Decomposition methods with applications in neuroscience (2009)
Abstract / truncated to 115 words
The brain is the most important signal processing unit in the human body. It is responsible for receiving, processing and storing information. One of the possibilities to study brain functioning is by placing electrodes on the scalp and recording the synchronous neuronal activity of the brain. Such a recording measures a combination of active processes in the whole brain. Unfortunately, it is also contaminated by artifacts. By extracting the artifacts and removing them, cleaned recordings can be investigated. Furthermore, it is easier to look at speciﬁc brain activities, like an epileptic seizure, than at a combination. In this thesis, we present diﬀerent mathematical techniques that can be used to extract individual contributing sources from the ... toggle 7 keywordsICA – CCA – PARAFAC – candecomp – multilinear – EEG – epilepsy
