brainstem
|
begins where the spinal cord swells as it enters the skull: responsible for automatic survivalo functions
|
|
medulla
|
base of the brainstem controls life support functions like heartbeat and breathing
|
|
retiular formation
|
a nerve network in the brainstem that plays an important role in controlling wakefulness and arousal
|
|
thalamus
|
the brain's sensory switchboard on top of brainstem directs messages to the sensory receiving areas in the cortex
|
|
cerebellum
|
little brain attached to the rear of the brainstem help coordinate voluntary movements and balance
|
|
case study
|
one person is studied in depth in hope of revealing universal principles
|
|
computerized axial tomography
|
CAT scan series of x rays taken from different angles and combined by computer into a composite representation of a slice through the body
|
|
magnetic resonance imaging
MRI |
uses magnetic fields and radio waves to produce computer- generated images that distinguish's among different types of soft tissue allows us to see structure within the brain
|
|
electroencephalogram
EEG |
an amplified recording of the waves of electrical activity that sweep across the brain's surface measured by electrodes placed on the scalp and used to evaluvate brain function
|
|
Position Emission Tomography
PET Scan |
visual display of brain activity that detects where a radioactive form of glucose goes while the brain function
|
|
limbic system
|
a ring of structures at the border of the brainstem and cerebral cortex helps regulate memory fear aggression, hunger,and thirst includes hypothalamus hippocampus and amygdala
|
|
hypothalamos
|
below the thalamus directs eating and drinking and body temp an is linked to emotion
|
|
hippocampus
|
in the limbic system helps process new memories for permanent storage
|
|
amygdala
|
two almond shaped neural clusters in the limbic system that are linked to emotions such as fear and anger
|
|
cerebral cortex
|
form the cerebral hemispheres the body's ultimate controland information processing center
|
|
longitudinal fissure
|
the long crack running from the front to the vack of the cerebral cortex separates right and left hemispheres
|
|
corpus callosum
|
large band of nevral fibers that connects the two brain hemispheres and carreis messages between them
|
|
frontal lobes
|
portion of the cerebral cortex just behind the forehead includes motor cortex involved in making plans and judgements
|
|
parietel lobes
|
porttion of the cerebral cortex at the top of your head toward the rear includes the somatosensory cortex & general association areas used for processing info
|
|
occipital lobes
|
portion of the cerebral cortex at the back of your head includes visual processing areas
|
|
temporal lobes
|
portion of the cerebral cortex just above the ears includes auditory areas
|
|
motor cortex
|
a brain area at the rear of the frontal lobes that controls voluntary movements
|
|
somatosensory
|
in front of the parietal lobes and registers and processes body sentations
|
|
Broca's area
|
part of the frontal lobe (usually in the left hemisphere ) that directs the muscle movements involved in speech
|
|
Wernicke's area
|
brain area involved in language comprhension and expression usually in the left temporal lobe
|
|
plasticity
|
the brain's capacity for modification as evident in brain reorganization following damage (especiallly in Kids)
|
