The present study examines the behavioral and psychophysiological effects of phenytoin (PHT) in individuals who display impulsive-aggressive outbursts. In a double-blind placebo-controlled crossover design, individuals meeting previously established criteria for impulsive aggression were administered PHT and placebo during separate 6-week conditions. The(More)
This study demonstrates the reliability of 3 Clock Drawing Test (CDT) scoring systems when applied to the protocols of stroke patients. The sample included 20 randomly selected sets of both freehand and predrawn circle versions ofthe CDT completed by patients undergoing comprehensive stroke rehabilitation. The protocols were scored independently by 2 raters(More)
This study compared the behavioral effects of 3 anticonvulsants in impulsive aggressive men. In a double-blind, placebo-controlled, parallel groups design, participants were randomly assigned to 1 of 4 6-week treatments: phenytoin (n = 7), carbamazepine (n = 7), valproate (n = 7), or placebo (n = 8). The efficacy measure was the average aggression score, a(More)
The present study attempted to replicate the findings of previous factor analytic studies of the Wisconsin Card Sorting Test (WCST) in a homogeneous sample of patients suffering recent cerebrovascular accidents and being treated in a comprehensive inpatient physical rehabilitation program. In addition this study examined the relationship of the WCST to(More)
BACKGROUND St. Louis encephalitis (SLE) is a relatively common cause of neurological illness, yet little is known about its cognitive and psychosocial consequences. PURPOSE To describe the cognitive, emotional, psychophysiological, and psychosocial consequences of SLE infection. METHOD A comprehensive neuropsychological and psychophysiological(More)
The Hooper Visual Organization Test (HVOT; Hooper, 1958) is a commonly used measure of visual perceptual function. However, serious questions have recently been raised about its construct validity (i.e., the role of object naming). This study further examined the HVOT's construct validity and began exploring its contribution to outcome prediction in stroke(More)
In this work we propose a high-speed hybrid optical-time-division-multiplexing (OTDM) and wavelength-division-multiplexing (WDM) system that seamlessly generates high bit-rate data (>;200Gbit/s) from a low speed (5Gbit/s) quantum-dot mode locked laser pulse train. The high-speed output data can be generated using electro-optical micro-ring modulators(More)
