True or False: The EEG is not as sensitive in picking up immediate changes in blood flow to the brain, as
imaging techniques such as CT and MRI. - False

b. Dying during status epilepticus
, c. Dying from a medication overdose

structures important for memory in his/her _____. - left temporal lobe
What is the 60 Second Simple Stroke Screen? - left temporal lobe
True or False: The mechanism of the Vagal Nerve Stimulator is thought to be secondary to the vagus
nerve's widespread subcortical and cortical centers and vagal afferent fibers projecting to multiple
brainstem nuclei, including regions providing norepinephrine and serotonin, thought to play a major role
in seizure and mood modulation and increases free GABA, a principal inhibitory neurotransmitter in the
brain that plays a role in suppressing seizures. - True
