There has been much interest recently in the concept of using information from the motor cortex region of the brain, recorded using non-invasive scalp electrodes, to construct a crude interface with a computer. It is known that movements of the limbs, for example, are accompanied by desynchronisations and synchronisations within the scalp-recorded electroencephalogram (EEG). These event-related desynchronisations and synchronisations (ERD and ERS), however, appear to be present when volition to move a limb occurs, even when actual movement of the limb does not in fact take place. The determination and classification of the ERD/S offers many exciting possibilities for the control of peripheral devices via computer analysis. To date most effort has concentrated on the analysis of the changes in absolute frequency content of signals recorded from the motor cortex. The authors present results which tackle the issues of both the interpretation of changes in signals with time and across channels with simple methods which monitor the temporal and spatial 'complexity' of the data. Results are shown on synthetic and real data sets.

A vital part of restructuring in hospitals is a continuing effort to find ways to meet the growing demands of caregivers for efficient ways to enter and retrieve patient information. The process of effectively meeting these demands was coordinated through the leadership and efforts of the chief nurse executive and the information manager for nursing at New York Veterans Affairs Medical Center. These efforts resulted in timely support for restructuring, improvement in the development of competency skills among nursing staff, and increase in the use of electronic methods for documentation of patient care. Discussion of the changes implemented include approaches and content of training for computer skills development, a position description for an expanded role of a nurse in the field of informatics, and the facility's structure that fits a patient-centered care model.
