In multi-voxel pattern analysis (MVPA), researchers ________.
A) first collect fMRI data from several instances of the same cognitive event, then a computer program compares the voxel (tridimensional pixel) activity across the different instances of the same event to find patterns
B) first collect fMRI data from a single instance of a cognitive event, then a computer program compares the voxel (tridimensional pixel) activity to find patterns
C) first collect fMRI data from several instances of the same cognitive event, then a computer program compares the voxel (tridimensional pixel) activity across the different instances of the same event to find lack of patterns
D) conduct brain imaging technique that allows recording in free-moving animals

Question

Quizplus · Accepted Answer

In multi-voxel pattern analysis (MVPA), researchers collect functional magnetic resonance imaging (fMRI) data from several instances of the same cognitive event. Then, using computer algorithms, they compare the activity of voxels (three-dimensional pixels) across these different instances to identify patterns of brain activity associated with the cognitive event. This approach allows for the detection of distributed patterns of activity that might not be apparent when examining voxel activity in isolation.
