Of all five senses, sense of smell hits the brain first. Faster than a speeding bullet, it's the Superman of Senses with a direct path to the brain. Unlike many of our other senses, the olfactory system's nerve fibers do not pass through the "switching station," known as the dorsal thalmus. Instead, these nerve fibers run directly to the limbic area of the brain, which connects to the thalmus and neo-cortex. While these words may not have any meaning to you, this bit of information is important because it's how aromas are able to affect conscious thought and reactions. The limbic system links directly to our memories, stored learned responses, emotions, and feelings.
