Downloading mricron 1.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Education Tools, more precisely Science. This free Mac app is an intellectual property of NITRC. The most popular version among the application users is 1.0. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
You can get a similar view by launching the software, choosing File/OpenTemplates/ch2bet to load the background image (shown as a grayscale brain) and then choosing Overlay/Add and opening the image \Template\attention. The controls on the tool bar offer quick access to the main tools for brain imaging. The X/Y/Z numbers set the slice to view (X refers to Left/Right, Y to anterior/posterior and Z to superior/inferior).
