corona radiata
In neuroanatomy, the corona radiata is a white matter sheet that continues ventrally as the internal capsule and dorsally as the semioval center. This sheet of both ascending and descending axons carries most of the neural traffic from and to the cerebral cortex. The corona radiata is associated with the corticospinal tract, the corticopontine tract, and the corticobulbar tract.
==Structure==
Projection fibers are afferents carrying information to the cerebral cortex, and efferents carrying information away from it. The most prominent projection fibers are the corona radiata, which radiate out from the cortex and then come together in the brain stem. The projection fibers that make up the corona radiata also radiate out of the brain stem via the internal capsule. Cerebral white matter is commonly regarded today as an intricately organized system of fasciculi that facilitate the highest expression of cerebral activity.
