Diurnal Differences in Toluene Induced Reward-Seeking Behavior Between Melatonin-Proficient (C3H) and Melatonin-Deficient (C57) Mice

Objectives: Abuse of organic volatile substances (inhalants) has become a social health problem that is increasing in the recent years. Toluene as a prototype of inhalants can be use via inhalation, intraperitoneal or intravenous for experimental research on rodents. A conditioning paradigm of toluene inhalation was developed the rewarding effect in mice and rats. Aim of this research, investigation of toluene induced reward-seeking behavior at day and night order in melatonin proficient (C3H) and deficient (C57) mice.
