In the monkey dorsal raphe, we reported that 1-month (mo) of estrogen replacement, with or without progesterone supplementation for 14 days, significantly increased tryptophan hydroxylase-1 (TPH-1) mRNA; decreased serotonin reuptake transporter (SERT) mRNA and decreased monoamine oxidase (MAO)-A mRNA, but had no effect on MAO-B mRNA. Here, we questioned(More)
OBJECTIVE Nuclear factor kappa B (NFkappaB) is a transcription factor that activates gene expression in response to proinflammatory cytokines, and elevated cytokines are associated with depression, which has a serotonergic component. We questioned (1) whether serotonin neurons contain NFkappaB, (2) whether NFkappaB detection with immunocytochemistry is(More)
BACKGROUND Persons with vision loss may have limited ability to experience visual arts and difficulty navigating unfamiliar environments. The Center for Advanced Visual Studies at Massachusetts Institute of Technology developed a Retinal Imaging Machine Vision System (RIMVS) "seeing machine" to project "word-images" onto the retina and permit navigation(More)
Adolescents' video gaming is increasing at a rapid rate. Yet, little is known about what factors contribute toward more hours of gaming per week, as well as what factors may limit or protect adolescents from excessive gaming. The aim of the present study was to examine associations between adolescents' accessibility to video gaming devices, the locations(More)
This study used fMRI to investigate the neural substrates of moral cognition in health resource allocation decision problems. In particular, it investigated the cognitive and emotional processes that underpin utilitarian approaches to health care rationing such as Quality Adjusted Life Years (QALYs). Participants viewed hypothetical medical and nonmedical(More)
