Preferential block of inactivation-deficient Na+ currents by capsaicin reveals a non-TRPV1 receptor within the Na+ channel.

abstract：:Pain has the capacity to interfere with daily tasks. Although task interference by pain is largely unintentional, it can be controlled to a certain extent. Such top-down control over pain has been believed to be reduced in patients with fibromyalgia (FM). In this study, we investigated task interference and distractio...
