Answer to Problem 1E
Correct answer:
a. EEG | 2. Electrodes placed around the skull record the electrical signals transmitted through the brain. |
b. fMRI | 3. This technique provides a three-dimensional view of the brain by aiming a magnetic field at the body. |
c. PET | 1. By locating radiation within the brain, a computer can provide a striking picture of brain activity. |
Explanation of Solution
a. EEG - 2. Electrodes placed around the skull record the electrical signals transmitted through the brain.
The electroencephalogram (EEG) is a major brain-scanning technique used to record electrical activity in the brain by placing electrodes around the skull. The electrodes detect and record the electrical signals that are transmitted through the brain.
b. fMRI - 3. This technique provides a three-dimensional view of the brain by aiming a magnetic field at the body.
The functional magnetic resonance imaging (fMRI) is a major brain-scanning technique that provides a clear and detailed three-dimensional computer-generated image of brain structures and activity. It is a painless and safe test that uses radio waves and magnetic field to create detailed images of the brain and brain stem.
c. PET - 1. By locating radiation within the brain, a computer can provide a striking picture of brain activity.
The positron emission tomography (PET) is a major brain-scanning technique used to show biochemical activity within the brain at a particular time. This scanning process locates radiation within the brain, and then provides a striking picture of brain activity through a computer.
