....resolution of the fMRI signal. Fig. 5B shows a real measurement of the angular retinotopic map on a flattened representation of the region near calcarine cortex. Such flat maps of visual cortex are used to make it easier to see the representation along extended regions of the cortical brain [62 64]; otherwise, it is difficult to visualize data that fall at the bottom of sulci. The rotating wedge stimulus is important for measuring the boundaries between retinotopically organized visual areas, but to be certain that one has identified a well grouped area, both dimensions of retinotopic ....

....Brain researchers, neurologists and neurosurgeons acquire 3D brain images from normal and diseased subjects with the idea to study the properties of brains, make comparisons and to measure changes caused by factors like age and disease. Over the last few years, significant e#orts have been made [1, 2, 3, 4] to create software to extract the cerebral cortex (or other structures) from the brain, and reconstruct it as a 3D digital object for further analysis. While they all use di#erent techniques to derive the digital representation of the structure, they all represent it as some form of a surface ....
