Nevertheless, when genetic ablation of this population of cells is finished in adulthood, behavioral deficits were observed to mechanical but not thermal stimuli (122). An additive loss of each mechanical- and warmth-induced nocifensive behaviors was achieved following even more pharmacologic ablation of central TRPV1+ terminals, suggesting a separation of mechanical and thermal modalities in the least levels of sensory processing from the pain pathways subserved by MrgprD- and TRPV1-expressing cells (122). The extent to which this separation is preserved for other murine nociceptor populations is really a subject of active analysis.
