Human Cortex Parcellation (IMAGE) NIH/National Institute of Mental Health Caption The researchers discovered that our brain's cortex, or outer mantle, is composed of 180 distinct areas per hemisphere. For example, the image above shows areas connected to the three main senses -- hearing (red), touch (green) vision (blue) and opposing cognitive systems (light and dark). The map is based on data from resting state fMRI scans performed as part of the Human Connectome Project.
