|
lesion |
tissue destruction. A brain lesion is a naturally or experimentally caused destruction of brain tissue |
|
|
electroenecephalogram (EEG) |
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 |
|
|
PET (positron emission tomography) scan |
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 |
|
|
MRI |
a technique that uses magnetic fields and radio waves to produce computer generated images of soft tissue. show brain anatomy |
|
|
fMRI (functional MRI) |
a technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI sans. show brain function |
|
|
brainstem |
the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; responsible for automatic survival functions |
|
|
medulla |
the base of the brainstem; controls heartbeat and breathing |
|
|
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 |
|
|
reticular formation |
a nerve network that travels through the brainstem and plays and important role in controlling arousal |
|
|
cerebellum |
the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance |
|
|
limbic system |
neural system located below cerebral hemisphere; 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;directs several maintenance activities (eating, drinking) helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward. |
