Age Correlation With the BOLD Signal in the Central Olfactory System of Men
| Condition | Area | MNI Coordinates (mm) | Cluster Size (voxel) | Cluster Level | Voxel Level | |||||
|---|---|---|---|---|---|---|---|---|---|---|
| x | y | z | p FWE-corr | p uncorr | p FWE-corr | p uncorr | t Value | |||
| Odorless-sniff | L-DLPFC | −30 | 42 | 16 | 67 | .838 | .481 | .590 | .001 | 3.92 |
| L-insula/L-OFC | −40 | 14 | −6 | 115 | .734 | .350 | .644 | .001 | 3.82 | |
Note: Within the male group, significant negative aging effect on the olfactory activation signal responding to odorless-sniffing was observed in some secondary olfactory structures (multiple regression, p < .005, corrected with cluster size ≥65 voxels). Coordinates are given in the left-posterior-inferior system in the Montreal Neurological Institute (MNI) brain template space. L = left. DLPFC = dorsolateral prefrontal cortex; FWE = family-wise error; OFC = orbitofrontal cortex. corr = corrected; uncorr = uncorrected.
