Context

Country: Canada
State/Province: Ontario
Period: Presumably used c. 1900- 1930s, and possibly later.
Canada: Frederick Miller, for whom this device was made, conducted research into reflexes. He employed Charles Sherrington's method of decerebration in preparing his animal subjects (mostly cats, but also dogs, guinea pigs, and other small animals), and designed his own decerebration clamp to assist with these studies. In his 1931 paper "Spinal, Bulbar and Decerebrate Reflex in the Forelimb", Miller described using " a broad microtome knife struck by a mallet" to obtain the bulbar condition necessary for his experiments. [Ref. 4]
Function: Specific- used to strike knife handle, to increase force of downward pressure exerted by blade.
Technical: Decerebratrion is the elimination of cerebral brain function in an animal by removing the cerebrum, cutting across the brain stem, or severing certain arteries in the brain stem.
Area Notes: Unknown
