Forming New Short-term Memories (1)
Professor Ron Davis discusses how his lab observed that short term memories are formed through the recruitment of new synapses.
One of the more recent observations we made is that short-term memories in the fruit fly are formed through the recruitment of new synapses into how sensory information is represented. So, as we (or any animal) learns environmental information or sensory information such as olfactory information, odors, or visual information itâ€™s represented by the activity of synapses in the brain. So we perceive an odor and there are certain numbers of synapses that become activated that represent a specific odor. After we have learned something about that odor, we have discovered that new synapses are added to that representation of the odor.

Professor Ron Davis discusses the attributes that make the fruit fly a good model for studying memory in humans.
1095. Forming New Short-term Memories (3)
Professor Ron Davis explains that short-term memories are formed by recruiting new synapses. It is unknown whether long-term memories are formed in the same way.
1156. Mushroom Bodies
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.
1096. The Future for Memory Research
Professor Ron Davis discusses exciting future directions in memory research.
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.
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.
1997. Learning and memory
Learning and memory are two intimately linked cognitive processes that stem from interactions with the environment (experience).
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.
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.
