That balancing act is called autoregulation and keeps your blood pressure relatively normal.
This dynamic regulation of cerebrovascular resistance maintains a constant CBF in the CPP range between 50 mm Hg to 150 mm Hg and is called autoregulation (Fig. 3) [59,60].
In this study, investigators are using a novel optical imaging technique to investigate cerebrovascular autoregulation in preterm infants.
But excess blood glucose negates and destroys this autoregulation system, thus taxing your arteries more heavily.
Failure of cerebral autoregulation as a cause of brain dysfunction in the elderly.
Positive autoregulation with no coding variation generated about the same proportion of overdominance for the sign motifs [0 0 +], [0 + +]
Negative and positive feedback are mathematically well-defined concepts when used in connection with ordinary differential equation systems, and the terms do not acquire different meanings in different contexts In Appendix S1 we show analytically for a generalization of eqns. (4) that negative autoregulation generates a negative allele interaction sign and that positive autoregulation generates a positive allele interaction sign.
