Intraneural stimulation of the human vagus nerve
A group of researchers in the Department of Neuroscience at Monash University are interested in learning about communication between the stomach and the brain. Specifically, they want to know what information is passed between the two when food is eaten. To determine this, they are using a state-of-the-art electrode array that measures stomach muscle activity in humans while simultaneously recording activity from the vagus nerve.
What is involved?
Under ultrasound guidance, a fine tungsten microelectrode (like an acupuncture needle) will be inserted through the skin of your neck into the vagus nerve. This will be used to record electrical activity in the nerve. Simultaneously, stomach motility will be measured by the placement of electrodes on your abdomen. We will then ask you to drink a nutritional shake (Ensure) to stimulate the stomach and, by extension, the vagus nerve. The procedure is well tolerated, but you shouldn’t volunteer if you are not comfortable with needles.
Who can participate?
Healthy individuals aged between 18 and 60 years.
How much time is required?
An experiment typically takes 3 hours, for which you will be reimbursed $25 per hour for your time.
