Brain Fissure Development

Three-dimensional reconstruction of the lateral (top row) and medial (bottom row) surface of 13–21 week brains to reveal the development of the Sylvian fissure (green arrow), the calcarine fissure (blue arrow), and the parieto-occipital sulcus (red arrow), respectively.

  • the terms fissure and sulcus refer to the same feature.
  • Sylvian fissure (sulcus) is also called the lateral fissure (sulcus).


Diffusion tensor imaging (DTI) A newly developed form of magnetic resonance imaging (MRI). Magnetic field variations of the MRI magnet are applied in at least six different directions generating a three dimensional shape of the diffusion pattern. This technique can be used in neural imaging of white matter due to the orientation of axon bundles and the associated water flow. (More? Magnetic Resonance Imaging)
