Speech—e.g., cochlear implant speech; (2) neural correlates of conceptual representations of action verbs; and (3) design of robust, highly reliable fMRI experimental protocols suitable for longitudinal and clinical studies of speech function. Animal preparation and conditioning protocol. Objective: The purpose of this protocol is three-fold: 1) to develop methods with which we can evoke positive and negative affect and visualize concomitant brain activation, 2) to determine how individual differences in evoked brain responses relate to generalized trait personality and behavior Outcome measures: The outcome measure is differences in blood oxygenation dependent level (BOLD) signal measured using standard fMRI techniques and analyzed using AFNI software. 'Fast fMRI' Protocol Could Aid In Planning Surgery For Epilepsy And Brain Tumors. Functional Magnetic Resonance Imaging (fMRI) is a powerful neuroimaging technique that allows in-vivo imaging of brain function using local changes in blood oxygenation levels (BOLD) as an intrinsic metabolic marker of neural activity. Beatboxer's technique analysed with MRI scanner All of the data was acquired using a realtime MRI protocol developed at USC specifically for studying speech. Diffusion-weighted MR imaging (DWI-MRI) and apparent diffusion coefficient maps have demonstrated their value in improving the accuracy of breast MRI at 1.5 tesla compared to conventional scanning protocols. But do these techniques also work at 3 tesla? Researchers use MRI techniques in humans to image brain characteristics such as anatomy in structural MRI, oxygen consumption in functional MRI (fMRI), and white matter integrity in diffusion tensor imaging (DTI). Animals were subsequently conditioned to a fear-associated cue on day 4 in a separate and distinct context, and were scanned in the real MRI scanner on day 5 (Figure 1).
