A computerized system for the continuous recording and analysis of feeding, drinking, diuresis, and locomotor activity.
A system has been designed to study the intake of liquids and solid foods in rats that allows for the analysis of feeding and drinking episodes over time. In addition, it monitors locomotor activity and diuresis. This system is particularly useful for the study of the differential effects of drugs on various parameters of feeding and drinking. Because it allows for the monitoring of all behaviors for periods of 24 consecutive hours without disturbing the animals, it can be applied to the study of light/dark cycles of ingestive behavior. The apparatus consists of rat cages (equipped with photocells, bottles, electronic balances, and a funnel to collect urine), computer interfaces, an AT-compatible microcomputer for data collection, and a VAX system for analysis.
