Fly Memory: A Mushroom Body Story in Parts
نویسنده
چکیده
Recent studies on the compartmentalization of fly mushroom bodies show that learning and memory in Drosophila are not as simple as might be expected for an organism with such a tiny brain.

Do the right thing: neural network mechanisms of memory formation, expression and update in Drosophila
When animals learn, plasticity in brain networks that respond to specific cues results in a change in the behavior that these cues elicit. Individual network components in the mushroom bodies of the fruit fly Drosophila melanogaster represent cues, learning signals and behavioral outcomes of learned experience. Recent findings have highlighted the importance of dopamine-driven plasticity and ac...

متن کاملMemory Elicited by Courtship Conditioning Requires Mushroom Body Neuronal Subsets Similar to Those Utilized in Appetitive Memory
An animal's ability to learn and to form memories is essential for its survival. The fruit fly has proven to be a valuable model system for studies of learning and memory. One learned behavior in fruit flies is courtship conditioning. In Drosophila courtship conditioning, male flies learn not to court females during training with an unreceptive female. He retains a memory of this training and f...
متن کاملMushroom-Body Memories: An Obituary Prematurely Written?
Studies on insect olfactory learning have established the mushroom bodies as key brain structures for the formation of long-term memory (LTM). Two new neurons in the fly brain are reported now as essential sites for LTM formation, while mushroom bodies are claimed to be unnecessary to this end.
متن کاملOlfactory learning skews mushroom body output pathways to steer behavioral choice in Drosophila
Learning permits animals to attach meaning and context to sensory stimuli. How this information is coded in neural networks in the brain, and appropriately retrieved and utilized to guide behavior, is poorly understood. In the fruit fly olfactory memories of particular value are represented within sparse populations of odor-activated Kenyon cells (KCs) in the mushroom body ensemble. During lear...
