Biological Approach to Behavior: Chapter - Techniques used for Imagining the Brain

This brain imaging technique can show localized dynamic changes in brain activity over a given time.

• fMRI

• MRI

• PET Scan

• EEG

Which of the following techniques requires x-rays to make images.

• EEG

• fMRI

• CAT scan

• MRI

Which of the following is NOT a strength of CAT scans?

• non-invasive

• can image blood vessels

• can image soft tissues

• uses x-rays

Which imaging technique utilizes the principle that atoms (hydrogen) emit energy when placed in a magnetic field.

• MRI

• fMIR

• PET scans

• CAT scans

True or False: An individual can get numerous CAT scans without any fears of radiation exposure?

This imaging technique analyze what is known as BOLD or blood oxygen level dependent signal.

• CAT scans

• fMRI

• PET scans

• EEG

The flow of _______________ blood directly correlates with the energy being used by the brain cells, which directly correlates to the level of ___________ in a specific region of the brain.

• Oxygenated, Activity

• Glucose rich, Hydrogen

• Deoxygenated, Water

• Hydrogen rich, Activity

This imagining technique requires a radioactive tracer.

• EEG

• MRI

• PET scans

• CAT scans

True or False: EEGs can detect changes in brain activity within milliseconds but is not used to establish origin location?

What are limitations to EEG machines? (Hint: possibly more than one answer)

• Measures neural activity directly

• Not used to measure inner brain activity

• Requires training and experience in order to read results

• Gives a very crude picture in terms of localization
