摘要: Abstract The importance of the peripheral nervous system to ventral rubbing was investigated by inhibiting cutaneous feedback from surface. relationship between and presence gland pad also assessed. Twenty-three adult male gerbils were randomly assigned excision, sham or intact groups. animals then two matched drug treatment groups which received injections 2% lidocaine HCL (Xylocaine) physiological saline on alternating trials. Gland excision had no effect rubbing, locomotor activity, sniffing. There a significant decrease in increase activity Xylocaine trials; there difference sniffing frequency. Results interpreted as an interaction central mechanisms regulation rubbing.
