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:
“When the situation is, what we would wish, nothing is so ill- timed as to hint at the circumstances which make it so: you thank Fortune ... you had reason—the heart knew it, and was satisfied; and who but an English philosopher would have sent notices of it to the brain to reverse the judgment?”
—Laurence Sterne (1713–1768)
