About 30% of the population cannot detect any odor when they sniff the steroid androstenone, but they can become sensitive to its smell if exposed to the chemical repeatedly. Does this change in sensitivity happen in the nose or the brain? Mainland (2002) exposed one nostril of each of 12 non-detector participants to androstenone short periods every day for 21 days. The other nostril was plugged and had humidifie flow to prevent androstenone from entering. After the 21 days, the researchers foun 10 of 12 participants had improved androstenone-detection accuracy. This suggeste increases in the plugged nostril, whereas two had reduced accuracy. This suggested
