continu-rate time series again revealed a statistically significant reduction in the power of the low-frequency band ous field exposure (Field by Hour interaction F Å 0.71; df Å 5,120; P Å 0.61). Again in contrast to our previous (0.0 -0.1 Hz) in subjects exposed to 200 mG intermittent magnetic fields

. This means that blood itself serves as a contrast agent, making the MRI signal sensitive to brain activation. Changes in activation can therefore be inferred from the voxels' changes in brightness at each time point. The fMRI procedure is thought to be quite safe, uses the subject's blood itself

This report focuses on the evidence about the health.consequences of smoking for women, and is intended to serve.the public health and medical communities as 'a unified source of existing scientific research. The major issues about tobacco use and women's health are examined, including trends in consumption, biomedical evidence, and determinants of smoking ititiation, maintenance, and cessation. The biomedical aspects ofsmoking are presented in terms of mortality, morbiplity, cardiovasculaidiseases, cancer, pregnancy and infant,health,, Teptic ulcer disease, drug reactions and, interactions, food constituents, and responses to,diagnostic tests. The psychosocial and behavioraj. aspects, of smoking in women are discussed, along with the docffiented increases in- the risk of contracting lung cancer, heart,disease, or lung disease. The harmful effects of pregnant mothers smoking behaviors, are also docudented. Adhitionally, recent data are enumerated to indicate a trend of,decreasing tobacco usage among women in response to the warnings of the gavernMent, voluntary agencie, and physicrins.

facial emotion for right-handed individuals in relation to three measures of handedness: degree of handedness, writing posture, and familial left-handedness. The motor cortex is perhaps the part of the brain where effects of handedness and hand usage are most apparent (see A functional MRI (fMRI

mcmxciv This thesis deals with combinatorics in connection with Coxeter groups, finitely generated but not necessarily finite. The representation theory of groups as nonsingular matrices over a field is of immense theoretical importance, but also basic for computational group theory, where

the expectations of the experimenter and informed a subgroup of participants that performance on the task would be rewarded (after Ryan & Deci, 2000). Using this paradigm and functional magnetic resonance imaging (fMRI), we report a network of brain regions in which diminished task-related activity predicted

to the primary and/or secondary auditory cortex depending on factors known to influence auditory streaming The possibility that cortical areas beyond the auditory cortex contribute to the perception of auditory streams is suggested by fMRI data. In particular, one study found significantly greater activation
