  • Hotchkiss K, Harvey M,WProblem: Electrical activity in hair cells and neurons of the inner ear is necessary for the transduction and modulation of stimuli impinging on the cochlea and vestibular endorgans of the inner ear. The underlying bases of this activity are pore-forming proteins in the membrane of excitable cells that allow the influx and efflux of various ions including Na+, Ca2+, and K+, among others. These channels are critical to both electrical activity and the development of excitable cells since they may initiate long-term signals important in the maintenance and survival of these cells. We investigate the expression of Shaker and Shal potassium ion channel proteins in the vestibular endorgans of mammalian species including mouse and human.Sokolowski BHA Ion channels in the vestibular tissue of mouse and human.
