The person using a verbal strategy, by contrast, will exhibit higher levels of activity in the left-hemisphere speech processing centers such as Wemicke's and Broca's areas.
Verbalization will, in almost all right-handed subjects, be associated with increased activity in the left-hemisphere speech processing centers such as Wernicke's and Broca's areas. Furthermore, verbalization that is not behaviorally apparent, that is, sub-vocalization, will also be associated with increased activity at speech processing sites.
