| Measure | Time frame |
|---|---|
| The data will consist of brain function and structure acquired by MRI. During MRI measurements for brain function measurement, a conditioning task will be performed, in which subjects will be presented with pairs of meaningless figures and positive or negative images. In some trials, the positive or negative images will be presented as subliminal stimuli and displayed for a presentation time below the visual recognition threshold (e.g., 16 ms). | — |
