Overactivation of primary motor cortex is asymmetrical in hemiparkinsonian patients.

abstract：:The tetrodotoxin-resistant voltage-gated sodium channel Nav 1.8 is expressed only in nociceptive sensory neurons. This channel has been proposed to contribute significantly to the sensitization of primary sensory neurons after injury. We have studied the nociceptive behaviours of mice carrying a null mutation in the N...
