Brain regions with increased fMRI activity in patients after HA use (PA) when compared to patients before HA use (PB). The center of the cluster for each brain region is represented in Talairach coordinates (x, y, and z), followed by its respective standard deviations (in parentheses). Clusters were selected using a q[FDR] < 0.05 and a cluster size of at least 50 mm3.
| Brain region | Hem | Cluster size | Talairach coordinates | BA | ||
|---|---|---|---|---|---|---|
| x | y | z | ||||
| Superior temporal gyrus | L | 476 | −51 (5) | −1 (10) | 1 (4) | 21, 22, 41 |
| Transverse temporal gyrus | L | 178 | −42 (4) | −23 (2) | 12 (1) | 40, 41 |
| Superior frontal gyrus | L | 295 | −6 (2) | 40 (4) | 46 (3) | 8 |
| Insula | L | 109 | −39 (4) | −23 (7) | 12 (4) | 13 |
Hem = hemisphere; L = left; R = right; and BA = Brodmann area.
