Question 2: What does the following picture show?

  Visualization of a diffusion tensor imaging (DTI) measurement of a human brain. Depicted are reconstructed axon tracts that run through the mid-sagittal plane. Especially prominent are the U-shaped fibers that connect the two hemispheres through the corpus callosum (the fibers come out of the image plane and consequently bend towards the top) and the fiber tracts that descend toward the spine (blue, within the image plane).
  Topography of the primary motor cortex, showing which body part is controlled by each zone
  The corpus callosum, a nerve bundle connecting the two cerebral hemispheres, with the lateral ventricles directly below
  Computed tomography of human brain, from base of the skull to top, taken with intravenous contrast medium
