Novel Methods for the Visualization and Analysis of Functional Maps in Cortex

Introduction to mrFindBorders 48 Figure 21 shows the specified points as well as atlases that were created based on the three points and other settings, e.g., in the options menu (see section 4.9.2.1). Alternatively, the user can specify a polygon with four points (Figure 22 left). Based on the polygon, the initially aligned atlases are created. They look similar as the ones in Figure 21. The visual-area ROIs (based on atlas annotations) can then be overlaid onto the measured phase image (Figure 22 right). The created atlas images (Figure 21) can be displayed by selecting from the list boxes above the two images in the main window (see section 4.7). Pt. 1 Pt. 2 Pt. 3 Pt. 4 Figure 22: Creation of initial atlas by polygon specification Instead of marking a total of three points in the fovea and in boundaries, the user can draw a polygon by specifying four points (left image). The right image can be displayed when the atlases have been created based on the entered points. It shows visual-area ROIs overlaid onto the measured phase-wedge image.
