Researchers built a virtual landscape for studying how our sense of smell influences behavior, ability to navigate

According to researchers from Northwestern University, a revolutionary “smell virtual landscape” that they developed allowed them to examine “how smells engage the brain’s navigation system.” The study is the first of its kind, and research results revealed that the mammalian brain is capable of forming a map of its surroundings using only smells. The researchers said that […]
