- CNS), most likely in a part of the CNS called the pyramidal tract. Asymmetry of the plantar response — when it is present on one side but not the other — is abnormal. It is a sign not merely of trouble but helps to lateralize that trouble (tell which side of the CNS is involved). The plantar response is known by a number of other names including the toe or big toe sign or phenomenon and the Babinski reflex, phenomenon or sign (from the late French neurologist who described it). It is, incidentally, quite common but entirely wrong to say that the plantar response is positive or negative; it is present or absent.
