功能性近红外光学形貌(OT)用于无创测量含氧和脱氧血红蛋白的变化(Δ[HbO2], Δ[hbb]),从而研究脑血流动力学变化,这些变化是对大脑皮层特定区域功能激活的响应。然而,在分析功能性OT数据时,应该考虑到与任务相关的系统变化。在这里,我们对OT [HbO2]信号使用独立分量分析(ICA)方法,确定与任务相关的独立分量,然后将它们与全身测量(血压、心率、头皮血流量)进行比较,以评估这些分量是由全身噪声还是神经元激活引起的。因此,该分析可以提取真正的OT血流动力学神经元反应,从而区分区域激活的皮质区域和整体血流动力学变化。
Functional near-infrared optical topography (OT) is used to non-invasively measure the changes in oxygenated and deoxygenated haemoglobin (Δ[HbO2], Δ[HHb]) and hence investigate the brain haemodynamic changes, which occur in response to functional activation at specific regions of the cerebral cortex. However, when analysing functional OT data the task-related systemic changes should be taken into account. Here we used an independent component analysis (ICA) method on the OT [HbO2] signal, to determine the task related independent components and then compared them with the systemic measurements (blood pressure, heart rate, scalp blood flow) to assess whether the components are due to systemic noise or neuronal activation. This analysis can therefore extract the true OT haemodynamic neuronal response and hence discriminate between regional activated cortical areas and global haemodynamic changes.
