Running just to stand still

Sensory deprivation can result in impaired perception in most sensory modalities owing to experience-dependent changes in neural processing. Odor perception, however, appears to be relatively immune to periods of deprivation. Work in humans now suggests that this stability may be due to robust, reversible, compensatory plasticity in cortex.

Figure 1: Compensatory changes in brain regions, including the piriform cortex and OFC, may allow the olfactory system to experience prolonged periods of deprivation without marked changes in odor perception.
