Brain Asymmetry

In human neuroanatomy brain asymmetry can refer to at least two quite distinct findings:

  • Neuroanatomical differences between the left and right sides of the brain
  • Lateralized functional differences: Lateralization of brain function

Neuroanatomical differences themselves exist on different scales, from neuronal densities, to the size of regions such as the planum temporale, to—at the largest scale—the torsion or "wind" in the human brain, reflected shape of the skull, which reflects a backward (posterior) protrusion of the left occipital bone and a forward (anterior) protrusion of the right frontal bone.

Famous quotes containing the word brain:

    Progress celebrates Pyrrhic victories over nature. Progress makes purses out of human skin. When people were traveling in mail coaches, the world got ahead better than it does now that salesmen fly through the air. What good is speed if the brain has oozed out on the way? How will the heirs of this age be taught the most basic motions that are necessary to activate the most complicated machines? Nature can rely on progress; it will avenge it for the outrage it has perpetrated on it.
    Karl Kraus (1874–1936)
