*"Spatial Bayesian Latent Factor Regression Modeling of Coordinate­based
Meta­analysis Data"*

 *Abstract: *

Now over 20 years old, functional MRI (fMRI) has a large and growing
literature that is best synthesised with meta-analytic tools. As most
authors do not share image data, only the peak activation coordinates
(foci) reported in the paper are available for Coordinate-based
Meta-analysis (CBMA). Neuroimaging meta-analysis is used to 1) identify
areas of consistent activation; and 2) build a predictive model of task
type or cognitive process for new studies (reverse inference). To
simultaneously address these aims, we propose a Bayesian point process
hierarchical model for CBMA. We model the foci from each study as a doubly
stochastic Poisson process, where the study-specific log intensity function
is characterised as a linear combination of a high-dimensional basis set. A
sparse representation of the intensities is guaranteed through latent
factor modeling of the basis coefficients. Within our framework, it is also
possible to account for the effect of study-level covariates
(meta-regression), significantly expanding the capabilities of the current
neuroimaging meta-analysis methods available. We apply our methodology to
synthetic data and a neuroimaging meta-analysis dataset.



Kind regards,

Raffaella Piccarreta and Isadora Antoniano
