Faces evoke spatially differentiated patterns of BOLD activation and deactivation.
Using fMRI techniques sensitive to blood oxygen-level dependent (BOLD) contrast, we measured brain activity in participants (n=8) as they viewed images of faces presented periodically within a continuously changing montage ...
Dominance, politics, and physiology: voters' testosterone changes on the night of the 2008 United States presidential election.

Enhanced rewarding properties of morphine, but not cocaine, in beta(arrestin)-2 knock-out mice.
(J Neurosci, 2003-11-12)
The reinforcing and psychomotor effects of morphine involve opiate stimulation of the dopaminergic system via activation of mu-opioid receptors (muOR). Both mu-opioid and dopamine receptors are members of the G-protein-coupled ...
Functional parcellation of attentional control regions of the brain.
(J Cogn Neurosci, 2004-01)
Recently, a number of investigators have examined the neural loci of psychological processes enabling the control of visual spatial attention using cued-attention paradigms in combination with event-related functional magnetic ...
Common genetic variation and the control of HIV-1 in humans.
(PLoS Genet, 2009-12)
To extend the understanding of host genetic determinants of HIV-1 control, we performed a genome-wide association study in a cohort of 2,554 infected Caucasian subjects. The study was powered to detect common genetic variants ...
Construct and differential item functioning in the assessment of prescription opioid use disorders among American adolescents.
(Journal of the American Academy of Child and Adolescent Psychiatry, 2009-05)
