PET IMAGING OF BRAIN METABOLIC RESPONSES TO LOW FIELD MAGNETIC STIMULATION

这个子项目是许多利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 我们将在3种条件下评估24名正常对照受试者的脑葡萄糖代谢活动：基线（无EPI）;在扫描仪等中心点处有EPI读出梯度脉冲;在扫描仪等中心点外有EPI读出梯度脉冲。 我们假设，额叶（即前扣带回）代谢将显着增加等中心条件相比，偏离等中心/基线条件。

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. We will evaluate brain glucose metabolic activity in 24 normal control subjects under 3 conditions: at baseline (without EPI); at the scanner isocenter with EPI readout gradient pulses; and off the scanner isocenter with EPI readout gradient pulses. We hypothesize that frontal (i.e. anterior cingulate gyrus) metabolism will be significantly increased for the isocenter condition when compared to the off-isocenter/baseline conditions.
