The effective stimulating sites were indentified by defensive cardiovascular response and other components of defence reaction evoked by 3 s trains of rectangular cathodal pulses (100Hz, 0.5ms pulse duration, 70 -150μA intensity for dPAG and 150-250μA for PF) delivered from a programmed multichannel constant current stimulator. The responses included an increase in blood pressure and heart rate, pupillodilation and an increase in the rate and depth of respiration. Currents of 1Hz, intensity of 100- 150μA for dPAG and 200-250μA for PF were used to observe the effect of the stimulation of them on RVLM neurones. The deep peroneal nerve and superfacial deep peroneal nerve were carefully separated, and put on a pair of stimulating electrode respectively, Both nerves were stimulated with constant rectangular pulses of 1Hz, 0.5ms duration and 300μA current intensity to see their effects on RVLM neurones. The baro-and chemo-receptors were activated by the intravenous injection of phenylephrine or 0.208 M NaH2PO4. The degree of convergent inputs to individual RVLM neurone was studied by the stimulation of the sites mentioned above. It was found that neurones about 61.4%(27/44) and 35.3%(6/17) received convergent inputs from three and four places respectively.

Shim current calculation When shim coils are excited by appropriate current, they can generate correcting magnetic field to compensate the imaging magnetic field unhomogeneity. Based on the indirect calculation method, we proposed a novel iterative optimization algorithm to calculate shim current. Because there is a direct proportion relationship between FID signal and magnetic field homogeneity, we use the intensity of FID signal as feedback information to the calculation. Shim current can be worked out in less than 3 minutes. This satisfied the requirement that active shimming should be performed in real time.
