=====Corona radiata=====
{{ ::corona_radiata.gif|}}
[[White matter]] sheet that continues ventrally as the [[internal capsule]] and dorsally as the [[semioval center]]. 

This sheet of [[axon]]s contains both descending and ascending axons that carry nearly all 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]].

The long insular arteries originate from the insular portion of the middle cerebral artery and supply the [[corona radiata]] and the descending [[motor tract]].

The M2 segments also give rise to long perforating branches that travel posteriorly and superiorly on the insula and supply the [[corona radiata]]

Neurosurg. 2000 Apr;92(4):676-87. PubMed PMID: 10761659.)).

These branches must be preserved to avoid ischemic injury resulting in hemiparesis
