Modulating cortical connectivity in stroke patients by rTMS assessed with fMRI and dynamic causal modeling (2010, methodology): “Additional high-resolution T1 (MPRAGE, magnetization prepared rapid acquisition gradient echo) and FLAIR (fluid attenuated inversion recovery) volumes were acquired after the baseline fMRI scan (parameters as in Grefkes et al., 2008b).”
Coordinate-based ALE meta-analysis of neuroimaging data: A random-effects approach based on empirical estimates of spatial uncertainty (2009, methodology): “These results are in good accordance to the well established network for the control of hand movements [e.g., Grefkes et al., 2008a; Rizzolatti and Luppino, 2001; Vogt et al., 2007].”
Co-activation patterns distinguish cortical modules, their connectivity and functional differentiation (2011, background): “Among those, effective connectivity analyses, such as dynamic causal modeling (Friston et al., 2003) or structural equation modeling (Buchel and Friston, 1997), allow the investigation of taskdependent influences among cortical areas (Grefkes et al., 2008).”
Dynamic causal modeling of cortical activity from the acute to the chronic stage after stroke (2011, positive): “According to previous connectivity studies (Grefkes et al., 2008b; Wang et al., 2010), we hypothesized that promoting influences of premotor areas onto ipsilesional M1 might be critically reduced in patients with severe motor impairments in the acute stage after stroke.”
Subregions of the human superior frontal gyrus and their connections (2013, positive): “These findings are consistent with previous observations (Eickhoff et al., 2010) and suggest that a very weak anatomical connection between two regions may still hold a high functional significance (Friston, 2002; Grefkes et al., 2008).”
Is the ADHD brain wired differently? A review on structural and functional connectivity in attention deficit hyperactivity disorder (2010, background): “…either consist of a single area or, e.g., involve cascades of several intermediate areas or cortical-subcortical loops [Eickhoff et al., 2009b; Grefkes et al., 2008]; (ii) A third area could project (directly) to two regions, inducing a correlation of functional activation between them…”
