Which of the following are common goals in the statistical analysis of fMRI data?
1 / 1 point
Determining networks corresponding to brain function
Making predictions about psychological or disease states
All of these options
—————————————————————————-
3.
Question 3
Which of the following are examples of ‘nuisance regressors’ typically included in a standard GLM analysis? Check all that apply.
1 / 1 point
Head motion parameters (e.g. six regressors comprising of three translations and three rotations).
All of these options
Low frequency drift
Neuronal activation
—————————————————————————-
5.
Question 5
Signal drift in fMRI is an example of
1 / 1 point
All of these options
Low frequency drift
White noise
High frequency drift
—————————————————————————-

Question 2
Fill in the blank: The relationship between the stimulus and the BOLD response is typically modeled as the convolution of the stimulus function and the __________.
1 / 1 point
Neuronal activation
Low-frequency drift
Hemodynamic response function
Design matrix
—————————————————————————-
6.
Question 6
Why are head motion parameters typically included in the GLM analysis even though motion correction has already been performed in the pre-processing stage?
1 / 1 point
Because low-frequency drift has not been accounted for properly.
All of these options
Because so-called ‘spin-history’ artifacts may remain even after motion correction.
Because co-registration has not been performed.
