Every aroma you come into contact with causes responses in your brain. Neuroscientists are using mathematical models to reproduce how the brain does this -- knowing how the brain reacts to smells may help fight against diseases of the nervous system.
“In the last 30 years, there have been multiple theories on how smell is processed,” he says. “In one model, responses to odors are represented like a snapshot of a specific moment of time. In others, the patterns evolve over time, like a symphony.”
So he and his team built a computer simulation, using only equations, that is similar to the brain’s system for smell. Then they changed the equations to test theories on how the brain works when it encounters an odor.Results suggest that the brain’s way of processing smell depends on what it needs to understand in the moment.
In other words, the brain adapts its response to what’s happening in the world around us. That’s good, because the But for now, Padmanabhan’s model is a small but important piece in decoding the larger puzzle of how the brain works.
