Webby using fMRI. On the basis of previous studies, it was hypothesized that responsive naming would produce temporal activation to a greater extent and would more often include activation of anterior temporal regions than confrontation naming. Methods Participants. Participants in this study included 20 healthy right-handers. WebUsing fMRI, brain activation was measured in 10 third- and 10 sixth-grade school children and 20 adults during trials of symbolic approximate (AP) and exact (EX) calculation, as well as non-symbolic magnitude comparison (MC) of objects. brother justio fax-2840 説明書

WebBackground: Blood oxygen level-dependent (BOLD) functional MRI (fMRI) has been widely applied to detect brain activations. Recent advances in multiband (MB) and multiecho (ME) techniques have greatly improved fMRI methods. MB imaging improves temporal and/or spatial resolution, while ME imaging has been shown to improve BOLD sensitivity. WebActivation Maps The image shown is the result of the simplest kind of FMRI experiment. While lying in the MRI scanner the subject watched a screen which alternated between showing a visual stimulus and being dark every 30 second. Meanwhile the MRI scanner tracked the signal throughout the brain. WebEvent-related functional magnetic resonance imaging revealed hippocampal activity that differentiates novel from repeated arrays. This pattern of results was observed without recognition of the repeating arrays. ... Consistent with our predictions, we found hemodynamic activation in the hippocampal ROIs that were differentially sensitive to ... brother justice mn
