You don’t have to be a neurosurgeon to get up close and personal with the human brain. Thanks to the BrainTutor HD app, now anyone can explore and learn about the brain via two types of 3D models: cartoon animations and fMRI imaging stacks. The cartoon models can display either hemisphere alone or both hemispheres combined; the fMRI image stacks can be viewed under the “head” option, with options to scan the stacks through top-down, side-to-side, or front-to-back views. The brain is divided into six atlases: lobes, gyri, sulci, Brodmann areas, subcortical areas, and functional areas. Each atlas contains a number of brain areas that users can individually select to highlight them on the 3D model. In addition, each brain area is accompanied by a description that includes information on nomenclature/parts, location, and function/connectivity.
