• Kisaku Yoshimura, a Japanese internist, introduced the so-called Chaddock reflex in 1906, five years earlier than Chaddock's original report. Yoshimura should also be remembered in the history of clinical neurology as the person who first proposed the use of electrical stimulation to elicit the toe phenomenon.
