Greater hippocampal gray matter volume in subjective hyperosmia: a voxel-based morphometry study.

ABSTRACT: Subjective hyperosmia refers to a self-reported olfactory ability that is superior to a normal, intact sense of smell (normosmia), and is associated with olfactory emotional experience. The current study used voxel-based morphometry to investigate the gray matter volume (GMV) in people with self-rated hyperosmia (subjective hyperosmia, SH, N?=?18) in comparison to people with self-rated normal olfaction (subjective normosmia, SN, N?=?14). Participants' olfactory function were assessed by the extensive olfactory test battery, the "Sniffin' Sticks" test. Within the predicted brain regions (regions-of-interest analyses), the SH participants showed larger GMV of the left hippocampus as compared to SN participants (FWE corrected p?
