The process of spreading the activation of one voxel into neighbouring voxels is known as:
A) Stereotactic normalisation
B) Signal-to-noise correction
C) Random field theory
D) Smoothing

Question

Quizplus · Accepted Answer

The process described is the smoothing of voxel data, which involves spreading the activation of one voxel into its neighboring voxels. This is done to reduce noise and increase the sensitivity of detecting true signals in neuroimaging data. Stereotactic normalisation involves aligning brain images to a common coordinate system, signal-to-noise correction involves boosting signal strength and reducing noise, and random field theory is a statistical method used to correct for multiple comparisons in neuroimaging data.
