Answer:
Smell does not travel through the thalamus.
Explanation:
The thalamus is in charge of integrating sensorial information on its way to the cortex.
Smell si the only sense which travels directly to the cortex, avoiding integration in the thalamus. This is because the olfactory bulbs, the structures which codify the smell information are situated directly on the brain.
This is why smelling a familiar scent can spring up memories more than any other sense.
