Coordinate-Based Results in Neuroimaging Studies Summary results of functional neuroimaging studies as represented by statistical parametric images (x,y,z) (x,y,z) (x,y,z) (x,y,z) (x,y,z) (x,y,z) Reported in the literature in the form of stereotactic coordinates

Literature Search: Face Discrimination Studies BrainMap Search Criteria: Face Monitor/ Discrimination AND Normal Mapping Example Search Result: 2 Experiments Returned from 1 Publication, 8 and 6 Foci Total BrainMap Database >2K Publications >10K Experiments BrainMap search yielded 396 experiments of healthy controls that participated in a face discrimination task Paller et al., Neural correlates of person recognition, Learning & Memory, 2003 Whole brain sets of coordinates (foci) from all 396 Face Discrimination experiments visualized in the BrainMap Sleuth application
Coordinate-Based Meta-Analysis: Activation Likelihood Estimation BrainMap Search Criteria: Face Discrimination BrainMap Database >2K Publications >10K Experiments Meta-Analysis: Where do the foci converge? Reported coordinates are not treated as points but as centers of probability distributions Each foci is modeled by a 3D Gaussian distribution x Search results = 396 sets of coordinates Activation Likelihood Estimation ALE originally developed by Turkeltaub et al. (2002); has been adopted by BrainMap and revised and expanded several times (Laird et al., 2005; Eickhoff et al., 2009; 2012; Turkeltaub et al., 2012) y ALE Meta-Analysis: Face Discrimination Compute ALE scores Determine statistical significance Threshold final ALE images L R P<0.05, corrected

Summary 3. Functional Interpretation of Resting State Networks RSNs: long range, but functionally connected regions that exhibit coherent fluctuations at rest; consistently identified using ICA ICA is a popular method of identifying RSNs to study the human connectome Functional interpretation of networks is problematic given the nature of resting state fmri data Components are typically loosely grouped by anatomy (e.g., basal ganglia, frontal-parietal, cerebellar ) or function (e.g., sensorimotor, visual, attention, default mode, executive However, a recent neuroinformatics technique that utilized the BrainMap database offers a different human connectome approach... studies (brainmap.org/icns) Designed to serve as a resource for data interpretation of ongoing RSN and other
