Physiological Mapping of Human Auditory Cortices with a Silent Event-Related fMRI Technique
Autor: Jessica Zonana, Almut Engelien, Yihong Yang, Emily Stern, David Silbersweig, Wolfgang Engelien
Publikováno v: NeuroImage. 16:944-953
Cortical field boundaries of sensory areas can be physiologically defined. The delineation of the human auditory cortical architecture remains incomplete. Here we used systematic variation of pitch and duration of sinusoidal tones to define auditory

Mapping Transient, Randomly Occurring Neuropsychological Events Using Independent Component Analysis
Autor: David Silbersweig, Wolfgang Engelien, Emily Stern, Hanhua Feng, Hong Gu, Yihong Yang
Publikováno v: NeuroImage. 14:1432-1443
The feasibility of mapping transient, randomly occurring neuropsychological events using independent component analysis (ICA) was evaluated in an auditory sentence-monitoring fMRI experiment, in which prerecorded short sentences of random content wer

Differential time courses and specificity of amygdala activity in posttraumatic stress disorder subjects and normal control subjects
Autor: Marylene Cloitre, Joseph E. LeDoux, David Silbersweig, Emily Stern, Xenia Protopopescu, Jack M. Gorman, Oliver Tuescher, Martin Goldstein, Jane Epstein, Hong Pan, Wolfgang Engelien, Yihong Yang
Publikováno v: Biological psychiatry. 57(5)
Background Previous neuroimaging studies have demonstrated exaggerated amygdala responses to negative stimuli in posttraumatic stress disorder (PTSD). The time course of this amygdala response is largely unstudied and is relevant to questions of habi

A CBF-based event-related brain activation paradigm: characterization of impulse-response function and comparison to BOLD
Autor: Wolfgang Engelien, Emily Stern, Su Xu, Hong Pan, David Silbersweig, Yihong Yang
Publikováno v: NeuroImage. 12(3)
A perfusion-based event-related functional MRI method for the study of brain activation is presented. In this method, cerebral blood flow (CBF) was measured using a recently developed multislice arterial spin-labeling (ASL) perfusion imaging method w

A silent event-related functional MRI technique for brain activation studies without interference of scanner acoustic noise
Autor: Su Xu, Almut Engelien, Emily Stern, David Silbersweig, Wolfgang Engelien, Yihong Yang
Publikováno v: Magnetic resonance in medicine. 43(2)
A new data acquisition method for silent, event-related functional MRI in which scanner acoustic noise does not interfere with brain activation is introduced and evaluated in an auditory tonotopic mapping experiment. This method takes into account th
