Cellular Mechanisms Contributing to the Functional Heterogeneity of GABAergic Synapses.

abstract：:The dorsal root ganglion (DRG) contains heterogeneous populations of sensory neurons including primary nociceptive neurons and C-fibers implicated in pain signaling. Recent studies have demonstrated DRG hyperexcitability associated with downregulation of A-type K(+) channels; however, the molecular correlate of the co...
