Diving into the noradrenergic system : Role of the alpha2C-adrenergic receptors NA2C-TEP-IRM
This study aims to understand how a brain system, called the noradrenergic system, works, especially focusing on something called alpha2C-adrenergic receptors. Researchers use two types of brain scans: PET scans and MRI scans. They'll use these to look at a small, important area in the brain called the locus coeruleus (pronounced LOH-kus suh-ROO-lee-us). The study will explore how measurements from these scans relate to different abilities like thinking, memory, language, mood, sleep, and even pain. By understanding this system better, scientists hope to gain insights into various brain conditions and potentially find new ways to help people in the future. Anyone aged 18 or over can potentially take part.
At a glance
What is this study about?
This research is looking closely at a specific communication network within your brain called the noradrenergic system. Think of it like a control centre that helps manage many important body functions, including how you pay attention, your mood, how you react to stress, and even your sleep. Within this system, there are tiny switches called alpha2C-adrenergic receptors, and this study specifically wants to understand what role these switches play.
To do this, the researchers will use two special types of brain scans. One is a PET scan, which helps them see how these tiny switches are working. The other is an MRI scan, which gives detailed pictures of a small, important part of your brain called the locus coeruleus (pronounced LOH-kus suh-ROO-lee-us) – this area is like a key hub for the noradrenergic system. By putting these two types of information together, they hope to get a very clear picture of how this system is functioning.
The main goal is to see if the activity in this brain system is connected to various abilities and feelings. They'll check how it relates to things like your memory, how you think and solve problems, your language skills, your mood, how well you sleep, and even how you experience pain. Understanding these connections could help scientists learn more about different brain conditions and potentially lead to new and better ways to help people in the future.
Key takeaways
- Studies a key brain system involved in mood, attention, and sleep.
- Uses special brain scans (PET and MRI) to look at brain activity.
- Explores links between brain activity and thinking, memory, and emotions.
- Aims to improve understanding of various brain conditions.
- Open to adults aged 18 and over.
Who may be eligible?
This study is open to both men and women who are at least 18 years old. There isn't an upper age limit mentioned, so older adults can also be considered.
The researchers will need to check your medical history and current health carefully to make sure that taking part in the study is safe and appropriate for you. They will look to see if you have any pre-existing conditions or are taking any medications that might affect the study results or your safety.
Specific details about who cannot take part – for example, if you have certain medical conditions, are pregnant, or have metal implants that prevent an MRI scan – will be discussed by the study team. It's always best to chat with your doctor and the study team to see if this research is a good fit for you.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Are you comfortable having brain scans (PET and MRI)?
- Are you willing to complete memory and mood tests?
- Are you able to visit the research centre for appointments?
- Do you have any metal in your body that would prevent an MRI scan?
What does participation involve?
If you decide to take part in this study, you will likely have several appointments at the research centre. These will involve having two types of brain scans: a special PET scan and an MRI scan. For the PET scan, you'll receive a very small, safe amount of a substance called [11C]ORM-13070, which helps the researchers see the brain activity they're interested in.
Beyond the scans, you'll also complete various assessments. These will include tests to check your memory, thinking skills, and language abilities. You'll also be asked questions about your mood, how well you sleep, and any pain you might experience. These tests might include filling out questionnaires or doing simple tasks.
The total number of visits, the exact length of each visit, and the overall duration of your participation will be explained in detail by the study team. Usually, there's no medication involved for you to take home, but you will receive the injection for the PET scan during one of your visits. There might be some follow-up appointments, but this will be made clear.

Common questions
What is the noradrenergic system?
It's a communication network in your brain that helps control attention, mood, stress response, and sleep.
What are alpha2C-adrenergic receptors?
These are like tiny switches within the noradrenergic system that the study wants to understand better.
What is a PET scan and an MRI scan?
PET scans help researchers see how your brain is working, while MRI scans give detailed pictures of your brain's structure.
Will I have to take any medication?
You will receive a special substance for the PET scan, but you won't typically need to take medication at home for this study.
How long will I be involved in the study?
The study team will tell you the exact number of visits and the total time commitment during your first meeting.
