|---|---|---|---|---|---|
| Lesion | tissue destruction. A brain lesion is a naturally or experimentally destruction of brain tissue
🗑
|
||||
| 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
🗑
|
||||
| MEG | a brain imaging technique that measures magnetic fields from the brain's natural electrical activity
🗑
|
||||
| CT scan | a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brain's structure (also called CAT scan)
🗑
|
||||
| Pet scan | a visual display of visual activity that detects where a radioactive form of glucose goes while the brain performs a given task
🗑
|
||||
| MRI | a technique that uses magnetic fields and radio waves to produce computer generated images of soft tissue. MRI scans show brain anatomy
🗑
|
||||
| fMRI | a technique fro revealing bloodflow and, therefore, brain activity by comparing successive MRI scans. fMRI scans show brain function as well as structure.
🗑
|
||||
| Brainstem | the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; the brainstem is responsible for automatic survival functions
🗑
|
||||
| Medulla | the base of the brainstem; controls heatbeat and breathing
🗑
|
||||
| Thalamus | the brain's sensory control center, located on top of the brainstem; it directs messages to the sensory and 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 (including the amygdala, hypothalamus, and hippocampus) located below the cerebral hemispheres; associated with emotions and drives
🗑
|
||||
| Amygdala | two lima-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 is linked to emotion and reward
🗑
|
||||
| Hippocampus | a neural center located in the limbic system; helps process for storage explicit (conscious) memories of facts and events
🗑

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.
