摘要：

A system for long-term monitoring of mouse eating and drinking behavior with 6-s resolution is described. The apparatus utilizes infrared beams to monitor activity at a single feeding port and electronic contact detector circuitry to record individual licks at two drinking ports. Eight SWR/J mice were monitored using this system and data from the last day of testing with food and water were analyzed. Mice ate an average of 4.54 +/- 0.40 g of powdered food and drank an average of 5.81 +/- 0.65 ml of water. Mice had an average of 36.25 +/- 3.96 food bouts and 32.25 +/- 7.56 water bouts lasting 3.00 +/- 0.48 and 0.88 +/- 0.35 min, respectively. Information regarding the temporal association between eating and drinking and the circadian patterns of ingestion was provided, utilizing customized software that augments the system. Important implications for the use of mice in ingestion pattern research are discussed.
