Workload-Aware Systems and Interfaces for Cognitive Augmentation [article]

Thomas Kosch
2020 arXiv   pre-print
Together with the collected data sets, this thesis paves the way for methodical and technical tools that integrate workload-awareness as a factor for context-aware systems.  ...  Subsequently, we investigate suitable feedback modalities in a user-centric design process which are desirable for cognitive assistance.  ...  The desire to investigate the impact of VR scenes on the brain is high but becomes complicated because of the linearly increasing output of an EEG over time.  ...

Neural correlates of consciousness

Geraint Rees
2013 Annals of the New York Academy of Sciences  
Jon Driver's scientific work was characterized by an innovative combination of new methods for studying mental processes in the human brain in an integrative manner.  ...  In our collaborative work, he applied this approach to the study of attention and awareness, and their relationship to neural activity in the human brain.  ...  But although neglect apparently involves a dramatic loss of awareness of sensory events occurring on the affected side, paradoxically such a loss can occur even though the primary sensory pathways for  ...

The Application of Electro- and Magneto-Encephalography in Tinnitus Research – Methods and Interpretations

Peyman Adjamian
2014 Frontiers in Neurology  
In recent years, there has been a significant increase in the use of electroencephalography (EEG) and magnetoencephalography (MEG) to investigate changes in oscillatory brain activity associated with tinnitus  ...  Current view of the underlying mechanism of tinnitus is that it results from changes in brain activity in various structures of the brain as a consequence of sensory deprivation.  ...  DETECTION OF DEEP SUB-CORTICAL SOURCES WITH M/EEG Due to the deep position of structures involved in top-down processing within the brain, the question for M/EEG is one of their sensitivity to detecting  ...
