Prefrontal	17 (7–36)	107 (71–150)*	79 (43–115)*	68 (38–177)*	35 (14–56)	17 (5–31)
Precuneus	4 (0–32)	2 (0–100)	0 (0–96)	9 (0–87)	7 (0–43)	0 (0–33)
Sensory/motor	16 (9–23)	41 (30–115)*	57 (27–95)*	43 (26–101)*	32 (17–40)	15 (9–30)

Values are medians (range).

^*Significantly more activated voxels with flavored stimuli than dry swallow in prefrontal and sensory/motor regions and swallowing network (P < 0.05).
