Finger gnosis is the ability to mentally represent one’s fingersas distinct from one another in the absence of visual feedback.In the current paper, we conducted a quantitative meta-analysis of imaging data, using activation likelihoodestimation, to determine the neural correlates of finger gnosis.Fourteen studies contributed 294 activated foci from 225participants for analysis. The meta-analysis yielded sevenpeaks of activation located within the frontal-parietal network(i.e., medial frontal gyrus, pre- and post-central gyrus, andinferior parietal lobule) and cerebellum (i.e. culmen). Aqualitative comparison of the findings of our meta-analysiswith single-experiment fMRI investigations of finger gnosis(Andres et al., 2012; Rusconi et al., 2014) suggests thatexperimentalists’ choices of primary and control tasks haveinfluenced our understanding of the neural substrateunderlying finger gnosis. Our results may aid in the designand interpretation of behavioural and imaging experiments aswell as inform the development of computational models.
