[Dualist nature of cutaneous pain. Review of the literature]. / Natureza dualista da dor cutanea. Revisão da literatura.

The double nature of the cutaneous pain is evident since the peripheral level, projecting in different structures of the central nervous system. In certain levels their ways converge, in other ones they diverge. Their characteristics appear since the stimulation, going beyond through different properties of receptive fields, and reaching particular associated responses. They seem also different in the ways of blocking and have interactions between them and with the dorsal column and lemniscal system, that conveys the sensibility of fine touch.
