The highest degree of pain localization comes from which of the following?
In general, the sensation of pain is poorly localized. However, when a tactile receptor and a pain receptor are stimulated simultaneously, the pain sensation is localized with greater accuracy.
Simultaneous stimulation of free nerve endings and tactile fibers
Stimulation of free nerve endings by bradykinin
Nerve fibers traveling to the thalamus by way of the paleospinothalamic tract
Stimulation of d-type A fibers
