RESUMO

A natureza dualista da dor cutânea aparece desde o nível periférico, projetando-se em diferentes estruturas no sistema nervoso central. Em certos pontos há convergência, em outros há divergência das vias. Suas características aparecem desde as formas de estimulação, passando pelas propriedades diversas dos campos receptivos, e associadas a respostas particulares. Parecem também diferentes nas formas de bloqueio e exercem interações entre si e com os sistemas da coluna dorsal-lemniscal, que conduz a sensibilidade do tato fino.


SUMMARY

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.
