Characterizing pinprick-evoked brain potentials before and after experimentally induced secondary hyperalgesia.

abstract：:Different muscle targets and transcription factor expression patterns reveal the presence of motor neuron subtypes. However, it is not known whether these subtypes also differ with respect to electrical membrane properties. To address this question, we studied primary motor neurons (PMNs) in the spinal cord of zebrafi...
