Polygraph

 

a multichanneled oscillograph for simultaneously recording readings of several physiological functions, such as respiration, blood pressure, brain and muscle bioelectricity, and motor reactions. The most common type is the general-purpose polygraph, a multichanneled oscillograph that records with ink various bioelectric and nonelectric processes by means of appropriate biological sensors and adapters. The polygraph is used in physiological experiments to investigate interacting and interdependent bodily functions; it is also used in clinical diagnosis.
