SummaryOur material on medical legal investigations backs up the theory that the time of amnesia as part of the commotio cerebri seems to be prolonged under the influence of alcohol, and that...

AbstractIt has been known since the publication of work by Berger (1933), Jasper and Andrews (1938) and Jasper and Penfield (1949) that in conscious human subjects sensory perception or motor behavior...
View ArticleEvent-Related Desynchronization (ERD) Correlated with Cognitive Activity
AbstractOne characteristic feature of the human brain is its ability to generate rhythmic activity within the 7–13 Hz (alpha) and 15–20 Hz (beta) frequency band. These rhythmic activities can be found...

SummaryMultichannel EEG recordings were performed during a visual-verbal judgement task with a verbal response using an event-related paradigm. EEG trials of 7 sec were first digitally band pass...
View ArticleAlpha frequency, cognitive load and memory performance
SummaryEEG-signals were recorded from subjects as they performed a modified version of Schneider's and Shiffrin's memory search paradigm. The hypothesis was tested whether individual (centre of...

Abstract. Measures of event-related band power such as event-related desynchronization (ERD) are conventionally analyzed within fixed frequency bands, although it is known that EEG frequency varies as...
View ArticleRelevance of EEG alpha and theta oscillations during task switching
AbstractIn a task switching design, we investigated the question whether long-range theta coupling primarily reflects top–down control processes. Switch and stay trials did not differ with respect to...

The functional significance of sleep spindles for overnight memory consolidation and general learning aptitude as well as the effect of four 10-minute sessions of spindle frequency (11.6–16 Hz, sigma)...
View ArticleInvolvement of sleep spindles in overnight declarative memory stabilization
AbstractObjectiveNumerous studies point to the involvement of sleep spindles and slow waves in memory processes, particularly in hippocampus-dependent declarative memory. We have shown previously that...
