Study Notes
Brain Scanning Techniques
Structural Imaging
- Magnetic Resonance Imaging (MRI) focuses on the structure of the brain.
Functional Imaging
- Functional Magnetic Resonance Imaging (fMRI) focuses on the activity of neurons during thinking, listening, or reading.
Radioactive Tracers
- Positron Emission Tomography (PET) involves injecting a slightly radioactive solution into the blood to detect brain activities.
Electrophysiology
- Electroencephalography (EEG) includes many electrodes on the scalp to provide information about brain wave activity.
Safety Precautions
- Some brain-scanning techniques, such as functional MRI (fMRI), are not safe for children and premenopausal women.
