Resumo

Introdução. A Neurofisiologia Clínica é pesadamente baseada na in­terpretação de campos elétricos de potencial. Tais interpretações po­dem por vezes criar objetos conceituais diferentes que com o tempo acabam mostrando-se como diferentes aspectos do mesmo fenômeno. Um exemplo ilustrativo é representado pelos campos de potenciais ao redor da medula espinhal sob uma perspectiva histórica. Método. Uma breve revisão histórica é feita dos potenciais registrados ao redor da medula espinhal. Resultados. São descritos o reflexo da raiz dorsal, o potencial da raiz dorsal, o potencial de dorso medular e a despolari­zação aferente primária. Conclusão. Estes potenciais são predominan­temente diferentes aspectos do mesmo gerador – as atividades segmen­tares medulares – secundários ao registro por diferentes montagens.
