Terms : Hide Images
| 226305873 | Electroencephalogram | an amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp. | |
| 226305874 | CT Scan | a 3-D image of the brain | |
| 226305875 | Corpus Callosum | the large band of neural fibers connecting the two brain hemispheres and carryiing messages between them | |
| 226305876 | Cerebral Cortex | the intricate fabric of interconnected neural cells that covers the cerebral hemispheres; the body's ultimate control and information-processing center | |
| 226305877 | Cerebellum | the "little brain" attached to the rear of the brainstem; its functions include processing sensory input and coordinating movement output and balance | |
| 226305878 | Broca's area | controls language expression - an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech | |
| 226305879 | Brainstem | the oldest part and cetral core of the brain, beginning where the spinal cord swells as it enters the skull; it is responsible for automatic survival functions | |
| 226305880 | Wernicke's area | controls language reception - a brain area involved in language comprehension and expression; usually in the left temporal lobe | |
| 226305881 | Thalamus | the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla | |
| 226305882 | Temporal lobes | the portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each of which receives auditory information primarily from the opposite ear | |
| 226305883 | Split brain | a condition in which the two hemispheres of the brain are isolated by cutting the connecting fibers (mainly those of the corpus callosum) between them | |
| 226305884 | Sensory cortex | the area at the front of parietal lobes that registers and processes body touch and movement sensations | |
| 226305885 | Reticular formation | a nerve network in the brainstem that plays an important role in controlling arousal | |
| 226305886 | Plasticity | the brain's capacity for modification, as evident in brain reorganization following damage (especially in children) and in experiments on the effects of experience on brain development | |
| 226305887 | PET scan | a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task | |
| 226305888 | Parietal 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 | |
| 226305889 | Occipital lobes | the portion of the cerebral cortex lying at the back of the head; includes the visual areas, which receive visual information from the opposite visual field | |
| 226305890 | MRI | a technique for revealing blood flow and, therefore, brain activity by comparing successive scans. It shows brain anatomy, f[blank] scans show brain function | |
| 226305891 | Association areas | areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental funcitons such as learning, remembering, thinking and speaking | |
| 226305892 | Motor cortex | an area at the rear of the frontal lobes that controls voluntary movements | |
| 226305893 | Medulla | the base of the brainstem, controls heartbeat and breathing | |
| 226305894 | Limbic system | a donut-shaped system of neural strutures at the border of the brainstem and cerebral hemispheres; associated with emtions such as fear and aggression and drives such as those for food and sex. Includes the hippocampus, amygdala, and hypothalamus. | |
| 226305895 | Lesion | tissue destruction. a brain [blank] is a naturally or experimentally caused destruction of brain tissue | |
| 226305896 | Hypothalamus | a neural structure lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion | |
| 226305897 | Glial cells | cells in the neural system that support, nourish and protect neurons | |
| 226305898 | Frontal lobes | the portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgements | |
| 226305899 | Aphasia | impairment of language, usually caused by left hemisphere damage either to Broca's area (impairing speaking) or to Wenicke's area (impairing understanding) | |
| 226305900 | Amygdala | two lima bean-sized neural clusters that are components of the limbic system and are linked to emotion |
