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
The neurophysiological bases of emotion: An fMRI study of the affective circumplex using emotion‐denoting words
Jonathan Posner,James A. Russell,Andrew J. Gerber,Daniel Gorman,Tiziano Colibazzi,Shan Yu,Zhishun Wang,Alayar Kangarlu,Hongtu Zhu,Bradley S. Peterson +9 more
TL;DR: Findings clarify inconsistencies from prior imaging studies of affect by suggesting that two underlying neurophysiological systems, valence and arousal, may subserve the processing of affective stimuli, consistent with the circumplex model of affect.
Journal ArticleDOI
An affective circumplex model of neural systems subserving valence, arousal, and cognitive overlay during the appraisal of emotional faces
Andrew J. Gerber,Jonathan Posner,Daniel Gorman,Tiziano Colibazzi,Shan Yu,Zhishun Wang,Alayar Kangarlu,Hongtu Zhu,James A. Russell,Bradley S. Peterson +9 more
TL;DR: These findings are interpreted as showing that a face rated as having low arousal is more ambiguous and a face rating as having extreme valence is more personally salient, which explains how both low arousal and extremeValence lead to greater activation of an ambiguity/salience system subserved by the amygdala, cerebellum, and dorsal pons.
Journal ArticleDOI
Cognitive, cardiac, and physiological safety studies in ultra high field magnetic resonance imaging.
Alayar Kangarlu,Richard Burgess,Hui Zhu,Tomohiro Nakayama,Robert L. Hamlin,Amir M. Abduljalil,Pierre Marie L. Robitaille +6 more
TL;DR: It is concluded that no short term cardiac or cognitive effects are observed following significant exposure to a magnetic field of up to 8.0 tesla.
Journal ArticleDOI
Human magnetic resonance imaging at 8 T.
Pierre Marie L. Robitaille,Amir M. Abduljalil,Alayar Kangarlu,Xiaoliang Zhang,Ying Yu,Richard Burgess,S. Bair,P. Noa,L. Yang,Hui Zhu,Brian S. Palmer,Zongcheng Jiang,D. M. Chakeres,Dimitri G. Spigos +13 more
TL;DR: The first human magnetic resonance image (MRI) obtained at ultrahigh field strengths (8 T) is presented and it is demonstrated that clinical imaging will be possible at 8 T and that reasonable quality head images can be obtained at this field strength.
