Journal ArticleDOI
Conn: A Functional Connectivity Toolbox for Correlated and Anticorrelated Brain Networks
TL;DR: The results indicate that the CompCor method increases the sensitivity and selectivity of fcMRI analysis, and show a high degree of interscan reliability for many fc MRI measures.
Journal ArticleDOI
Hyperactivity and hyperconnectivity of the default network in schizophrenia and in first-degree relatives of persons with schizophrenia
Susan Whitfield-Gabrieli,Heidi W. Thermenos,Snezana Milanovic,Ming T. Tsuang,Stephen V. Faraone,Robert W. McCarley,Martha E. Shenton,Alan I. Green,Alfonso Nieto-Castanon,Peter S. LaViolette,Joanne Wojcik,John D. E. Gabrieli,Larry J. Seidman +12 more
TL;DR: Among patients, the magnitude of MPFC task suppression negatively correlated with default connectivity, suggesting an association between the hyperactivation and hyperconnectivity in schizophrenia.
Journal ArticleDOI
New Method for fMRI Investigations of Language: Defining ROIs Functionally in Individual Subjects
Evelina Fedorenko,Po-Jang Hsieh,Alfonso Nieto-Castanon,Susan Whitfield-Gabrieli,Nancy Kanwisher +4 more
TL;DR: The selectivity of these regions is stronger using the method than when standard group analyses are conducted on the same data, suggesting that the future application of this method may reveal clearer functional specificity than has been evident in prior neuroimaging research on language.
Journal ArticleDOI
Associations and dissociations between default and self-reference networks in the human brain.
Susan Whitfield-Gabrieli,Joseph M. Moran,Alfonso Nieto-Castanon,Christina Triantafyllou,Rebecca Saxe,John D. E. Gabrieli +5 more
TL;DR: These findings indicate that there are both associations (shared components) and dissociations between the neural systems underlying explicit self-reference and the default mode of brain function.
Journal ArticleDOI
A Wireless Brain-Machine Interface for Real-Time Speech Synthesis
Frank H. Guenther,Frank H. Guenther,Jonathan S. Brumberg,E. Joseph Wright,Alfonso Nieto-Castanon,Jason A. Tourville,Mikhail Panko,Robert Law,Steven A. Siebert,Jess Bartels,Dinal Andreasen,Princewill Ehirim,Hui Mao,Philip R. Kennedy +13 more
TL;DR: The results support the feasibility of neural prostheses that may have the potential to provide near-conversational synthetic speech output for individuals with severely impaired speech motor control.
