Epidural pressure measurement in the rat.
An original device for the epidural pressure measurement in the rat is presented. The reliability of epidural pressure as an index of intracranial pressure is discussed and several possible causes of error are examined. The device has been tested under conditions both of transient and prolonged cerebral blood volume increase, obtained by venous outflow obstruction.
