本研究探讨了静息状态下前扣带回和后扣带回γ-氨基丁酸(GABA)和谷氨酸(Glu)含量与脑血流量(CBF)的关系。从10名健康对照者中获得AC和PC的1H磁共振波谱测量值和伪连续动脉自旋标记数据。AC的GABA水平与整体(全脑)CBF呈强负相关(r =-0.91,p=0.0015)。GABA水平从PC和谷氨酸水平从这两个地区没有显着相关性与CBF。我们假设GABA介导的抑制AC激活蓝斑-去甲肾上腺素通路可能会影响全球CBF。
This study examined the relationship of γ-aminobutyric acid (GABA) and glutamate levels from the anterior and posterior cingulates (AC and PC) with cerebral blood flow (CBF) at rest. 1H magnetic resonance spectroscopy measurements in the AC and PC and pseudo-continuous arterial spin labeling data were acquired from 10 healthy controls. GABA levels from the AC were strongly inversely correlated with global (whole-brain) CBF (r =−0.91, p=0.0015). GABA levels from the PC and glutamate levels from both regions were not significantly correlated with CBF. We hypothesize that GABA-mediated inhibition of AC activation of the locus coeruleus-norepinephrine pathway may influence global CBF.
