Added a clarification that the cases of speech production in both hemispheres occur in split-brain patients, while also correcting grammar and punctuation for clarity and accuracy. |
Added a clarification that the cases of speech production in both hemispheres occur in split-brain patients, while also correcting grammar and punctuation for clarity and accuracy. The clarification comes from the book that is a direct reference to the edited text. Here is an excerpt from the book, from its page 162: "Nonetheless, in a handful of documented cases, splitbrain patients can produce spee ch from both the left and the right hemispheres." |

Line 18:
The permitted organization of words, called [[grammar]], is lateralized in only one hemisphere, typically the left one. These functions include "understanding verbs, pluralizations, the possessive, and active-passive differences" and understanding changes in meaning due to word order.<ref name=":2" /> However, the right hemisphere is able to judge when a sentence is grammatically correct, which may indicate that patterns of speech are learned by rote rather than applied through understanding rules.<ref name=":2" />
[[Speech]] production and language comprehension are specialized in [[Broca's area|Broca's]] and [[Wernicke's area|Wernicke's]] areas respectively, which are located in the left hemisphere for 96% of right-handers and 70% of left-handers.<ref name=":2" /><ref name="Griggs2012">{{cite book |title=Psychology : a concise introduction |vauthors=Griggs RA |date=2012 |publisher=Worth Publishers |isbn=978-1429261555 |edition=3rd |___location=New York, NY}}</ref> However, there
In [[writing]], studies attempting to isolate the linguistic component of written language in terms of brain lateralization could not provide enough evidence of a difference in the relative activation of the brain hemispheres between left-handed and right-handed adults.<ref>{{cite journal | vauthors = Papadopoulou AK, Samsouris C, Vlachos F, Badcock N, Phylactou P, Papadatou-Pastou | title = Exploring cerebral laterality of writing and the relationship to handedness: a functional transcranial Doppler ultrasound investigation | journal = Laterality | volume = 29 | issue = 1 | pages = 117–150 | date = November 2023 | doi = 10.1080/1357650X.2023.2284407| pmid = 38112692 }}</ref>
