Professor David Anderson explains that the mushroom body is a structure in the insect brain involved in learning and memory. It has been compared to the cerebral cortex in humans.
A mushroom body is a structure in the insect brain, which has been shown to play a key role in learning and memory in insects, particularly in fruit flies. So, that's the part of the brain where the fly can learn to recognize a particular odor and to associate it with either a bad thing or a good thing - to know whether to avoid the odor or approach the odor.

1721. 3D Gene Expression
Like all brains, insect brains have different structures that accomplish specific tasks. Dr. Josh Dubnau introduces a technique for examining gene expression in the brains of fruit flies.
1437. The Shibire Experiment
Doctor Josh Dubnau describes how he and his colleagues at Cold Spring Harbor Laboratory devised an experiment that dissociated the encoding and retrieval of memory in fruit flies.
1719. Fruit fly (Drosophila melanogaster)
The fruit fly is easy to maintain, has large numbers of offspring, and grows quickly. The fruit fly shares with humans a number of so-called “master,” or homeotic, genes.
1063. Drosophila as a Model System
Professor David Van Vactor discusses the properties that make the fruit fly (drosophila) a powerful model system.
548. Model Center
Model organisms share with humans many key biochemical and physiological functions that have been conserved (maintained) by evolution.
1361. Model Organisms (Lesson)
Students work through a series of experiments that investigate the use of model organisms in the search for a better understanding of the genes that influence memory formation.
551. Fly School
The processes used by humans to perform certain forms of learning are the same as those in many other species. Even the humble fruit fly is an excellent model of how genes affect our ability to learn.
1720. Training Flies
Many of the genes important for memory in flies are probably also important for memory in other animals, even humans. Doctor Josh Dubnau explains how the T-maze is used to test memory in flies.
1433. What are Model Systems? (1)
Doctor Josh Dubnau explains that model systems are particular species of animals that substitute for humans or other animals. For genetic and historic reasons, the fruit fly is a commonly used model.
1073. Drosophila as a Memory Model
Professor Ron Davis discusses the attributes that make the fruit fly a good model for studying memory in humans.
