ACOUSTIC INTERFERENCE ON ATTENTION IN HIV PATIENTS

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。评价血清阴性健康志愿者fMRI过程中声噪声干扰的性别差异。为了确定fMRI-声学噪声对HIV阳性男性fMRI研究的影响（由于HIV患者在fMRI上的受试者间差异较大，因此在本初步研究中，我们将首先评估男性的影响）。确定健康志愿者和HIV患者fMRI中与噪声相关的变化与大脑代谢物浓度（在MRS上）之间的关系。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. To evaluate sex-differences in acoustic noise interference during fMRI in seronegative healthy volunteers. To determine the effect of fMRI-acoustic noise on fMRI studies in HIV-positive men (due to the larger inter-subject variability in HIV patients on fMRI, for this preliminary study we will first evaluate the effects in men). To determine the relationship between acoustic noise-related changes in fMRI and metabolite concentrations (on MRS) in the brain for healthy volunteers and HIV patients.
