Proportions of pruriceptive (Pruri) and nociceptive-only (Noci) VTT neurons belonging to various subclasses. A: proportions of pruriceptive (black) and nociceptive-only (red) neurons classified as wide dynamic range (WDR) or high threshold (HT) based on responses to mechanical stimulation (n = 90). B: proportions of pruriceptive and nociceptive-only neurons classified as heat responsive or nonresponsive based on responses to thermal (50°C) stimulation (n = 77). C: proportions of pruriceptive and nociceptive-only neurons recorded from superficial or deep dorsal horn (n = 81).
