapping of ERD/ERS can be used to study the dynamics of cortical activation patterns. Examples from a movement task are reported.

VISION RESEARCH文献大全abstract：:While most studies on person recognition examine the face alone, recent studies have shown evidence for the contribution of the body and gait to person recognition beyond the face. Nevertheless, little is known on whether person recognition can be performed based on the body alone. In this study, we examined two sourc...
