UNIT 2 The Cerebral Cortex
Term | Definition |
---|---|
Frontal Lobes | the portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgments. |
Partial Lobes | the portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position. |
Occipital Lobes | the portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields. |
Temporal Lobes | the portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear. |
Motor Cortex | an area at the rear of the frontal lobes that controls voluntary movements. |
Somatosensory Cortex | an area at the front of the parietal lobes that registers and processes body touch and movement sensations. |
Association Areas | 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. |
Plasticity | the brain's ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience. |
neurogenesis | the formation of new neurons |
