25	26 CBS Seminar: Rachel … CBS Seminar: Rachel Wilson, Neural networks for navigation October 26, 2021 4:00 pm - 5:00 pm Neural networks for navigation Abstract: I will discuss unpublished work from my lab on the navigation centers in the Drosophila brain. At the core of these navigation centers is a "compass system", i.e. a ring attractor network that combines external sensory signals with internal self-motion signals to generate a continuous estimate of the fly's heading direction. First, I will show evidence that the compass system can rapidly re-learn multimodal sensory cue configurations in virtual reality environments. Second, I will describe new data showing that the learning rate in this system depends on dopamine, and dopamine release is contingent on the fly's own rotational movements. This effectively compresses compass learning into the brief periods when compass cues are being rapidly sampled, thereby preventing over-learning of static snapshots. Finally, I will show how compass system output is combined with body velocity signals to produce a topographic map of the fly's travel direction and travel speed, irrespective of the fly's heading direction. Here, travel "North" is represented equivalently, regardless of whether the fly is headed North and walking straight, or whether it is headed West and walking to the right. This representation may form the basis for computing an internal representation of the fly's recent path through the environment. You are welcome to join us, masked, live on campus, in the large lecture room, Northwest B103.
