If you are present in the kitchen while the Thanksgiving turkey is being prepared, why must you go outside for a few minutes before returning and being able to smell the cooking aromas?
What will be an ideal response?
Awareness of the aroma of cooking food is lost after a short period of exposure, by a process called central adaptation, although the sensory neurons remain active. Central adaptation involves the inhibition of nuclei along a sensory pathway. At the unconscious level, central adaptation further restricts the amount of detail arriving at the cerebral cortex to permit about 1 percent of the sensory input to reach consciousness.
