The anatomy of the blood supply to the brain, including the circle of Willis (or circulus arteriosus). I talk about the vertebral and internal carotid arteries, the basilar artery and the circle of Willis, and mention the cerebral and cerebellar arteries, the blood-brain barrier and the idea of cerebral perfusion pressure.

Hey mate. This has been really helpful for me, enlightening, especially your sit down bit at the end. I had a pterional craniotomy last year to remove an Olfactory Groove Meningioma, and I've coped with symptoms of intracranial pressure episodes of varying degrees ever since. Having a grasp, an appreciation, anatomically on what is going on assists greatly with my coping strategies (especially when medical people I have to deal with seem too scared to or can't be bothered telling me what is going on, like I'm an idiot). Knowledge is power. I'm glad you persevered with making these videos. Your more recent ones are a testament to your learning and perseverance. They're terrific.

Thank you for this video. September, 2023, I was told that I had a total occlusion of my right internal carotid artery near the bifurcation. I was told I had connecting arteries that would back up the needed blood supply in my brain. You’ve explained those connections.

He does it needlessly dude. You’d think he would’ve practiced this before recording but at times it seems like he doesn’t know what he’s doing. He knows what he’s talking about but doesn’t seem to know what he’s doing.

Not even a minute, you had to say the E word. Is there some board of regents or governing body with the power of purse strings that requires we must mention evolution when discussing a topic that is not at all related to speculative fiction or superstition? I reasonable expected to hear descriptive science on this channel.
