Journal ArticleDOI
Spatiotemporal analysis of brain electrical fields
TL;DR: It is proposed that an important first step for functional studies is to examine accurate, time‐dynamic maps of the brain's electrical fields at the head surface, given an adequate spatial sampling of the surface potentials.
Journal ArticleDOI
The somatotopy of speech: Phonation and articulation in the human motor cortex
Steven Brown,Angela R. Laird,Peter Q. Pfordresher,Sarah M. Thelen,Peter E. Turkeltaub,Mario Liotti +5 more
TL;DR: Functional magnetic resonance imaging was used to compare an overt speech task with tongue movement, lip movement, and vowel phonation and showed that the strongest motor activation for speech was the somatotopic larynx area of the motor cortex, thus reflecting the significant contribution of phonation to speech production.
Journal ArticleDOI
Semantic amnesia with preservation of autobiographic memory. A case report.
TL;DR: A 44-year-old woman showed, following an episode of encephalitis, an impoverished knowledge of the meaning and attributes of words and their referents, in spite of intact command of grammatical-syntactic rules and preserved perceptual abilities.
Journal ArticleDOI
Hypophonia in Parkinson’s disease Neural correlates of voice treatment revealed by PET
Mario Liotti,Lorraine Olson Ramig,Deanie Vogel,P. Z. New,C. I. Cook,Roger J. Ingham,Janis C. Ingham,Peter T. Fox +7 more
TL;DR: Effective improvement of IPD hypophonia following voice treatment with VT was accompanied by a reduction of cortical motor–premotor activations, resembling the functional pattern observed in healthy volunteers and suggesting normalization, and additional recruitment of right anterior insula, caudate head, putamen, and DLPFC.
Journal ArticleDOI
Neuroimaging of cerebral activations and deactivations associated with hypercapnia and hunger for air
Stephen K. Brannan,Mario Liotti,Gary F. Egan,Robert E. Shade,Lisa Madden,Rachel Robillard,Bart Abplanalp,Katie Stofer,Derek A. Denton,Peter T. Fox +9 more
TL;DR: The striking response of limbic and paralimbic regions points to these structures having a singular role in the affective sequelae entrained by disturbance of basic respiratory control whereby a process of which the authors are normally unaware becomes a salient element of consciousness.
