Filter by:The purpose of this study is to confirm that 2-HOBA crosses the blood brain barrier and to compare blood and cerebrospinal fluid levels of 2-HOBA after a single oral dose.
Financial decisions are made during pre-retirement age that can influence financial well-being for the rest of an individual's life. This proposal aims to construct a more comprehensive model of the specific psychological and neural mechanisms that support financial decisions in young adulthood and late middle age. In Part 1 of this study (covered in Institutional Review Board (IRB) # 141812), middle-age and young adults complete basic cognitive, motivational, and decision making tasks and are studied with functional magnetic resonance imaging (fMRI) to determine the relation between neural circuit activation and individual and age-related differences in decision making. In part II of the study, aspects of dopamine functioning are studied using positron emission tomography (PET) scanning to determine whether individual differences in dopamine functions are related to the decision-making and fMRI measures collected in Part 1 of the study. Dopamine measures include baseline D2 receptor availability, amphetamine induced dopamine release and dopamine transporter (DAT) levels, which provides a more comprehensive evaluation of dopamine functions than in prior studies linking individual differences in dopamine to behavioral, cognitive or decision-making traits.
Pilot study of a soft, flexible pressure and temperature sensor
The purpose of this study is to investigate whether there are differences in postprandial cardiometabolic metabolic indices following interesterified fats used commercially versus application appropriate non- interesterifed alternative fat.
Purpose: To examine the safety of the use of two wheelchair cushions for healthy individuals with intact sensation and individuals post stroke and spinal cord injury with impaired sensation. The new Ease Alternating Pressure wheelchair cushion will be compared to a static air cushion to examine interface pressure and skin responses in the areas of the buttock and posterior thighs when subjects sit without moving (static condition) and during upper extremity reaching activities (active condition). In addition, comfort, ease of transfer, and postural stability will be monitored while sitting on both cushions under both static and active conditions.
This is a randomized, double-blind, parallel-group, placebo-controlled, single-dose escalation Phase I study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of denosumab injection administered subcutaneously to healthy adults in China
The primary goal of the present study is to test whether neural activity in brain regions associated with processing threat and social stimuli may underlie paranoid thinking.
This study investigates whether the way in which individuals process social stimuli can be altered, and specifically, whether feelings of paranoia and suspiciousness can be reduced by stimulating the brain's regulatory regions via transcranial Direct Current Stimulation (tDCS).
The overall objective of this study is to investigate the neural correlate in retrieval memory task. The aim of the study is to understand the undergoing changes in late positive ERP component during retrieval memory task when stimulating the posterior cingulate cortex (PCC) with High Definition Transcranial Direct Current Stimulation (HD-tDCS).
The purpose of this study is to investigate whether learning can be accelerated and associative memory performance improved in healthy subjects by applying transcranial Direct Current Stimulation (tDCS) during a Face Name memory task.
