Study Summary

This trial studies brain response using MRI before & after insulin doses, measuring activity & blood flow in the brain.

Who is the study for?
This trial is for healthy adults with a BMI between 18 and 35 who can lie flat for at least 2 hours. Women must be non-pregnant, surgically sterilized, or postmenopausal. Participants should be willing to stay at the research facility as required and comply with study procedures.Check my eligibility
What is being tested?
The trial is testing how different doses of insulin administered through the nose affect brain activity. This is measured using functional MRI (fMRI), which tracks blood flow and metabolism changes in the brain after treatment.See study design
What are the potential side effects?
While not explicitly listed, potential side effects may include discomfort from lying still during fMRI scans, nasal irritation from intranasal insulin delivery, or rare systemic effects of insulin.
