Brain aneurysm treatment. Coloured angiogram (blood vessel X-ray), in frontal view, of the head of a 49-year-old patient undergoing treatment for a brain aneurysm. A brain aneurysm is a dangerous swelling in a brain blood vessel. This treatment involves inserting metallic coils (black, centre) into the aneurysm. The X-ray is used to show the position of the coils, placed by electromagnetic controls, and a contrast medium shows the blood vessels (red). The coils cause clotting of blood in the aneurysm, and eventually the blood vessel reforms its wall. This technique is an alternative to direct surgery. The blood vessel being treated here is the basilar artery that supplies the base of the brain.

It’s a simulation of Deep brain stimulation…Nice!

In this photo during neurosurgery, you can see the layers of the head removed & retracted until the brain is exposed.
First, you see the retraction of the scalp. Then you can see the top of the skull cap, or calvarium. After that you can see the dura mater of the meningespeeled back (the meninges is the protective covering over the brain & consists of the dura mater, arachnoid mater, & pia mater), finally revealing the cerebral cortex of the brain. You can even see the meningeal blood vessels.
Amazing.
‘Til next time.
Deuces.
