Abstract

Objectives: The main objective is to show current topics and future trends in the field of medical signal processing which are derived from current research concepts. Signal processing as an integrative concept within the scope of medical informatics is demonstrated.Methods: For all examples time-variant multivariate autoregressive models were used. Based on this modeling, the concept of Granger causality in terms of the time-variant Granger causality index and the time-variant partial directed coherence was realized to investigate directed information transfer between different brain regions.Results: Signal informatics encompasses several diverse domains including: processing steps, methodologies, levels and subject fields, and applications. Five trends can be recognized and in order to illustrate these trends, three analysis strategies derived from current neuroscientific studies are presented. These examples comprise high-dimensional fMRI and EEG data. In the first example, the quantification of time-variant-directed information transfer between activated brain regions on the basis of fast-fMRI data is introduced and discussed. The second example deals with the investigation of differences in word processing between dyslexic and normal reading children. Different dynamic neural networks of the directed information transfer are identified on the basis of event-related potentials. The third example shows time-variant cortical connectivity networks derived from a source model.Conclusions: These examples strongly emphasize the integrative nature of signal informatics, encompassing processing steps, methodologies, levels and subject fields, and applications.

Abstract

It has been reported as the measurements of cerebral activity by EEG and other neurophysiologic variables such as EKG and eye blinks could be extremely useful in the characterization of the "internal" state of pilots and air traffic controllers. Here, we report the results from a study aimed to use a set of validated neurometric indicators for the study of the mental workload that could occur during simulated car drive in a group of healthy subjects. In addition, it was also investigated the insurgence of sleepiness during such driving activity. Results obtained suggest that the workload index is sensitive to the mental efforts of the driver during the different drive tasks performed. In addition, results suggested as HR increases during the execution of the difficult driving tasks while instead it decreases at the insurgence of the drowsiness. The proposed workload index could be then used in a near future to assess on-line the mental state of the driver during a drive task. [ABSTRACT FROM AUTHOR]
