The Long and Winding Road(s)
The major cortical artery (name and side) that is likely the site of damage if the person has aphasia.
What is the left middle cerebral artery?
A lack of blood flow and, therefore, oxygen, to an area of the brain.
What is ischemia?
The structure in the central core of the brain that serves as a relay station for all incoming sensory information that is then transmitted to various parts of the cortex.
What is the Thalamus?
The inability to recognize a stimulus, not related to primary sensory loss.
What is agnosia?
The artery (side and name) that is most likely to be the source of the lesion in a patient with prefrontal cognitive and personality deficits and hemiparesis of the left foot and leg.
What is the right anterior cerebral artery?
When fatty deposits build up in the arteries due to atherosclerosis, eventually occluding the artery and causing a stroke.
What is thrombosis?
Secretes Melatonin and influences motivation.
What is the Epithalamus?
The primary auditory cortex.
What is Heschl's gyrus?
Collateral blood flow that allows for parts of the brain to be perfused if there is loss of blood flow in the primary pathway. The Circle of Willis is one of the primary routes for this.
What is anastomosis?
When a piece of fatty plaque breaks away or a blood clot forms traveling to the brain and causing a blockage and, therefore, a stroke.
What is an embolism?
Influences the endocrine system, the autonomic nervous system, and regulates body functions.
What is the Hypothalamus?
Smell travels from the olfactory nerve to many parts of the brain including those these 2 parts that process appetite and form memories.
What are the hypothalamus and hippocampus?
The arteries that perfuse the deep structures of the brain, including the diencephalon, choroid plexus, midbrain, etc.
What are the central arteries?
An area of dead brain tissue.
What is an infarct?
Imaging technique using x-rays that is not well suited for identifying ischemia, but good for detecting hemorrhage.
What is a CT scan?
When you hear a siren and see the flashing lights of a police car behind you, these sensory systems are activated and trigger processing in these primary cortices in your brain. The information is then processed in these 2 subsequent areas resulting in you pulling over to the side of the road.
What are the visual and auditory systems, the primary sensory cortices of the occipital and temporal lobes, the unimodal association cortices (allowing you to identify that you are hearing a siren and seeing a police car), and the polymodal association areas (allowing you to make the decision to pull over)?
The artery that is most likely to be involved in a patient with cortical blindness.
What is the posterior cerebral artery?
The arteries that connect the major cortical arteries, forming the Circle of Willis.
What are the anterior communicating artery and the posterior communicating artery?
Imaging technique that measures blood flow changes in response to oxygen usage. Is able to identify the eloquent part of the brain for a given task.
What is functional MRI?
The 4 components of the 3-neuron sensory pathway of the trigeminothalamic path, from most peripheral to most central.
What are the trigeminal ganglion, the brainstem, the ventral posterior medial nucleus of the thalamus, and the parietal lobe of the cerebral cortex?
