Greater superficial petrosal nerve transection in rats does not change unconditioned licking responses to putatively sweet taste stimuli.
The greater superficial petrosal nerve (GSP), innervating taste buds in the palate, is known to be exceptionally responsive to sucrose, especially compared with the responsiveness of the chorda tympani nerve (CT). However, whereas transection of the CT (CTX) alone has little or no effect on unconditioned licking responses to many "sweet" stimuli, the impact of GSP transection (GSPX) alone is eq...
متن کاملThe time course of taste bud regeneration after glossopharyngeal or greater superficial petrosal nerve transection in rats.
We previously have published data detailing the time course of taste bud regeneration in the anterior tongue following transection of the chorda tympani (CT) nerve in the rat. This study extends the prior work by determining the time course of taste bud regeneration in the vallate papilla, soft palate and nasoincisor ducts (NID) following transection of either the glossopharyngeal (GL) or great...
متن کاملMorphological changes of lumbar spinal neurons after sciatic nerve transection in neonate rats
Axotomy of the sciatic nerve have been documented to cause neuronal loss, especially in newborn rats. Few works have focused on time course of neuronal loss and the type of cell death, which occurs after axotomy. Forty rat pups were anesthetized by hypothermia and the right sciatic nerve transected at five days of their age and the left side was used as control. The operated animals were sacrif...

متن کاملDifferential covariation in taste responsiveness to bitter stimuli in rats.
Variation exists in the sensitivity of individual rodents and humans to different bitter tastants. An absence of uniform correlation in responsiveness to different bitter substances across individuals within a species suggests heterogeneity in the mechanisms underlying stimulus processing within this taste modality. Here, we examined taste responsiveness of individual rats to three bitter compo...
