How Can An Olfactory System Deal With Fluctuations At Different Scales?

Liljenström Hans, Gu Yuqiao


Neural systems have to function efficiently in the presence of noise, which occurs at all levels of neural information processing. We use a computational model of the insect olfactory system in order to investigate how this system can deal with external and internal noise. We compare our results with previous models of the mammalian olfactory system. We address questions, such as, how can the system suppress noise, or maybe even make use of it? Could noise-induced oscillations and stochastic resonance also exist in the insect olfactory system? Our simulation results indicate a positive role for noise also in the insect olfactory system, but many questions are still open
