The reason that certain odors can initiate behavioral and emotional reactions is because the olfactory pathway is connected directly to the occipital lobe, the sense of olfaction occurs immediately at the olfactory epithelium, the olfactory pathway is connected directly to the medulla oblongata, olfactory sensations are interpreted at the prefrontal cortex, and there are widespread olfactory associations within the hypothalamus and limbic system.

How does the input of olfactory information to the brain differ from other sensory input pathways? a. it does not require the cortex for higher order processing. b. direct connections to the thalamus are not made before information reaches the cortex. c. the first direct connection is to the thalamus and not to the medulla. d. prior to making connections with the medulla, sensory input travels through the spinal cord?
