Chapter 7: Problem 1

Match the name of each brain scan with the appropriate description: a. EEG b. \(\mathrm{fMRI}\) c. PEI 1\. By locating radiation within the brain, a computer can provide a striking picture of brain activity. 2\. Electrodes placed around the skull record the electrical signals transmitted through the brain. 3\. Provides a three-dimensional view of the brain by aiming a magnetic field at the body

Short Answer

Expert verified
Matching the brain scans with the descriptions: a. EEG matches with '2. Electrodes placed around the skull record the electrical signals transmitted through the brain', b. fMRI matches with '3. Provides a three-dimensional view of the brain by aiming a magnetic field at the body', c. PEI matches with '1. By locating radiation within the brain, a computer can provide a striking picture of brain activity'.

Step by step solution

01

Matching EEG

EEG is an acronym for Electroencephalogram. From the descriptions, the one that fits EEG is the second one which states: 'Electrodes placed around the skull record the electrical signals transmitted through the brain.' The electrodes create a graph (encephalogram) of brain wave activity.
02

Matching fMRI

\(\mathrm{fMRI}\) stands for functional Magnetic Resonance Imaging. This matches with the third description: 'Provides a three-dimensional view of the brain by aiming a magnetic field at the body.' This type of brain scan can create a three-dimensional image of the brain using magnetic fields.
03

Matching PEI

PEI refers to Positron Emission Tomography. This fits with the first description: 'By locating radiation within the brain, a computer can provide a striking picture of brain activity.' PEI scan detects radiation from the emission of positrons.
