Hey thanks for watching! Here are the terms with some descriptions:

Electroencephalogram (EEG):
EEG is a test that records electrical activity in the brain using electrodes placed on the scalp. It measures the brain's electrical patterns, providing insight into brain function and diagnosing conditions like epilepsy.

CAT Scan (Computerized Axial Tomography):
A CAT scan, also known as a CT scan, uses X-ray technology to create detailed cross-sectional images of the body. It's particularly useful for detecting tumors, injuries, and abnormalities in various organs and tissues.

MRI (Magnetic Resonance Imaging):
MRI is a non-invasive imaging technique that uses powerful magnets and radio waves to create detailed images of the body's internal structures. It's commonly used for visualizing the brain, spinal cord, joints, and soft tissues.

PET Scan (Positron Emission Tomography):
PET scans involve injecting a small amount of a radioactive tracer into the body. This tracer accumulates in areas with high metabolic activity, such as cancer cells or brain regions involved in specific tasks. It's used to detect diseases like cancer, evaluate brain function, and assess blood flow.

fMRI (Functional Magnetic Resonance Imaging):
fMRI is a specialized MRI technique that measures changes in blood flow and oxygenation in the brain. It provides real-time information about brain activity by tracking areas that are active during tasks or stimuli. Researchers use fMRI to study cognitive processes, emotions, and neurological disorders.
