The neurovascular coupling ensures that cerebral activity is matched by the relevant blood flow. The control of the blood flow is mediated by capillaries and by the precapillary aterioles. It is the tone of the mural cells, which include pericytes, smooth muscle cells and cells with intermediate phenotypes between pericytes and smooth muscle cells, that determine the the diameter of the blood vessels and consequently the flow. Here we discuss the structure of these blood vessels and the excitationcontraction coupling of the mural cells.

脑毛细血管周细胞和神经血管耦合

神经血管耦合确保大脑活动与相关血流相匹配。血流的控制是由毛细血管和毛细血管前小动脉介导的。是壁细胞（包括周细胞、平滑肌细胞和具有介于周细胞和平滑肌细胞之间的中间表型的细胞）的音调决定了血管的直径，从而决定了血流。在这里，我们讨论这些血管的结构和壁细胞的兴奋收缩耦合。
