BACKGROUND Severe traumatic stressors such as war, rape, or life-threatening accidents can result in a debilitating psychopathological development conceptualised as Posttraumatic Stress Disorder (PTSD). Pathological memory formation during an alarm response may set the precondition for PTSD to occur. If true, a lack of memory formation by extended(More)
BACKGROUND Patients with a psychogenic paresis have difficulties performing voluntary movements. Typically, diagnostic interventions are normal. We tested whether patients with a psychogenic lower limb paresis exhibit abnormal motor excitability during motor imagery or movement observation. METHODS Transcranial magnetic stimulation (TMS) with single and(More)
The need for more performance from computer equipment in data centers has driven the power consumed to levels that are straining thermal management in the centers. When the computer industry switched from bipolar to CMOS transistors in the early 1990s, low-power CMOS technology was expected to resolve all problems associated with power and heat. However,(More)
The neural mechanisms underlying conversion disorders such as hysterical blindness are at present unknown. Typically, patients are diagnosed through exclusion of neurological disease and the absence of pathologic neurophysiological diagnostic findings. Here, we investigate the neural basis of this disorder by combining electrophysiological (event-related(More)
BACKGROUND Patients with motor conversion disorders present an inability to execute movements voluntarily, although central and peripheral motor pathways are normal. We speculated that this phenomenon could be due to an abnormal loss of excitatory drive on central motor areas. METHODS The effect of motor imagery on motor excitability was tested in a group(More)
OBJECTIVE Surface electromyography was used to identify muscles active in isometric elbow extension in spinal cord-injured (SCI) patients. DESIGN Tetraplegic subjects participated in this cohort study aimed at identifying some of the muscles that are active during isometric elbow extension. SETTING Regional Spinal Cord Injury (SCI) Center. PATIENTS(More)
