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?

i am going to guess that it is co2.
