To study the brain are often used images that allow you to see its outer surface (cortex) or distinct parts which are inside (agmídala, brain…)
Sagittal sections normally used to represent the inside while, Thanks to modern techniques of representation, can simulate cortex transparent walls which allow observation of the elements normally hidden. The picture is a representation of the cortex with the technique of creating “halo” Blender itself, as an alternative models estos.
