Model Ⅰ: 26 rabbits, ether anesthesia, automatic breathing. The neck is separated from both vertebral and external carotid arteries and the sinus nerves are removed, ligating the arterioles. Multi-channel electromagnetic flowmeter transducer placed in the carotid artery near the internal carotid artery, measuring both sides of the internal carotid artery blood flow (ICABFV, 86.22 ± 19.17ml / min) after the left carotid artery ligation and compression of the right carotid artery, The right control ICABFV was at 16.07 ± 5.54 ml / min.
