|---|---|---|---|---|---|
| lesion | tissue destruction. a brain lesion is a naturally or experimentally caused destruction of brain tissue.
🗑
|
||||
| electroencephalogram (EEG) | an amplified recording of the waves of electrical activity sweeping across the brain's surface. these waves are measured by electrodes placed on the scalp.
🗑
|
||||
| PET (positron emission tomography) scan | a visual display of brain activity sweeping across the brain's surface. these waves are measured by electrodes placed on the scalp.
🗑
|
||||
| MRI (magnetic resonance imaging) | a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. These scans show brain anatomy.
🗑
|
||||
| fMRI (functional MRI) | a technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans. these scans show brain function and structure.
🗑
|
||||
| brainstem | the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; it's responsible for automatic survival functions.
🗑
|
||||
| medulla | the base of the brainstem; controls heartbeat and breathing
🗑
|
||||
| thalamus | the brains' sensory control sensory control center, 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.
🗑
|
||||
| reticular formation | a nerve network that travels through the brainstem into the thalamus and plays an important role in controlling arousal.
🗑
|
||||
| cerebellum | the "little brain" at the rear of the brainstem; functions include processing sensory input, coordinating movement output and balance, and enabling nonverbal learning and memory
🗑
|
||||
| limbic system | neural system located below the cerebral hemisphere; associated with emotions and drives.
🗑
|
||||
| hippocampus | a neural center located in the limbic system; helps process explicit memories for storage.
🗑
|
||||
| amygdala | two lime bean-sized neural clusters in the limbic system; linked to emotion
🗑
|
||||
| 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 its linked to emotion and reward.
🗑
|
||||
| cerebral cortex | the intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body's ultimate control and information-processing center.
🗑
|
||||
| frontal lobes | portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgement.
🗑
|
||||
| parietal lobes | 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 | portion of the cerebral cortex lying at the back of the head; included areas that receives information from the visual fields.
🗑
|
||||
| temporal lobes | portion of the cerebral cortex lying roughly above the ears; includes the auditory ares, each receiving the primarily from the opposite ear.
🗑
|
||||
| motor cortex | an area at the rear of the frontal lobes that controls voluntary movements.
🗑
|
||||
| somatosensory cortex | area at the front of the parietal lobes that registers and processes body touch and movement sensations.
🗑
|
||||
| associating 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
🗑
|
||||
| corpus callosum | the large band of neural fibers connecting the two brains hemispheres and carrying messages between them.
🗑
|
||||
| split brain | a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
