ACOUSTIC INTERFERENCE ON ATTENTION IN HIV PATIENTS

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。目的：评价血清阴性健康志愿者功能磁共振成像中噪声干扰的性别差异。为了确定功能磁共振声学噪声对艾滋病毒阳性男性功能磁共振成像研究的影响(由于艾滋病毒患者在功能磁共振成像上的受试者间变异性较大，在这项初步研究中，我们将首先评估男性的影响)。目的：确定健康志愿者和HIV患者脑部代谢产物浓度(MRS)与功能磁共振成像(FMRI)中噪声相关变化之间的关系。

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.
