100
Loss of vision in the left or right visual fields of both eyes due to occipital lobe damage.
What is homonymous hemianopsia?
100

What is CT scanning?
100
Large fiber bundle connecting the two hemispheres.
What is the corpus callosum?

The topographical representation of the body on the primary motor and primary sensory cortices.
What is the homonculus?
200
Responsible for equilibrium and audition.
What is the Acoustic or Vestibulocochlear nerve (CN VIII)?
200
Inattention to the left side of stimuli
What is unilateral spatial neglect or left neglect?
200
Imaging technique with many variations good for viewing anatomical detail and distinguishing gray from white matter
What is MRI?
200
Controls the "fight or flight" response as part of the _________ __________ _________.
What is the sympathetic nervous system, a part of the autonomic nervous system?
300
The landmark which separates the frontal and temporal lobes.
What is the lateral fissure or Sylvian fissure?
300
Responsible for vision.
What is the Optic nerve (CN II)?
300
Results from damage to the left temporal-parietal region.
What is Wernicke's aphasia?
300
Measures blood flow changes in response to oxygen usage. Is able to identify the eloquent part of a brain for a given task.
What is functional MRI?
300
When fibers cross to make contralateral connections. Occurs in the ________________.
What is decussation? Where is the medulla oblongata?
400
Central core of the brain containing the __________, which integrates sensory, motor and cognitive functions with the cerebral cortex, and the ________________, which controls the autonomic nervous system
What is the diencephalon containing the thalamus and hypothalamus?
400
Responsible for taste on the anterior 2/3 of the tongue, secretion of saliva and tears, and for facial expression.
What is the Facial nerve (CN VII)?
400
Slow, halting language production characterized by telegraphic speech and word retrieval difficulties, resulting from damage to the inferior, posterior frontal lobe.
What is Broca's aphasia?
400
Imaging technique that delineates white matter/axonal pathways.
What is diffusion tensor imaging?
400
Four cavities which produce, circulate and stores CSF for waste removal, homeostasis of intracranial pressure, and protection of the CNS from injury.
What are the two lateral ventricles, the third, and the fourth ventricles?
500
Controls emotional drives regarding visceral and vegetative functions via the amygdala and consolidates memories via the hippocampus
What is the limbic lobe?
500
The 4 cranial nerves that have both sensory and motor functions.
What are the trigeminal (V), facial (VII), glossopharyngeal (IX), vagus (X)?
500
Results in apathy, diminished drive, executive dysfunction, confusion and confabulation.
What is dorsolateral prefrontal syndrome?
500
Test measuring electrical output of brain vs. test measuring electrical output of muscles.
What is electrical encephalography (EEG) vs. electromyography (EMG)?
500
The cortical white matter fibers that connect within hemispheres, between hemispheres and which ascend and descend to integrate sensory and motor functions.
What are association, commisural and projection fibers?
