Journal ArticleDOI
A new SPM toolbox for combining probabilistic cytoarchitectonic maps and functional imaging data
Simon B. Eickhoff,Klaas E. Stephan,Hartmut Mohlberg,Christian Grefkes,Gereon R. Fink,Katrin Amunts,Karl Zilles +6 more
TL;DR: A new, MATLAB based toolbox for the SPM2 software package is introduced which enables the integration of probabilistic cytoarchitectonic maps and results of functional imaging studies and an easy-to-use tool for the integrated analysis of functional and anatomical data in a common reference space.
Journal ArticleDOI
Coordinate-based activation likelihood estimation meta-analysis of neuroimaging data: a random-effects approach based on empirical estimates of spatial uncertainty
TL;DR: The authors showed that the revised ALE‐algorithm overcomes conceptual problems of former meta‐analyses and increases the specificity of the ensuing results without loosing the sensitivity of the original approach, and may provide a methodologically improved tool for coordinate‐based meta-analyses on functional imaging data.
Journal ArticleDOI
Evidence-based guidelines on the therapeutic use of repetitive transcranial magnetic stimulation (rTMS): An update (2014–2018)
Jean Pascal Lefaucheur,André Aleman,Chris Baeken,David H. Benninger,Jerome Brunelin,Vincenzo Di Lazzaro,Saša R. Filipović,Christian Grefkes,Alkomiet Hasan,Friedhelm C. Hummel,Satu K. Jääskeläinen,Berthold Langguth,Letizia Leocani,Alain Londero,Raffaele Nardone,Jean-Paul Nguyen,Thomas Nyffeler,Albino J. Oliveira-Maia,A. Oliviero,Frank Padberg,Ulrich Palm,Walter Paulus,Emmanuel Poulet,Angelo Quartarone,Fady Rachid,Irena Rektorová,Simone Rossi,Hanna Sahlsten,Martin Schecklmann,David Szekely,Ulf Ziemann +30 more
TL;DR: These updated recommendations take into account all rTMS publications, including data prior to 2014, as well as currently reviewed literature until the end of 2018, and are based on the differences reached in therapeutic efficacy of real vs. sham rT MS protocols.
Journal ArticleDOI
The functional organization of the intraparietal sulcus in humans and monkeys.
Christian Grefkes,Gereon R. Fink +1 more
TL;DR: In macaque monkeys, the posterior parietal cortex (PPC) is concerned with the integration of multimodal information for constructing a spatial representation of the external world (in relation to the macaque's body or parts thereof), and planning and executing object-centred movements as mentioned in this paper.
Journal ArticleDOI
Cortical connectivity after subcortical stroke assessed with functional magnetic resonance imaging
Christian Grefkes,Dennis A. Nowak,Simon B. Eickhoff,Manuel Dafotakis,Jutta Küst,Hans Karbe,Gereon R. Fink +6 more
TL;DR: This study aimed at identifying the impact of subcortical stroke on the interaction of cortical motor areas within and across hemispheres during the generation of voluntary hand movements.
