Five experts respected for their work in the development of animal models of alcohol craving offer their perspectives in a roundtable discussion format. The panel members discuss the various definitions and theories of alcohol craving and the benefits and limitations of using animal models to study alcohol craving in humans. Animal models have helped further the understanding of craving by providing information about behavior associated with craving. Animal models do have limitations, however. The fact that animals cannot "talk" about their feelings poses difficulties for researchers seeking to map an animal analog of craving onto the human experience.
