Searchlight analysis: Promise, pitfalls, and potential (2013, background): “Prior reports in the literature have documented the failure of weakly informative areas to be detected in searchlight analysis, mirroring our experience that widespread, weakly informative areas are common in fMRI datasets (see also Gonzalez-Castillo et al., 2012).”
Questions and controversies in the study of time-varying functional connectivity in resting fMRI (2020, unknown): “…of studies make use of continuous task paradigms in which task demands change over the course of a single scan (Gonzalez-Castillo et al., 2019; Gonzalez-Castillo et al., 2012; Xie et al., 2017 states (as imposed by the experimenter or inferred from analysis of behavior), the validation…”
The relation between statistical power and inference in fMRI (2017, background): “Small effects will still escape notice if the data are insufficiently numerous to bring them out, but no lowering of the standard of significance would meet this difficultyº (p. 45; [28]). see reference [22] for a compelling empirical demonstration).”
The effect of resting condition on resting-state fMRI reliability and consistency: A comparison between resting with eyes open, closed, and fixated (2013, background): “While it is unlikely that two areas are completely unconnected (e.g. see Gonzalez-Castillo et al., 2012), the ICC of weakly connected regions are more heavily influenced by noise.”
A massive 7T fMRI dataset to bridge cognitive neuroscience and artificial intelligence (2021, background): “Reminiscent of past datasets employing extensive sampling of individuals 40 , the current results suggest that the extent of cortex engaged by basic memory processes is much more widespread than previously appreciated, although a careful consideration of effect sizes would be important for a full…”
Shape shifting pain: chronification of back pain shifts brain representation from nociceptive to emotional circuits. (2013, background): “Recent evidence shows that increasing the number of subjects in functional MRI can lead to the identification of more extensive brain activity (Gonzalez-Castillo et al., 2012).”
Groupwise whole-brain parcellation from resting-state fMRI data for network node identification (2013, unknown): “Such high values of reproducibility not only add confidence to these findings, but the relative consistency of the reproducibility curve (across the range of K-values) also supports the hypothesis that the brain indeed operates at multiple scales (Gonzalez-Castilloa et al., 2012).”
