Study Summary

This trial will test whether increasing brain insulin can help regulate blood flow and the nervous system.

Who is the study for?
This trial is for healthy adults aged 18-45, with a BMI of 18-30 kg/m2 who don't smoke or use nicotine and are not pregnant or breastfeeding. It's not suitable for those with respiratory, metabolic, cardiovascular, autonomic diseases, autoimmune disorders, bleeding/clotting issues, stroke/neurovascular disease history, substance abuse problems including alcoholism and smoking history.Check my eligibility
What is being tested?
The study investigates the effects of increased brain insulin on sympathetic nervous system activity and blood flow in the body and brain. Participants will undergo carbon dioxide breathing tests to assess neurovascular coupling after receiving human insulin intranasally.See study design
What are the potential side effects?
Potential side effects may include discomfort from nasal administration of insulin, changes in blood pressure or heart rate due to CO2 breathing tests. There might also be temporary alterations in peripheral and cerebral vasodilation.
