Introduction to Brain Scans for Psychology Students - CT, MRI, fMRI, PET - Neuroscience

The video explores various brain scanning technologies used by psychologists and neuroscientists to study the brain's structure and function without invasive procedures. It covers structural scans like CT and MRI, and functional scans like fMRI and PET, highlighting their uses, differences, and costs. The video concludes with the impact of these technologies on neuroscience advancements.

What are the two main purposes of brain scans?

• To assess brain size and weight

• To analyze brain structure and function

• To measure brain temperature and pressure

• To detect brain waves and signals

What does a CT scan primarily use to create images of the brain?

• Magnetic fields

• Ultrasound waves

• Radioactive substances

• X-ray beams

How does an MRI scan differ from a CT scan?

• It uses sound waves instead of X-rays

• It uses heat waves instead of X-rays

• It uses a magnetic field instead of X-rays

• It uses light waves instead of X-rays

What does the 'F' in fMRI stand for?

• Fast

• Functional

• Focused

• Flexible

Why are PET scans considered invasive?

• They use high-frequency sound waves

• They require a long recovery time

• They involve injecting a radioactive substance

• They require surgery

What is a major limitation of PET scans?

• They provide less detailed images than CT scans

• They are not suitable for children or premenopausal women

• They cannot be used on adults

• They are more expensive than MRI scans

What is a significant benefit of brain scanning technologies?

• They have led to advancements in understanding human functions

• They are inexpensive to operate

• They are portable and easy to transport

• They can be used without any training
