In neuroanatomy, the corona radiata is a white matter sheet that continues inferiorly as the internal capsule and superiorly as the centrum semiovale. This sheet of both ascending and descending axons carries most of the neural traffic from and to the cerebral cortex .
Location of infarct Presentation Pure motor stroke/hemiparesis (most common lacunar syndrome: 33–50%) posterior limb of the internal capsule, basilar part of pons, corona radiata It is marked by hemiparesis or hemiplegia that typically affects the face, arm, or leg of the side of the body opposite the location of the infarct.
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
Results showed a significant 14% reduction in recurrent stroke rates and a 21% decrease in stroke-related deaths for those using a salt substitute compared to regular table salt.
From their origin in the primary motor cortex, these nerves pass via the corona radiata to gather in the internal capsule before crossing over to the opposite side (decussation) in the medullary pyramids and proceeding down the spinal cord to meet lower motor neurons in the anterior grey column.
They did a stroke test called the Cincinnati test a few times, and at one point, I couldn't hold up my left arm at all. For a brief period, I even lost all vision, but I could still hear and talk ...
Structures such as the corona radiata, occipitofrontal fasciculus and uncinate fasciculus project to the claustrum from frontal, pericentral, parietal and occipital regions. [21] Reciprocal connections also exist with motor, somatosensory, auditory and visual cortical regions. [13]
At 24, Wilson-Garza became that anomaly: a healthy, young person without any history of high blood pressure, diabetes, obesity or clotting disease, and a never-smoker who had a stroke.
