Figure 4.

Modeling study illustrating the consequences, in regard to the regulation of glomerular capillary pressure, of two differing myogenic mechanisms, one in which the level of tone is dependent on mean BP (left), the second in which tone is dependent on the systolic BP (right). Note that a similar regulation of P_GC is seen when mean and systolic pressure change in concert (A). However, isolated transients in systolic pressure are transmitted to the glomerulus when mean pressure sets myogenic tone, but not when tone is set by the systolic signal (B).
