Pavlovian Experiments on Locusts Provide New Clues on How Smell Works in The Brain

From the fragrance of brewing coffee to the smell of rain soaking the soil, distinguishing scents is one of the reasons that having a sense of smell is wonderful. But how smells such as coffee can be understood by our brain, no matter the season, location, or time is a complex question to answer. There's a huge number of neurons making up our olfactory bulb to help us make sense of the aromas around us. So, researchers turned to an unlikely ally – locusts – to break down how smells such as coffee always smell like coffee, despite a myriad of other smells or other environmental factors potentially getting in the way. "This feat of pattern recognition that is still difficult to achieve in artificial chemical sensing systems is performed …
