The internal capsule is an area of white matter in the brain that separates the caudate nucleus and the thalamus from the lenticular nucleus.

It consists of axonal fibres that run between the cerebral cortex and the pyramids of the medulla. An axon or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neurons cell body or soma. ...

Components

The internal capsule is V-shaped when cut both coronally (on the same plane as the face) and horizontally/transversely (the same plane as the brim of a top hat). Duke Ellington wearing a top hat. ...


When cut horizontally:

  • the bend in the V is called the "genu".
  • the part in front of the genu is the "anterior limb". or crus anterius.
  • the part behind the genu is called the "posterior limb" or crus posterius.

There is also a retrolenticular and a sublenticular part to the internal capsule.


Fibers

  • The posterior limb of the internal capsule contains corticospinal fibers and sensory fibers from the body.

The corticospinal or pyramidal tract is a massive collection of axons that travel between the cerebral cortex of the brain, and the spinal cord. ...

Blood supply

Blood supply is similar to the other structures of the region. Striate arteries, which come off the middle cerebral artery, enter through the anterior perforated substance in the base of the brain. Striate arteries or Ganglionic arteries arise from the middle cerebral artery and supplies deep structures in the cerebrum including the internal capsule. ... The middle cerebral artery (MCA) is one of the three major arteries that supplies blood to the brain. ... The anterior perforated substance is an irregularly quadrilateral area in front of the optic tract and behind the olfactory trigone, from which it is separated by the fissure prima; medially and in front it is continuous with the subcallosal gyrus; laterally it is bounded by the lateral stria of the...

They can affect sensory and motor systems on the opposite side of the body, and possibly eyesight (to the contralateral visual field). Visual perception is one of the senses, consisting of the ability to detect light and interpret (see) it as the perception known as sight or naked eye vision. ...


Hearing should not be affected in a single capsule lesion, as this information crosses over to both sides of the brain while in the brainstem. Hearing is the following: Hearing is the sense by which sound is perceived. ...
