• central nervous system nodes of Ranvier remain intact after tamoxifen treatment
• Purkinje cells from tamoxifen-treated mice exhibit axon initial segment disintegration compared with control mice
• after 16 weeks, Purkinje cells from tamoxifen-treated mice lack pinceau synapses or exhibit reduced pinceau synapse size compared with control mice
• Purkinje cells tamoxifen-treated mice require a greater current to drive spike firing compared with control mice
• wave-form of action potential exhibit reduced maximum rate of rise and peak amplitude and increased half-width and delay until peak of the afterhyperpolarization potential compared to in control cells
• Purkinje cells of tamoxifen-treated mice fail to maintain spontaneous action potential firing and instead maintain a modal resting potential compared with control cells

behavior/neurological
• at 6 weeks, tamoxifen-treated mice exhibit impaired performance and balance on a rotarod compared with wild-type mice
• at 6 weeks, tamoxifen-treated mice exhibit impaired performance and balance on a rotarod compared with wild-type mice
• in tamoxifen-treated mice at 6 weeks
