Abstract
The olfactory system universally relies on sensory input from two anatomically distinct channels (e.g., antennae, nares, nostrils). For some tasks, these separate streams of information are best kept separate, whereas for others, perception and behavior benefits from their integration. This symposium will highlight recent advances in our understanding of how olfactory information from the two channels is processed in the brain, spanning a wide range of neuroscience methods (behavior, electrophysiology, imaging, computation) and model organisms (flies, rodents, humans). First, Naz Dikecligil will present data from intracranial recording experiments in humans, showing that bilateral odor stimulation evokes temporally segregated odor representations. Second, Clara Raithel will discuss human behavioral and neuroimaging data from experiments with single-nostril odor stimulation. Next, Venki Murthy will present electrophysiology evidence on how bilateral odor information is integrated in the rodent brain. Finally, Aravi Samuel will discuss calcium imaging data from larval Drosophila, revealing laterality from sensory neurons to mushroom body output neurons. Together, this symposium will provide a cross-species overview on how lateralized olfactory information is shared across hemispheres, and how it may be kept separate, to optimally inform behavior.
