OBJECTIVES To study working memory function in untreated major depression using a digit probe identification and matching task. METHODS We compared behavioural performance and event-related potentials during processing of the Sternberg working memory task in 14 depressed patients and 14 healthy matched control subjects. RESULTS Patients made more… (More)
Any relationship between measures of cognitive function and brain electrical activity would be of considerable importance in the objective assessment of patients suspected of intellectual impairment. In healthy subjects, we have found a strong correlation between the event-related potentials evoked by a digit probe identification task and scores on… (More)
The inter-subject wave form variability of auditory event-related potentials (ERPs) evoked by digit probe identification in a memory-scanning task (Sternberg paradigm) and the effects of reaction time (RT) and task difficulty were studied in 26 healthy subjects. The response wave forms were compared with the performance of psychological tests of… (More)
INTRODUCTION The Life Support for Trauma and Transport (LSTAT trade mark ) is a self-contained, stretcher-based miniature intensive care unit designed by the United States Army to provide care for critically injured patients during transport and in remote settings where resources are limited. The LSTAT contains conventional medical equipment that has been… (More)
Based on earlier experiments with cats, we have developed two new hearing tests to evaluate the ability of patients with temporal lobe damage to discriminate tones of short temporal duration. Earlier published studies suggested that patients exhibit notably increased thresholds for detecting tone pulses shorter than 200 ms in length when the signals are… (More)
