Thalamus
Explanation :
The medulla oblongata: Contains centers for the control of vital processes such as heart rate, respiration, blood pressure, and swallowing.
So it could be either.
The thalamus: is a sensory relay in visual, auditory, somatosensory, and gustatory systems.
They both are not directly involved because the medulla oblongata is not anything to do with the brain and the thalamus is to do with the brain but another part of the brain. The thalamus sends information that can be stored in the memory, so it is not direct involvement.

I encourage you to take both possibilities into account.
Hope this helps!
