Constraints on the deformation of the vibrissa within the follicle

Increasing blood pressure causes decreased whisker displacement, but higher internal forces at the RS level.
(A) The change of r(x) as the hydrostatic pressure in the RS is simulated to increase by increasing k3. From orange to blue, the value of k3 increases logarithmically from 105 to106N/m. With higher blood pressure, r(x) in the RS region decreases. (B) The change in the relative displacement and the force at the RS level as the blood pressure increase. Left y-axis, solid line: relative displacement at the RS level, r(x)|x = 0.6mm. Right y-axis, dashed line: the relative change of the internal force at the RS level from base state (k3 = 105N/m). The force is given by k3∙r(x)|x = 0.6mm. As the blood pressure increases, the relative displacement at the RS level drops, whereas the force increases.
