报告摘要
A code for episodic memories in the hippocampus of food-caching birds
Throughout each day the brain captures snapshots of distinct experiences, forming episodic memories that often last a lifetime. This function depends on the hippocampus – a brain region that is evolutionarily conserved across vertebrates. My lab studies the relationship between hippocampal activity and episodic memory using a unique model organism – the black-capped chickadee. Chickadees are specialist food-caching birds that store thousands of food items at concealed locations in their environment and use memory later in time to retrieve their caches. I will describe our effort in designing behavioral arenas and neural recording techniques to study these behaviors in laboratory conditions. I will share our discoveries of spatial representations in the chickadee hippocampus. I will also present our latest data on how neural activity in this region represents distinct memories, and how vision plays a role on this process.
Dmitriy Aronov is an Associate Professor of Neuroscience at Columbia University and an Investigator of the Howard Hughes Medical Institute. He received his Ph.D. at MIT working on the song system of zebra finches, followed by a postdoc at Princeton University working on the rodent hippocampus. In his own lab, he developed food-caching birds, chickadees, as a new model system for neuroscience research. His team develops behavioral paradigms for working on the natural behavior of these wild birds in the lab. They also work on miniaturized technologies for recording and manipulations in the chickadee brain. By using this new system, Dmitriy Aronov’s lab hopes to gain insight into the neural mechanisms of episodic memory.
