Cognitive systems involved in listening to SEN, rSEN, and SND
| SND | rSEN | SEN | rSEN-SND | SEN-SND | SEN-rSEN | |
|---|---|---|---|---|---|---|

| Human voice perception | − | + | + | + | + | − |
| Tonal fluctuation | + | + | + | − | − | − |

Note:—SND indicates nonvocal sounds; rSEN, reverse sentences; SEN, sentences. SND, rSEN, and SEN are in the context of subjects scanned by functional MR imaging while listening to these sounds.
