Fig. 11: Conceptual model of the trunk stabilization system and effects of left-right asymmetry in activity of CaMKIIa-RNs.
From: Role of CaMKIIa reticular neurons of caudal medulla in control of posture
A–D Presumed effects of the two antagonistic postural limb reflexes (PLRs) in the unrestrained standing mouse in control (A and B) and during activation of right CaMKIIa-RNs (C and D). A and C: the abscissa shows a deviation of the dorso-ventral body axis from the vertical (lateral sway); the ordinate shows the values of the right and left (L) PLRs (PLR-R and PLR-L, solid and dashed lines, respectively). Black and white arrows indicate the motor effect (lateral sway) caused by PLR-R and PLR-L, respectively. B, D The stabilized orientation (1), effect of the lateral push (2), and the restored orientation (3). E The shift of the set-point of the postural control system caused by the left-right asymmetry in activity of CaMKIIa-RNs allows to the animal stabilize the dorsal side-up orientation on the laterally inclined surface. (See DISCUSSION for details).
