摘要：

Neural Information Flow during simple cognitive or motor actions is very recent research topic. One of the simple movements to be studied is a simple finger movement. In this paper, Electro-encephalograph (EEG) Source Imaging has been used to model the Neural Information flow, during performance of a simple Auditory Response Task (ART). The estimated sources are firstly divided into separate scouts according to the Destrieux Atlas. Then, relative power carried in each scout at each instant has been used to create a neural information flow map. Another key feature of this paper lies in the fact that the database corresponded of subjects performing a group of tasks repetitively until significant drop in vigilance. This provides a unique point of view, as to how drop in vigilance levels affect the Neural Information flow. The results show a correlation between trends reflected in EEG parameters and performance scores of neuropsychological tests.
