Lesion
tissue destruction
Electroencephalogram (EEG)
an amplified recording of the waves of electrical signals that sweep across the brains surface.
(CT) computed tomography scan
a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body.
PET (position emission tomography) scan
a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
MRI magnetic resonance imaging
a technique that uses magnetic fields and radio waves to produce computergenerated images that estinguish among differnt types of soft tissue; allows us to see structures within the brain
Brainstem
the oldest part and central part 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 heartbeat and breathing
Reticular formation
a nerve network in brainstem that plays an important role and controlling arousal
Thalamus
the brains sensory switchboard, located at the top of the brainstem; it directs messages to sensory recieving areas in the cortex and transmits replies to the cerebellum and the medulla
Cerebellum
the little brain attached to the rear of the brainstem it helps cordinate voluntery movement and balance
Limbic system
system of neural structures at the border of the brainstem and cerebral hemispheres; associated with emotions such as fear and agression and drives such as those of food and sex. Includes the hippocampus, amygala, and hypothalamus
amygdala
two almond-shaped neural clusters that are components of the limpic system an are linked to emotion
hypothalamus
a neural structure lying below the thalamus; directs eating drinking body temperature, helps govern endocrine system, via pituitary gland
cerebral cortex
the indicate fabric of interconnected neural cells that covers the cerbral hemispheres; the boy's ultimate control and information-proccesing center
glial cells
cells in the nervous system that support nourish and protect neurons
frontal lobes
just behind e forhead; involved in speaking and muscle movements; in making plans and judgements
parietal lobes
the portion of the cerebral cortex lying at the top of the head and towards the rear; includes a sensory cortex
occipital lobes
lying at the back of the head; includes the visual areas, which recieve visual information from the opposite visual fields
temporal lobes
above the ears, includes auditory areas, each of which recieves auditory information primarily from the opposite ear.
motor cortex
at the rear frontal lobes that controls voluntery movement
sensory cortex
the area at the front of the parietal lobes that registers and processes body sensations
association areas
involved in higher mental functions such as learning, remembering, thinking and speaking
aphasia
impairment of language
broca's area
controls language expression
wernicke's area
contrlos language reception
plasticity
the brains capacity for motification
corpus collasum
large band of neural fibers connecting the two brain hemispheres and carying messages between them
split brain
conition in which the two hemispheres of the brain are isolated by cutting the connecting fibers between them
endocrine system
the body's slow chemical communication system; a set of glands that secrete hormones into the bloodstream
hormones
chemical messages,mostly those manufactured by the endocrine glands
adrenal glands
a pair of endocrine glans just above the kidneys. the adrenals secrete the hormones epinephrine and nonepinephrine which help arouse the body
pituitary gland
the endocrine systems most influencial gland, regulates growth and controls endocrine glands
