The paper replicates and extends findings showing that lifelong olfactory deprivation leads to orbitofrontal cortex morphological changes, but not in piriform cortex.

The paper compares functional connectivity in olfactory cortex between individuals with congenital anosmia and controls, finding no atypical connectivity despite lifelong olfactory sensory loss.

The paper assesses longitudinal medial temporal lobe atrophy in preclinical dementia using visual and automated methods over six years, finding that visual ratings correlate with subcortical volumes but have low inter-rater agreement.

The paper examines structural brain changes in individuals with congenital olfactory loss, finding atrophy in olfactory sulci and increased volume in medial orbital gyri, suggesting differential plasticity in secondary vs. primary olfactory cortex.
