AP Psych Unit 1 Review (different brain scans)

Electroencephalogram (EEG)

is an amplified recording of the waves of electrical activity sweeping across the brain’s surface

detects and investigates epilepsy

Magnetoencephalography (MEG)

is a brain-imaging technique that magnetic fields from the brain’s natural electrical activity

to help plan brain surgeries for epilepsy and tumor removal

understand how certain tasks influence brain activity

Computed Tomography (CT)

x-ray  photographs taken from different angles and combined by computer into a composite representation of a slice of a brain’s structure

identifies disease or injury within various regions of the body

(PET) Scan

 is a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task

diagnose, monitor and treat a variety of conditions and diseases

MRI

 is a technique that uses   magnetic fields and radio waves to produce computer-generated images of soft tissue

scans show brain anatomy

Functional MRI (fMRI)

 is a technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans

*scans show brain function as well as structure
