Sympathetic Nerve Activity and Baroreflex are Strongly Altered in a Context of Severe Hypertension Using the Spontaneously Hypertensive Rat Model Associated with Chronic Reduction of Nitric Oxide

Figure 1

(a) Example of raw recordings of renal sympathetic nerve activity in normotensive WKY and hypertensive SHR and SHRLN. (b) Example of RNA recording for burst analysis, thus rectified and integrated in µV/100 ms. (c) RNA analysis of burst: the maximal value/mean RSNA representing maximal amplitude (max); the minimal value/mean RSNA. Significantly different from WKY (one-way ANOVA). (d) Examples of online analysis of the RSNA-HR temporal correlation; RSNA is cumulated over 400 ms periods, triggered by systolic pressure. All examples shown are taken from our present experiments.
