Neuropathic Pain: New Insights, New Interventions - Part III The conclusion of a three part series on Neuropathic Pain. This segment discusses the effect of neuropathic pain upon the circuits of the nervous system - and how they become altered. This alteration makes current pain management treatments ineffective. Thus it is necessary to research each type of pain individually and to find an effective treatment - based upon the rewired circuitry of the nervous system. neuropathic pain • circuits • nervous system • management • treatment

Diamond Dust: Snow Without Clouds During the depths of winter cold, we often hear some weather sage observe, "It's too cold to snow." Truth is, it is never too cold to snow. At very cold temperatures, 40 below zero (C or F) and colder, snow can actually fall out of the clear blue sky without intervening clouds, a weather condition known appropriately enough as diamond dust. weather • winter • meteorology • diamond dust • ice crystals |
