Section 1

Question Answer
magnetic resonance imaging (MRI) and computed tomography (CT)tests to examine the soft tissue structures of the brain and spinal cord
functional MRIdetects changes in blood flow in the brain when the patient is asked to PERFORM A SPECIFIC TASK
carotid ultrasonographyan ultrasound study of the carotid artery
echoencephalographythe use of ULTRASOUND imaging to create a DETAILED VISUAL IMAGE of the brain for diagnostic purposes
electroencephalographythe process of recording the ELECTRICAL ACTIVITY of the brain
myelographya radiographic study of the SPINAL CORD after the injection of a contrast medium through a lumbar puncture
lumbar puncture AKA spinal tapthe process of obtaining a sample of cerebrospinal fluid by inserting a needle into the subarachnoid space of the lumbar region to withdraw fluid

Section 2

Question Answer
hypnoticdepresses the central nervous system and usually produces SLEEP
anticonvulsantadministered to prevent seizures
barbituratesa class of drugs whose major action is a calming or depressed effect on the central nervous system
amobarbitala barbiturate used as a sedative and hypnotic
phenobarbitala barbiturate used as a sedative and an anticonvulsant
sedativedepresses the central nervous system to produce calm and diminished responsiveness WITHOUT producing sleep
anesthesiathe ABSENSE OF normal SENSATION, especially sensitivity to pain; is induced by administration of an anesthetic agent
anestheticthe medication used to induce anesthesia; it may be topical, local, regional or general
epidural anesthesiaregional anesthesia produced by injecting medication into the epidural space of the lumbar or sacral region of the spine
general anesthesiainvolves the TOTAL LOSS of body sensation and consciousness
local anesthesiacauses the loss of sensation in a limited area
regional anesthesiathe temporary interruption of nerve conduction
spinal anesthesiaregional anesthesia produced by injecting medication into the subarachnoid space; provides numbness from the toes to the waist or lower chest
topical anesthesianumbs only the tissue surface

Section 3

Question Answer
deep brain stimulationa device to STIMULATE THE BRAIN with mild electrical signals is IMPLANTED in the brain and is connected to a stimulator implanted near the collar bone.
gamma knife surgerya type of radiation treatment for brain tumors; the surgeon used gamma radiation to destroy diseased tissue while preserving the healthy tissue around the tumor
gamma radiationcharacterized by high energy and a short wavelength
electroconvulsive therapy AKA electroshock therapya procedure in which small amounts of electric current are passed through the brain, deliberately triggering a brief seizure in order to reverse the symptoms of certain mental illnesses
light therapyexposure to daylight or to specific wavelengths in order to counteract SAD
lobectomysurgical removal of a portion of the brain to treat brain cancer of seizure disorders that cannot be controlled with medication
thalamotomya surgical incision into the thalamus;this procedure destroys brain cells and is primarily performed to quiet the tremors of Parkinson's disease
neuroplastysurgical repair of a nerve or nerves
neurorrhaphysurgically suturing together the ends of a severed nerve
neurotomythe surgical division, incision or dissection of a nerve
