2-Minute Neuroscience: Neuroimaging
In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss neuroimaging, covering four of the most common types of neuroimaging: computerized axial tomography (CAT), magnetic resonance imaging (MRI), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI). CAT and MRI are methods of imaging the structure of the brain while PET and fMRI are methods of imaging the activity or function of the brain.

fMRI and the BOLD Signal
This video describes the principal of the blood-oxygen-level dependent (BOLD) signal in functional Magnetic Resonance Imaging (fMRI). Researchers use modern fMRI to detect changes in the brain's blood flow and determine which regions are most active.
Using our innovative visualization techniques, we created 3D visualizations depicting the changes in brain activity measured by fMRI. We then zoom down to the cellular level to illustrate how neurons fire and blood flow increases.

Does Demetrious Johnson have CTE? - Doctor Explains 10 year Brain Study
Demetrius Johnson, a top MMA fighter, recently retired and has been involved in important research on CTE (chronic traumatic encephalopathy).
What is CTE?
Chronic traumatic encephalopathy (CTE) is a brain disease caused by repeated head trauma. Key features include:
* Chronic effects over time
* Traumatic injuries
* Brain degeneration
CTE Symptoms
CTE symptoms are divided into three categories:
1. Neuropsychiatric: Impulsivity, depression, substance abuse.
2. Cognitive: Memory and attention problems.
3. Motor: Coordination issues, Parkinson-like symptoms.
Diagnosis Challenges
Diagnosing CTE is difficult; current neuroimaging techniques like CT and MRI are not definitive. Diagnosis typically occurs post-mortem via autopsy, which identifies brain degeneration and P-TAU deposits.

Christopher Hess, MD, PhD, Neuroimaging Part 1: Physical Principles of Neuroimaging
Computed Tomography is based on X-Ray technology. X-rays, when passed through an object, are attenuated -- yielding an image of the underlying structure. CT uses a similar mechanism, in which x-rays are passed through a slice, rotated around the patient, then combined to create a 2-dimensional image. A 3-dimensional volume is captured as the machine rotates around the subject.
Magnetic Resonance Imaging is created by a superconducting magnet. The patient is inserted into a larger bore than in a CT scan. The gradient coils on the inside allows for spacial localization. The patient is placed in a head coil then moved into the bore. Different flavors of MRI's include T1, T2, Contrast, Diffusion, Perfusion, and Angiography.

How do scientists use neuroimaging?
How do scientists use neuroimaging? Whether it’s a CT scan, MRI, fMRI, PET (or another acronym), neuroscientists can learn so much from these images about the structure, function, and activity of the brain.
At the Kavli Institute for Systems Neuroscience at NTNU, Tobias Navarro Schröder uses neuroimaging to understand how the human brain uses visual information to map the surrounding environment and remember past events.

TRANSCRIPT:
Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss neuroimaging. I will cover a few of the most common types of neuroimaging: CAT scans, MRI, PET scans, and fMRI.
Some neuroimaging techniques allow us to see the structure of the brain, while others allow us to look at brain activity or function. Computerized tomography, also known as computerized axial tomography, is a type of structural neuroimaging. It is usually called a CAT or CT scan. It involves taking a series of x-ray images from various locations around the head. These images can then be combined to construct an image of the brain. The resolution of CT images is not that high, but they can visualize any major structural problems with the brain, such as a tumor.
Magnetic resonance imaging, or MRI, involves applying a combination of magnetic fields and radiofrequency energy waves to the brain. Hydrogen atoms respond to the magnetic fields and radiofrequency pulses by emitting energy. The MRI machine receives this energy and can tell what part of the brain it came from. A computer can use that information to reconstruct an image of the brain with high spatial resolution.
Positron emission tomography, or PET scanning, is a way of imaging brain function. To do a PET scan, a patient is injected with a radioactive substance that emits positrons, which then emit gamma rays when they collide with electrons in brain tissue. These gamma rays are detected by the PET scanner. Because the radioactive substance was injected into the bloodstream, what the PET scanner is detecting is the movement of blood throughout the brain. Blood flow to an area of the brain increases when that area is active, so PET scanning creates an image that highlights the areas of the brain that are being used the most while the person is in the scanner.
Functional MRI, or fMRI, uses a similar approach to MRI but focuses on the different responses oxygenated and unoxygenated blood make to magnetic fields and radiofrequency energy. fMRI uses what is called blood-oxygen-level-dependent contrast , or BOLD, to identify changes in blood flow in the brain, and thus to identify areas of the brain that are most active. fMRI allows one to image brain function without having to inject anything, and it provides high resolution MRI images at the same time as it provides a functional image.

Demetrius Johnson, a top MMA fighter, recently retired and has been involved in important research on CTE (chronic traumatic encephalopathy).
What is CTE?
Chronic traumatic encephalopathy (CTE) is a brain disease caused by repeated head trauma. Key features include:
* Chronic effects over time
* Traumatic injuries
* Brain degeneration
CTE Symptoms
CTE symptoms are divided into three categories:
1. Neuropsychiatric: Impulsivity, depression, substance abuse.
2. Cognitive: Memory and attention problems.
3. Motor: Coordination issues, Parkinson-like symptoms.
Diagnosis Challenges
Diagnosing CTE is difficult; current neuroimaging techniques like CT and MRI are not definitive. Diagnosis typically occurs post-mortem via autopsy, which identifies brain degeneration and P-TAU deposits.
Research Overview
Johnson participates in the study "Blood Biomarkers and Neurodegeneration in Individuals Exposed to Repetitive Head Impacts," involving:
* Active MMA Fighters
* Active Boxers
* Retired Boxers
* Control Group
Study Methods
Since 2011, participants have annual assessments including:
* Blood samples
* MRI brain imaging
* Cognitive testing with CNS Vital Signs
Biomarker Analysis
Blood tests look for biomarkers like GFAP (Glial Fibrillary Acidic Protein), indicating brain injury. This research may improve future CTE diagnosis.
Does Demetrius Johnson Have CTE?
Currently, it’s unclear if Johnson has CTE. His cognitive test results are encouraging, showing improvements in IQ and speech. Definitive answers may come with further research or posthumous brain donation.
This research aims to advance understanding and diagnosis of CTE in athletes.

Computed Tomography is based on X-Ray technology. X-rays, when passed through an object, are attenuated -- yielding an image of the underlying structure. CT uses a similar mechanism, in which x-rays are passed through a slice, rotated around the patient, then combined to create a 2-dimensional image. A 3-dimensional volume is captured as the machine rotates around the subject.
Magnetic Resonance Imaging is created by a superconducting magnet. The patient is inserted into a larger bore than in a CT scan. The gradient coils on the inside allows for spacial localization. The patient is placed in a head coil then moved into the bore. Different flavors of MRI's include T1, T2, Contrast, Diffusion, Perfusion, and Angiography.

How do scientists use neuroimaging? Whether it’s a CT scan, MRI, fMRI, PET (or another acronym), neuroscientists can learn so much from these images about the structure, function, and activity of the brain.
At the Kavli Institute for Systems Neuroscience at NTNU, Tobias Navarro Schröder uses neuroimaging to understand how the human brain uses visual information to map the surrounding environment and remember past events.
