Journal ArticleDOI
The circumplex model of affect: an integrative approach to affective neuroscience, cognitive development, and psychopathology
TL;DR: It is proposed that basic emotion theories no longer explain adequately the vast number of empirical observations from studies in affective neuroscience, and it is suggested that a conceptual shift is needed in the empirical approaches taken to the study of emotion and affective psychopathologies.
Journal ArticleDOI
Atypical Default Network Connectivity in Youth with Attention-Deficit/Hyperactivity Disorder
Damien A. Fair,Jonathan Posner,Bonnie J. Nagel,Deepti R. Bathula,Taciana G. Costa Dias,Kathryn L. Mills,Michael S. Blythe,Aishat Giwa,Colleen F. Schmitt,Joel T. Nigg +9 more
TL;DR: Functional connections previously shown as developmentally dynamic in the default network were atypical in children with attention deficit/hyperactivity disorder-consistent with perturbation or failure of the maturational processes.
Journal ArticleDOI
Neural Systems Subserving Valence and Arousal During the Experience of Induced Emotions
Tiziano Colibazzi,Jonathan Posner,Zhishun Wang,Daniel Gorman,Andrew J. Gerber,Shan Yu,Hongtu Zhu,Alayar Kangarlu,Yunsuo Duan,James A. Russell,Bradley S. Peterson +10 more
TL;DR: These findings suggest the existence of distinct networks subserving the valence and arousal dimensions of emotions, with midline and medial temporal lobe structures mediating arousal and dorsal cortical areas and mesolimbic pathways mediating valence.
Journal ArticleDOI
Antidepressants Normalize the Default Mode Network in Patients With Dysthymia
Jonathan Posner,David J. Hellerstein,Inbal Gat,Anna Mechling,Kristin Klahr,Zhishun Wang,Patrick J. McGrath,Jonathan W. Stewart,Bradley S. Peterson +8 more
TL;DR: The baseline imaging findings are consistent with those found in patients with major depressive disorder and suggest that increased connectivity within the DMN may be important in the pathophysiology of both acute and chronic manifestations of depressive illness.
Journal ArticleDOI
Connecting the Dots: A Review of Resting Connectivity MRI Studies in Attention-Deficit/Hyperactivity Disorder
TL;DR: Findings from extant rs-fcMRI studies of ADHD focusing on neural circuits implicated in the disorder, especially the default mode network, cognitive control network, and cortico-striato-thalamo-cortical loops are reviewed.
