What is a lobe?
Ascend (go up) through the neck and pass through the base of the skull
What is internal carotid arteries?
Most common cause of aphasia is ______.
What is stroke?
Features include: anomia, short phrase length, relatively good auditory comprehension, and poor word/phrase repetition
What is Broca's aphasia?
The capacity of neurons to adapt to a changed environment; in some cases, neuronal areas take over functions of damaged neurons
What is neuroplasticity?
This lobe is associated with visual processing
What is the occipital lobe?
Can cause visual loss if blocked
What is the opthalmic artery?
Can be simply defined as reduced blood flow to some area of the brain
What is ischemia?
Features include: notable anomia, poor auditory comprehension, and poor repetition ability
What is Wernicke's aphasia?
"Neurons that fire together wire together"
What is Hebbian learning?
What is the temporal lobe?
Follows the optic track
What is the posterior communicating artery?
Opening in an artery is reduced or blocked resulting in reduced or the stopping of blood flow through the artery
What is an occlusion?
Features include: normal phrase length, word-finding difficulties and attempts to self-correct, and paraphasias
What is Conduction aphasia?
One of the most popular ways to measure brain plasticity
What is an MRI?
This is where the primary motor cortex is located
What is the frontal lobe?
Hypothalamus and optic chiasm
What is the anterior cerebral artery?
When plaques cause a thickening or hardening of the arterial wall with a reduction in elasticity
What is arteriosclerosis?
Features include: normal phrase length, comprehension and repetition are relatively intact, paraphasic errors are rare, and frequent circumlocutions or non-specific phrases
What is Anomic aphasia?
The two structural ways to view neurodiagnostic imaging
What is an MRI and CT?
Bounded anteriorly by the central sulcus, inferiorly by the posterior end of the lateral sulcus, and posterior by an imaginary line
What is the parietal lobe?
Supplies the areas most closely associated with speech and language (another name for these areas is the ‘perisylvian region’)
What is the middle cerebral artery?
Formed exclusively of blood platelets causing a deterioration of the arterial wall leading to a rise in blood pressure
What is thrombus?
Features include: impaired initiation of verbal output, anomia, short phrase length, good auditory comprehension, and good repetition
What is Transcortical Motor aphasia?
The three functional ways to view neurodiagnostic imaging
What are fMRI, PET, and EEG/MEG?
