studying the brain

Question 1

FMRI

Answer 1

Functional magnetic resonance imaging (fMRI) is a brain-scanning technique that measures blood flow in the brain when a
person performs a task. An fMRI scanner can detect these different magnetic qualities and can be used to create a moving 3D map of the
brain.

Question 2

FMRI advantages

Answer 2

one strength of fMRI, in comparison to EEG, is that it has good spatial resolution. Spatial resolution refers to the
smallest feature (or measurement) that a scanner can detect, and is an important feature of brain scanning techniques.

Question 3

EEG

Answer 3

An electroencephalogram (EEG) measures electrical activity through electrodes attached to the scalp. EEG scanners work
on the idea that information is processed in the brain as electrical activity in the form of action potentials or nerve
impulses.

Question 4

EEG advantages

Answer 4

it has good temporal resolution. Temporal resolution refers to the
accuracy of the scanner in relation to time: or how quickly the scanner can detect changes in brain activity.
