26 Cards in this Set

  • Front
  • Back
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)
