Which of the 5 Sensory Modalities?
 
A 7 year old boy playing and patting the pet at home while drinking a fizzy drink. His mother is baking chocolate cookies and the TV is playing a song from American Idle. Which of the following sensory modalities is related directly to the cerebral cortext without relaying in the child's thalamus?

A- Taste
B- Vision
C- Smell
D- Touch
E- Hearing

The olfactory nerve goes through the cribriform plate without relaying the thalamus so the correct answer is C

the rest do and have special relaying parts in the thalamus. also another interesting fact is that the olfactory nerves can regenerate themselves!:)
