Question 1

Lesion

Answer 1

Question 2

EEG (electroencephalogram)

Answer 2

an amplified recording of the waves of electrical activity sweeping across the brain’s surface. These waves are measured by electrodes placed on the scalp

Question 3

MEG (magnetoencephalography)

Answer 3

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

Question 4

PET (positron emission tomography)

Answer 4

a technique for detecting brain activity that displays where a radioactive form of glucose goes while the brain performs a given task

Question 5

MRI (magnetic resonance imaging)

Answer 5

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

Question 6

fMRI (functional MRI)

Answer 6

a technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans. fMRI scans show brain function as well as structure
