Document Summary
The right hemisphere plays a role in the more subtle, figurative aspects of speech. The fact that people with transcortical sensory aphasia can repeat words that they cannot understand suggests that there is a direct connection between wernicke"s area and broca"s area. The meanings of words are our memories of objects, actions, and other concepts associated with them. These meanings are memories and are stored in the association cortex, not in the speech areas themselves: anomic aphasia, caused by damage to the temporal or parietal lobes, consists of difficulty in word finding, particularly in naming objects. Brain damage can also disrupt the definitions as well as the. entries in the mental dictionary; damage to specific regions of the association cortex effectively erases some categories of the meanings of words. Damage to broca"s area and surrounding regions disrupts the ability to name actions to think of appropriate verbs.
