Strategies for Developing Animal Models of Neurotoxicant-Induced Neurodegenerative Disorders

Parallel Studies of Learning and Memory in Animals and Humans

  • Chapter
Toxin-Induced Models of Neurological Disorders

Abstract

Exposure to neurotoxic substances may play an important role in the etiology of memory impairment associated with neurodegenerative disorders. Because of this, significant effort has been devoted to developing animal models of these neurotoxin-induced disorders. In this chapter we will begin by critically reviewing some of the issues surrounding the development of animal models of neurologic conditions that may produce memory impairment. We will then argue that one important aspect of any strategy for developing neurotoxin-induced models of neurodegenerative disorders is to reduce the uncertainty involved in generalizing from animal models to human conditions. Next we will review some of our own work that has attempted to accomplish this by using a model systems approach to the study of learning and memory. The primary advantage of this approach to neurotoxicology is that it allows for the study of identically learned behaviors in animals and humans within a learning and memory paradigm whose neurobiological basis is well understood. As such, when neurotoxin-induced memory deficits are found in animal models it is possible to: (1) form testable hypotheses regarding the neurobiological basis of these deficits and (2) have a reasonable degree of certainty that similar memory deficits would occur if human exposure produced similar neurodegenerative effects.
