Automatic Onset Detection of Rapid Eye Movements in REM Sleep EEG Data
Soler Guevara, Andres Felipe; Drange, Ole; Furuki, Junya; Abe, Takashi; Molinas, Marta Maria Cabrera (Peer reviewed; Journal article, 2021)Rapid eye movements (REM) during sleep is a descriptor of the REM sleep stage. Parameters associated with REM sleep, such as REM sleep numbers, REM density, REM latency, and pre-REM negativity have been associated with the ... -
DYNLO: Enhancing Non-linear Regularized State Observer Brain Mapping Technique by Parameter Estimation with Extended Kalman Filter
Soler Guevara, Andres Felipe; Giraldo, Eduardo; Molinas Cabrera, Maria Marta (Journal article; Peer reviewed, 2019)The underlying activity in the brain can be estimated using methods based on discrete physiological models of the neural activity. These models involve parameters for weighting the estimated source activity of previous ... -
Low-Density EEG for Neural Activity Reconstruction Using Multivariate Empirical Mode Decomposition
Soler Guevara, Andres Felipe; Munoz, Pablo; Bueno-Lopez, Maximiliano; Giraldo, Eduardo; Molinas Cabrera, Maria Marta (Journal article; Peer reviewed, 2020)Several approaches can be used to estimate neural activity. The main differences between them concern the a priori information used and its sensitivity to high noise levels. Empirical mode decomposition (EMD) has been ... -
Low-Density EEG for Source Activity Reconstruction using Partial Brain Models
Soler Guevara, Andres Felipe; Giraldo, Eduardo; Molinas Cabrera, Maria Marta (Chapter, 2020)Brain mapping studies have shown that the source reconstruction performs with high accuracy by using high-density EEG montages, however, several EEG devices in the market provide low-density configurations andthus source ... -
Partial Brain Model For real-time classification of RGB visual stimuli: A brain mapping approach to BCI
Soler Guevara, Andres Felipe; Molinas Cabrera, Maria Marta; Giraldo, Eduardo (Chapter, 2019)Brain-computer interface (BCI) applications are characterized by real-time feature extraction and classification. Thus, brain activity reconstruction is not generally performed due to the long computation times required ... -
Searching for Unique Neural Descriptors of Primary Colours in EEG Signals: A Classification Study
Ludvigsen, Sara Lund; Buøen, Emma Horn; Soler Guevara, Andres Felipe; Molinas, Marta Maria Cabrera (Peer reviewed; Journal article, 2021)Identifying unique descriptors for primary colours in EEG signals will open the way to Brain-Computer Interface (BCI) systems that can control devices by exposure to primary colours. This study is aimed to identify such ... -
Source localization of pre-REM negativity
Drange, Ole (Master thesis, 2021)Raske øyebevegelser (REM) under søvn er en beskrivelse av REM-søvnstadiet, det er velkjent at REM-søvn spiller en viktig rolle i søvn. Derfor å finne nøyaktig hjerne aktivering før REM kan bidra til å belyse hjerneområdene ...
