Q. What is the basic principle of analgesiometer?

The hot plate test is regarded to be a supraspinally organised reaction since it includes higher brain function. In this experiment a rat or mouse is placed inside a cylindrical chamber that has no closed-off ends. The bottom of the chamber is made up of a metallic plate that is heated by a thermode or a liquid that is boiling. Two behavioural components namely paw licking and leaping may be assessed in terms of their response times when they are exposed to a plate that is maintained at a constant temperature. Both of these reactions are thought to be integrated above the spinal column. The thermal stimulation approach that is employed is called radiant heat. The administration of a stimulus in this case one that is generated by a nichrome wire is the driving force behind the analgesiometer's operation.
