The internal capsule is a paired white matter structure, as a two-way tract, carrying ascending and descending fibers, to and from the cerebral cortex. The internal capsule is situated in the inferomedial part of each cerebral hemisphere of the brain. It carries information past the subcortical basal ganglia.

2023年6月5日 · The internal capsule is a two-way tract for the transmission of information to and from the cerebral cortex. It lies in the inferomedial portion of each cerebral hemisphere. On transverse sections of the brain, the internal capsule is a V-shaped structure with the apex pointing medially.

2023年10月30日 · The internal capsule is a white matter structure of the brain. It is located in the inferomedial part of each cerebral hemisphere. More specifically, it is situated lateral to the thalamus and caudate nucleus, and medial to the lentiform nucleus.

An internal capsule stroke is caused by interruption of blood supply in the middle cerebral artery (MCA) or one of its small branches. An ischemic internal capsule stroke is caused by an embolic blood clot coming from elsewhere in the body and blocking one of the small branches of the MCA, called a lacune lacunar stroke.

2024年9月30日 · The internal capsule is a V-shaped bundle of white matter fibers tucked away in the depths of the brain. It’s sandwiched between two important structures: the caudate nucleus and the thalamus on one side, and the lentiform nucleus on the other.

Symptoms and signs of internal capsule stroke include weakness of the face, arm, and/or leg (pure motor stroke). Pure motor stroke caused by an infarct in the internal capsule is the most common lacunar syndrome.

2024年8月20日 · The internal capsule (TA: capsula interna) is a deep subcortical structure that contains a concentration of afferent and efferent white matter projection fibers. Anatomically, this is an important area because of the high concentration of …
