Once we obtained the learned dictionary matrix D and coefficient matrix ( alpha ), we mapped each row in the α matrix back to the brain volume and examine their spatial distribution patterns, through which functional network components are characterized on brain volumes [27].
For each brain structure volume we calculated the volume of the remaining brain as a log-transformed difference from total brain volume, and used these volumes to account for the scaling of brain components with total brain volume [40].
Intracranial volume was calculated based on total brain volume and hippocampal volume as a percentage of total intracranial volume.
SIENAX registers the individual scan to the standard space brain and then converts the individual brain volume to a normalized brain volume and allows global measures of normalized brain volume (NBV) and the selective evaluation of normalized cortical volume (NCV).
As compared with the controls, the global brain growth in adolescents with high functional autism and Asperger's syndrome may not be abnormal whereas their regional brain volumes and concentrations should have differential age-related changes.
The present study focused on children with and without a history of preschool onset MDD (PO-MDD) and directly examined the relations between hippocampal volume and functional brain activation to affect-eliciting stimuli.
First, functional data were time corrected for differences in acquisition time between slices for each whole-brain volume and realigned to correct for head movement.
In addition to the alteration of the left BA38 as reported by this study, previous interictal studies usually found volume and functional alteration in brain stem, thalamus, anterior cingulate cortex, insula, prefrontal cortex, etc., indicating the involvement of multiple brain regions in migraine processing network [5, 6].
To determine the protective effect of the treatments, brain and serum glutamate levels, serum GOT activity, infarct volume and functional deficit were measured in the experimental animals.
For the purpose of the first experiment ('gaze following' paradigm) 10,364 whole brain volumes in 80 functional runs (see 'Visual stimuli' section for definition of a single functional run) were scanned in six scanning sessions (separate days of measurement) in monkey M1, using the bilateral coil.
