| 4888929500 | Occipital Lobes | 1) portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields 2) part of brain at the back, controls vision |  | 18 |
| 4888932141 | Temporal Lobes | 1) portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear. 2) located at the sides, controls hearing |  | 19 |

| 4888943054 | Association Areas | 1) areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking. 2) areas of thinking |  | 22 |
| 4888946487 | Aphasia | 1) impairment of language, usually caused by left hemisphere damage either to Broca's area (impairing speaking) or to Wernicke's area (impairing understanding) 2) language damage | 23 | |
