Correlative analysis of SUV [18F]GE180 uptake in the ipsilesional vestibular nucleus (VN) and behavioral scores. (A) [18F]GE180 uptake on day 7 post-unilateral labyrinthectomy (UL) correlated negatively with the daily changes in postural asymmetry scores of UL rats (N = 10). (B) The negative correlation between translocator protein (TSPO) activation in the ipsilesional VN and the degree of compensation was still present for [18F]GE180 uptake on day 15 post-UL (N = 9 rats). (C) Exemplary autoradiography at the level of the VN and facial nucleus (FN) (including anatomical verification by histology) from a rat with very fast vestibular compensation (VC) until death on day 7 (green, upper image, high [18F]GE180 uptake) and another slice from a rat with very slow VC until death on the same day (red, lower image, low [18F]GE180 uptake).
