Causal interaction between different brain regions has received wide attention recently. Granger causality (GC) is one of the most popular methods to explore causality relationship between different brain regions. New causality (NC) proposed by Hu et. al was shown to be better reveal true causality than GC. In this paper based on scalp EEGs from 6 groups subjects we apply GC and NC methods to study...
In [10] we proposed two methods to identify the reference signal under the key assumption that the reference signal is independent from EEG sources. This assumption may be true for intracranial EEG with a scalp reference. However, it may not be true for scalp sources with a scalp reference electrode. As such, this limits the application of our methods to the vast majority of scalp EEG with cephalic...
In this paper, we investigated the memorization variation during the observation of TV commercials by tracking the cortical activity. According to the priori knowledge, in the human scalp EEG, the theta band responds selectively to the encoding of new information into episodic memory. There will be a significantly larger increase in theta power during the memory encoding. Then we proposed a novel...
In our previous work [8] we proposed two methods to identify the reference electrode signal under the key assumption that the reference signal is independent from EEG sources. Although this assumption is shown to be possibly true for intracranial EEG with a scalp reference. However, this assumption may not be true for scalp sources with a scalp reference electrode. As such, this limits the application...
