Paw-withdrawal threshold

SpletThe 50% withdrawal threshold is determined by counting 6 critical responses when the response threshold is first crossed (positive to negative or negative to positive) followed by 4 additional stimuli applications (up or down). The number of actual responses collected using this paradigm can vary from a minimum of 4 to a maximum of 9. SpletThe withdrawal reflex that occurs before vocalization is prevented by smoothly holding the rat’s hindpaw in position under the pusher until vocalization. The two paws are tested consecutively in each rat. The sequence of sides is alternated between the animals to prevent “order” effects.
