Schematic summary of effects of pHi and/or Vmem on MT (cf. Figure 9). Alkalisation (together with slight hyperpolarisation or no clear effect on Vmem) caused by furosemide, glibenclamide or 9-anthroic acid led to diffuse MT in all FC and to loss of their longitudinal alignment. This was accompanied by enhanced angles of pHi-gradients and reduced angles of Vmem-gradients (shown on the right, cf. Figure 2). Slight alkalisation together with strong hyperpolarisation as well as enhanced angles of pHi-gradients and reduced angles of Vmem-gradients (verapamil; shown on the right, cf. Figure 2) maintained the longitudinal MT-organisation. This was complemented by thickening of the MT-bundles
