Research Interests

Gerard Martin


My long term goal is to provide behavioral analyses and theories that allow us to understand the learning deficits that are produced by damage to brain structures. My recent work has focused upon the processes underlying spatial navigation.

The ability to navigate throughout the environment is important for the survival of most animals. To this end animals have developed sophisticated navigational strategies. My research analyzes the components of these strategies and examines the neurobiological instantiation of these strategies. My research, then, contributes to our understanding of one of the most fundamental cognitive processes in animals, spatial knowledge. It also enables us to understand a variety of animal behavioral tests that are used to model learning and memory deficits in humans.
