Question

Quizplus · Accepted Answer

The olfactory system is the only sensory system in which the afferent fibers do not cross. The olfactory neurons directly project to the olfactory bulb on the same side of the brain as the nostril that detected the odor. This is unique compared to other sensory systems, such as vision and touch, where the afferent fibers cross to the opposite side of the brain.
