Self- and other-ratings on the Big Five and a comprehensive inventory of trait affect were obtained from 74 married couples, 136 dating couples, and 279 friendship dyads. With the exception of Surprise, all scales showed significant self-other agreement in all 3 samples, thereby establishing their convergent validity. Consistent with the trait visibility(More)
CONTEXT Modafinil, a wake-promoting drug used to treat narcolepsy, is increasingly being used as a cognitive enhancer. Although initially launched as distinct from stimulants that increase extracellular dopamine by targeting dopamine transporters, recent preclinical studies suggest otherwise. OBJECTIVE To measure the acute effects of modafinil at doses(More)
Self- and partner-ratings on trait affect and the Big Five were obtained from 74 married and 136 dating couples. The relationship satisfaction of each person (the "target") was correlated with four sets of ratings: (a) target's self-rated personality, (b) target's partner-rated personality, (c) partner's self-rated personality, and (d) partner's(More)
Data reflecting affect, mood, and personality attributes of 23 normal men were compared after two weeks of placebo administration and two weeks of therapeutic serum lithium levels (mean, 0.91 mEq/liter). The study was a placebo-controlled, split-half crossover, double-blind design. Affect and mood were measured by three self-rating instruments, independent(More)
Methamphetamine is one of the most addictive and neurotoxic drugs of abuse. It produces large elevations in extracellular dopamine in the striatum through vesicular release and inhibition of the dopamine transporter. In the U.S. abuse prevalence varies by ethnicity with very low abuse among African Americans relative to Caucasians, differentiating it from(More)
The responses of 24 normal male subjects were compared after weeks of placebo administration and two weeks of lithium carbonate administration (mean serum lithium level, 0.9 mEq/liter) on a series of tasks of intellectual function, aesthetic judgement, and semantic creativity. This was a placebo-controlled, split-half crossover, double-blind design. There(More)
Images taken during the animation of the Voronoi algorithm.support a high-level organization of the time and event flow as our approach does with behavior groups based on a time and event layout. Other related systems are TBAG and UGA. TBAG is based on a functional approach. Similar to our approach, TBAG integrates constraints and graphical abstract data(More)
UNLABELLED Results from human studies with the PET radiotracer (S,S)-[(11)C]O-methyl reboxetine ([(11)C](S,S)-MRB), a ligand targeting the norepinephrine transporter (NET), are reported. Quantification methods were determined from test/retest studies, and sensitivity to pharmacological blockade was tested with different doses of atomoxetine (ATX), a drug(More)
Aromatase catalyzes the last step in estrogen biosynthesis. Brain aromatase is involved in diverse neurophysiological and behavioral functions including sexual behavior, aggression, cognition, and neuroprotection. Using positron emission tomography (PET) with the radiolabeled aromatase inhibitor [N-methyl-(11)C]vorozole, we characterized the tracer(More)
Reversible inhibitors of monoamine oxidase-A (RIMA) inhibit the breakdown of three major neurotransmitters, serotonin, norepinephrine and dopamine, offering a multi-neurotransmitter strategy for the treatment of depression. CX157 (3-fluoro-7-(2,2,2-trifluoroethoxy)phenoxathiin-10,10-dioxide) is a RIMA, which is currently in development for the treatment of(More)
