Mapping the Human Cortical
(2013) Mapping the human cortical surface by combining quantitative T1 with Retinotopy. We combined quantitative relaxation rate (R 1 = 1/T 1) mapping—to measure local myelination—with fMRI-based retinotopy. Gray– white and pial surfaces were reconstructed and used to sample R 1 at different cortical depths. Like myelination, R 1 decreased from deeper to superficial layers. R 1 decreased passin...

متن کاملCortical surface segmentation and mapping.
Segmentation and mapping of the human cerebral cortex from magnetic resonance (MR) images plays an important role in neuroscience and medicine. This paper describes a comprehensive approach for cortical reconstruction, flattening, and sulcal segmentation. Robustness to imaging artifacts and anatomical consistency are key achievements in an overall approach that is nearly fully automatic and com...

this study was an attempt to investigate and compare the effect of lexical inferencing and concept mapping on developing vocabulary retention of iranian language learners. sixty homogeneous students from different intact classes who were being taught as intermediate learners in sokhan english institute participated in this study. they were in different classes. a teacher made test as a pre-test...
Mapping the cortical representation of the lumbar paravertebral muscles.
OBJECTIVE The aim of this study was to map the cortical representation of the lumbar spine paravertebral (LP) muscles in healthy subjects. METHODS Transcranial magnetic stimulation (TMS) was employed to map the cortical representations of the LP muscles at two sites. Stimuli were applied to points on a grid representing scalp positions. The amplitude of motor evoked potentials (n=6) was avera...
