Tail pinch induced eating: psychogenetic comparison of Roman high- and low-avoidance rats.
Consummatory behavior elicited by mild tail pinch in the presence of solid food was studied in male Roman high-avoidance (RHA/Verh) and Roman low-avoidance (RLA/Verh) rats. RLA/Verh rats, characterized as the more emotional of the two rat lines, exhibited significantly shorter latencies to bite and eat solid food during tail pinch than the RHA/Verh rats. Treatment with 6, 12 and 24 mg/kg sodium pentobarbital prior to tail pinch failed to increase the elicited eating in either rat line.
