The Morris Water Maze

JoVE Science Education

The Morris water maze is one of the most widely used behavioral tests for studying spatial learning and memory. In the initial phases of this task, rodents must swim to a platform to escape from a pool of water. The platform is then hidden under the water’s surface, so that the animal is required to remember it’s location in order to escape.This simple yet powerful maze design can be used to assay cognitive function, study animal models of neurodegenerative disease, and test potential drug therapies. This video provides an introduction to the Morris water maze and the principles surrounding its use, including a discussion of the different types of memory tested in the maze, important points to consider when designing and conducting this experiment, and the procedures for setup and running of the test. Several applications of the maze are examined, such as investigating how radiation treatment may lead to memory impairment. Finally, other types of water mazes, such as the 8-arm radial maze, are introduced to show how this paradigm can be adapted to engage different types of memory.

Spatial Memory Testing Using Mazes

JoVE Science Education

Spatial learning and memory are neurological functions that allow us to remember important details associated with our environment. Scientists test this phenomenon in rodents using different types of mazes like Morris water maze, Radial water maze, and Barnes maze. By investigating spatial memory in rodents, neurobehavioral scientists can gain valuable understanding of how these processes are altered following brain damage in humans. Here, the neurobiology behind spatial memory is briefly reviewed and some general principles behind maze tests are discussed. Then, the video explains generalized protocols on how to conduct trials with specific types of mazes. Lastly, it will explain how behavioral researchers are using these tools to conduct some specific experiments.

An Introduction to the Laboratory Mouse: Mus musculus

JoVE Science Education

Mice (Mus musculus) are an important research tool for modeling human disease progression and development in the lab. Despite differences in their size and appearance, mice share a distinct genetic similarity to humans, and their ability to reproduce and mature quickly make them efficient and economical candidate mammals for scientific study.

This video provides a brief overview of mice, both as organisms and in terms of their many advantages as experimental models. The discussion features an introduction to common laboratory mouse strains, including the nude mouse, whose genetic makeup renders them both hairless and immunodeficient. A brief history of mouse research is also offered, ranging from their first use in genetics experiments to Nobel prize-winning discoveries in immunology and neurobiology. Finally, representative examples of the diverse types of research that can be performed in mice are presented, such as classic behavioral tests like the Morris water maze and in-depth investigations of mammalian embryonic development.

An Introduction to Behavioral Neuroscience

JoVE Science Education

Behavioral neuroscience is the study of how the nervous system guides behavior, and how the various functional areas and networks within the brain correlate to specific behaviors and disease states. Researchers in this field utilize a wide variety of experimental methods ranging from complex animal training techniques to sophisticated imaging experiments in human subjects. This video first offers a historical overview of some of the major milestones that lead to our current understanding of the brain’s control over behavior. Then, some of the fundamental questions asked by behavioral neuroscientists are presented, which all involve the study of neural correlates, or specific brain regions whose activation is responsible for a given function. Next, prominent methods used to answer those questions are reviewed for both human and animal subjects, such as operant conditioning and functional neuroimaging. Finally, experimental applications of these techniques are presented, including animal training using a Skinner box, and the use of electroencephalography to investigate human neurological disease.
