In the present study, we used positron emission tomography to investigate changes in regional
cerebral blood flow (rCBF) during a general anesthetic infusion set to produce a gradual …

Background The Patient State Index (PSI) uses derived quantitative electroencephalogram
features in a multivariate algorithm that varies as a function of hypnotic state. Data are …

Background It is postulated that alteration of central cholinergic transmission plays an
important role in the mechanism by which anesthetics produce unconsciousness. The authors …

Three studies were performed to assess the effects of a high-fat diet and exercise-induced
changes in fat oxidation on energy intake in humans. In the first study the short-term effect of a …

Background The extent to which complex auditory stimuli are processed and differentiated
during general anesthesia is unknown. The authors used blood oxygenation level-dependent …

IMPLICATIONS: Auditory steady-state responses to stimuli presented at rates near 40 Hz
can be used to monitor anesthesia. These responses can be quickly and reliably recorded …

The auditory middle latency response (AMLR) and the 40-Hz auditory steady-state response
(40-Hz ASSR) are evoked potentials which possibly arise from the same generators in the …

Background As obesity is rapidly becoming a major medical and public health problem, the
aim of our study was to determine: 1) if obesity in Caucasian adolescents at 5 different …

OBJECTIVE To review the evidence on prevention and management of childhood obesity and

Background Anatomic and physiologic data show that multiple regions of the forebrain are
activated by pain. However, the effect of anesthetic level on nociceptive input to these regions …
