The research team simplified this data using voxel - based morphometry, or VBM — a technique that breaks the brain into 3 - D pixels and permits rigorous statistical comparison of brain tissue density among people.

Increased computational power now allows investigation of the whole - brain correlation matrix, the temporal correlation of every voxel with every other voxel throughout the brain, and the application of multivariate pattern analysis to these correlational data.

In the new system, a mathematical model uses the fMRI signal data to construct a 3 - D map that consists of more than 1,000 voxels (pixels in three dimensions), with each voxel representing a single point of measurement of serotonin reuptake.

They pooled the CT data to produce a collective map of the cortex, which they divided into more than 3,000 three - dimensional units called voxels.

To demonstrate the predictive value of individual differences in morphometric patterns of gray matter density for intelligence, we applied voxel - based morphometry (VBM) on structural magnetic resonance imaging (MRI) data from 308 adult participants (Nooner et al., 2012).

Then a cross-correlation matrix was calculated, correlating each voxel's time course to all other voxels in the data set.

This approach seems intuitive and reasonable especially for those neuroimaging researchers who are accustomed to voxel - based analyses of neuroimaging data.

The resting - state fMRI time series data from each subject was realigned to the accompanying T1 - weighted structural image and spatially normalized to the MNI (Montréal Neurological Institute) template by the FSL software package (FMRIB; Oxford, UK), and any non-brain voxels were removed from the fMRI data.

The normalized fMRI data was masked so that only the gray matter voxels corresponding to the areas specified by the AAL (Automated Anatomical Labeling) atlas [40] were included in the subsequent analyses.

Resting - State fMRI Data Analysis Toolkit (REST) is a convenient toolkit to calculate Functional Connectivity (FC), Regional Homogeneity (ReHo), Amplitude of Low - Frequency Fluctuation (ALFF), Fractional ALFF (fALFF), Gragner causality, degree centrality, voxel - mirrored homotopic connectivity (VMHC) and perform statistical analysis.

The statistical threshold used for these data was first set to p < 0.005 (one - tailed, uncorrected) at the individual voxel level.
