Abstract
IN the rat a period of poikilothermy exists for approximately the first seventeen days of life1–2. In this phase of the development action potentials and nerve conduction rate decrease with the lowering of the environmental temperature3. Temperature may change, therefore, the ability of the new-born rat to learn the conditioned leg withdrawal to a vibrotactile stimulus.
