Brain asymmetry
From Wikipedia, the free encyclopedia
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.[1]
