An automatic voltage adjuster was designed in order to apply an intracellular rectangular pulse of current and record the membrane potential simultaneously using a single intracellular microelectrode. The original voltage record consists of a rectangular signal signal (Va) due to the resistance of the microelectrode and a slowly rising signal (Vb) which is(More)
Dentato-rubro-pallido-luysian atrophy (DRP-LA) is a rare autosomal dominant neurodegenerative disorder. Recently the genetic abnormality has become clear. We encountered four patients with DRPLA (including a 14-year-old boy and his father) in whom the final diagnosis was made by DNA analysis. In addition to performing conventional MRI, we quantified brain(More)
