Prazo |
|---|---|---|
|
Visual interoception task
Prazo: Day 1, visit 1, 30-minute scan and visit 2 (within approximately two weeks of day 1), 30-minute scan
|
The study team will be investigating brain activity and connectivity during an interoception task.
This will be measured via functional magnetic resonance imaging (fMRI) which is able to measure blood flow to regions of the brain.
|
Day 1, visit 1, 30-minute scan and visit 2 (within approximately two weeks of day 1), 30-minute scan
|
|
Resting state connectivity
Prazo: Visit 2 (second visit, within approximately 2 weeks of day 1 of the study), 60 minute scan.
|
Change in brain activity during rest pre and post prandially using functional magnetic resonance imaging (fMRI).
|
Visit 2 (second visit, within approximately 2 weeks of day 1 of the study), 60 minute scan.
|
|
Gastric peristaltic velocity
Prazo: 30 minutes (only in Visit 2, within approximately two weeks of Visit 1)
|
MRI-derived gastric motility outcome
|
30 minutes (only in Visit 2, within approximately two weeks of Visit 1)
