Here we describe methods to test C. elegans associative learning and short- and long-term associative memory. These population assays employ the worms abilities to chemotax toward volatile odorants, and form positive associations upon pairing food with the chemoattractant butanone. Increasing the number of conditioning periods induces long-term memory.

Most behavior experiments for rodents were originally devised for rats. Due to the behavioral differences between rats and mice, sometimes modifications are required for mice. We present a method to test spatial working memory in mice, minimizing the stress during the working memory task.

Learning and memory are potent metrics in studying either developmental, disease-dependent, or environmentally induced cognitive impairments. Most cognitive assessments require specialized equipment and extensive time commitments. However, the shuttle box assay is an associative learning tool that utilizes a conventional gel box for rapid and reliable assessment of adult zebrafish cognition.

An Introduction to Learning and Memory

2023
Learning is the process of acquiring new information and memory is the retention or storage of that information. Different types of learning, such as non-associative and associative learning, and different types of memory, such as long-term and short-term memory, have been associated with human behaviors. Studying these components in detail helps behavioral scientists understand the neural mechanisms behind these two complex phenomena. JoVE's overview on learning and memory introduces common...

Spatial Memory Testing Using Mazes

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...

Synaptic plasticity makes communication between neurons more effective when their activity becomes repeatedly coordinated. Hebbian processes are one example: connections strengthen when neurons activate together, increasing the likelihood that activity related to one learned element will engage activity linked to another. This neural change provides a mechanism for forming associations that can later guide retrieval.
The hippocampus helps bind separate elements of an experience during learning, allowing related details to function as a connected episode. Distributed cortical networks contribute to longer-term storage and retrieval, so the information is not restricted to one brain location. This division helps explain how associations can remain available after the initial experience has passed.
Associative memory can be retrieved from partial cues because linked neural representations allow one element to reactivate information connected with it. Distributed cortical networks support this cue-based access, while the hippocampus contributes to binding the elements of the original experience. The same process also helps explain why an incomplete reminder can recover context or related details.
Memory errors can arise when retrieval from a partial cue activates related information that does not exactly match the original experience. Because associations connect elements across an experience, recall may depend on which linked representation is reactivated. Examining these outcomes helps researchers study not only successful remembering, but also how context and related information shape inaccurate recall.
Studies can show how the surrounding context influences which stored information becomes accessible from a cue. Since the hippocampus binds elements of an experience and cortical networks support retrieval, changes in contextual information may alter what is recalled. These findings help connect neural mechanisms with observable differences in remembering the same learned material under different conditions.
Associative memory provides a framework for investigating how learning, contextual recall, and memory errors may be altered in these conditions. Research can use the involvement of hippocampal binding, synaptic plasticity, and distributed cortical storage to relate behavioral memory patterns to brain processes. This makes the topic relevant to understanding disease-related memory changes and trauma-linked recall.
