METHODS Auditory and visual sustained attention were investigated in 265 low-income, predominantly African-American, adolescents (mean age, 15.12 years; SD,(More)
Real-Time Services (RTS) will rely on distributed capabilities to enable end-to-end management of IP based voice and video services across multiple domains. Policy Based Enterprise Management (PBEM) will be a key RTS enabler by coordinating and automating management processes among domains. This will facilitate effective distributed management of RTS(More)
Phenylketonuria provides a human model for the study of the effect of phenylalanine on brain function. Although irreversible mental retardation is preventable through newborn diagnosis and dietary phenylalanine restriction, controversy exists regarding the effects of increased concentrations of phenylalanine in older patients.

Five papers by Peniston and colleagues, which constitute the basic literature for alpha-theta EEG biofeedback treatment for alcoholism and posttraumatic stress disorder, are reviewed.

Posner's covert orienting of attention paradigm has been used in many studies in the cognitive neuroscience literature to study attention. We found 9 studies in which it was used to study attention deficit hyperactivity disorder, but findings were not consistent. We present a tutorial about the paradigm's methodology and then review the studies. It emerges(More)
Prior work has found evidence of hyperpriming in schizophrenics, which has been related to a persistence of associational activation in thought disorder. We extended this work by administering a lateralized version of the lexical decision task to 10 thought-disordered schizophrenics (TD), 10 non-thought-disordered schizophrenics (NTD), and 11 control(More)
