MNI coordinates of brain regions that showed increased BOLD fMRI signal intensity during the sympathetic vasoconstrictor response elicited by the apneas.

The x- (right/left), y- (anterior/posterior), and z- (superior/inferior) values represent the MNI coordinates (in millimeters from the anterior commissure) for the voxel with the greatest statistical value (Z-Score) within each cluster.Definition of Abbreviations: BOLD = blood oxygen level-dependent; fMRI = functional magnetic resonance imaging; MNI = Montreal Neurological Institute.x轴（右/左）、y轴（前/后）与z轴（上/下）的数值，代表每个簇（cluster）内具有最大统计值（Z分数（Z-Score））的体素（voxel）的蒙特利尔神经研究所（Montreal Neurological Institute，MNI）坐标，该坐标以解剖学前连合为原点，单位为毫米。缩写定义如下：BOLD = 血氧水平依赖（blood oxygen level-dependent）；fMRI = 功能磁共振成像（functional magnetic resonance imaging）；MNI = 蒙特利尔神经研究所（Montreal Neurological Institute）。
