EEG-Grundaktivität und Intelligenz
Um zu untersuchen, ob ein Zusammenhang zwischen EEG-Merkmalen und Leistung im Intelligenztest besteht, wurde retrospektiv bei 69 Kindern im Alter 10+-1Jahr, die in den Jahren 1996 und 1997 am Sozialpädiatrischen Zentrum Inn-Salzach in Altötting untersucht wurden, die Intelligenztestung mit dem …

EEG theta oscillations during sleep deprivation
… characterize the electroencephalogram (EEG) during distinct cognitive and vigilant states. Theta oscillations (4-8 Hz) are unusual because they have been found in the near-opposite conditions of sleepiness and alert cognitive control. Most neuroscience research fo-cuses exclusively on …

Pinky : interactively analyzing large EEG datasets
… analyzing large electroencephalogram (EEG) datasets. Trained experts, known as encephalographers, analyze EEG data to determine if a patient has experienced an epileptic seizure. Since EEG analysis is time intensive for large datasets, there is a growing corpus of unanalyzed EEG data. …

EEG signal processing in brain-computer interface
… activities is produced. Electroencephalography (EEG) is one way of measuring and recording of the electrical signals produced by these electrical activities via some sensor arrays across the scalp. Although there is plentiful research in using EEG technology in the fields of neuroscience and …

Assessment of Mental Workload by EEG+fNIRS
… human MWL. We have used electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) as the imaging modalities with seventeen healthy subjects performing the letter n-back task, a standard experimental paradigm related to working memory. For simultaneous EEG+fNIRS data …

EEG-Kohärenzanalysen zu kognitiven Prozessen im Arbeitsgedächtnis
… und als psychophysiologisches Verfahren das EEG ausgewählt, das kohärenzanalytisch unter Nutzung eines neuen, zeitlich hochauflösenden kontinuierlichen Schätzverfahrens der Kohärenzfunktion (Schack, 1997) ausgewertet wurde. Die Ergebnisse offenbaren zum einen deutliche topographische …

EEG theta power during Necker cube reversals
… undergraduate psychology students had monopolar EEG recorded bilaterally from frontal and parietal electrode sites. The subjects viewed computer presentations of the Necker cube under two different experimental conditions: a passive condition in which they were not instructed to influence …

EEG-based Brain Computer Interface with Deep Learning
Electroencephalogram (EEG)-based Brain Computer Interfaces (BCI) are very important and have been widely used in multiple application domains, ranging from human-computer interaction to medical and biomedical applications. To overcome the challenge of EEG representation learning, we propose a Long …

An EEG Study on Loneliness and Recognition Memory
… responses, completed an associative memory task. EEG was used to assess recognition memory effects. Results showed no significant difference in both behavioral and ERP recognition memory effects between lonely groups, showing that lonelier individuals had no specific recollection-based recognition …

Optimising image feature zero-shot-learning with EEG
… a discriminative feature extraction process for EEG brain data and establish a baseline evaluation of exemplar and category-level decoding. Once competitive decoding rates are achieved, we extend this framework to address our zero-shot restriction by making use of computer vision, linguistic, and …

Orienting of willed temporal attention: an EEG study
… by looking at both behavioural data as well as EEG. To explore that question the temporal cueing task was used in which a cue instructed a participant to anticipate either short (800 ms) or a long (2000 ms) interval between cue and target presentation times. Alternatively, a cue instructed a …

An information theoretic approach to EEG-fMRI integration
… of signals from electro-encephalography (EEG) and functional magnetic resonance imaging (fMRI), acquired simultaneously from the same observer, holds great potential for the elucidation of the neurobiological underpinnings of human brain function. However, the most appropriate way in which …
