Abstract

The present study was undertaken to examine the hypothesis that $\mu$-opioid receptors play a crucial role in behavioral sensitization to nicotine using $\mu$-opioid receptor knockout mice. All mice were treated acutely or repeatedly with nicotine 0.05 mg/kg twice daily for 7 consecutive days. The mice were challenged with nicotine on day 11. And locomotor activity was measured for 30min. (omitted)
