Vestibulo-ocular reflex neuroanatomy

[@alanwaterman1328]

Great clip length. Good level of detail. Well summarized. Well done.

My goodness, the body is absolutely amazing! I’ve been studying this crap for decades, and when I go back to refresh my memory and learn any new stuff…… I am Consistently in awe!

I'm having my tea at this time. Amazing video , well explained with all organised parts that are involved. THANK YOU SO MUCH ❤❤

[@m_m786]

Very informative ❤💝

[@divinesagbohan9875]

thank you very much for all your videos... you are helping more than one with your explanations. So well explained... you made it easy to understand. thank you

Amaaazing, Sam. I love your videos and the energy you give out!! I"m a med student and you make anatomy feel real and tangible and like there is some kind of logic to it, instead of just pages and pages of bland latin bullet points that make my brain go numb and make me question if I really want this.. Your videos have a big impact, please never stop making them!

[@nb2028]

Hi Sam, Thanks for your effort and know-how. I hope you would keep posting anatomy videos even after retirement and the University shall provide access to their facilities for that! Greetings from Finland.

He's not retiring anytime too soon.🎉

Fantastic video, genuinely. I watched this to solidify my understanding of the VOR. I have one suggestion that might help more visual learners, such as myself. Similar to how you have close-up and labeled frames of the inner ear and eye muscles, I think adding a diagram of the overall reflex would be very beneficial. Googling vestibulo-ocular reflex generates a ton of good diagrams that can really emphasize what you are saying in the video. Showing the diagram while you're speaking, and highlighting areas on the diagram as you are talking about them, can accomplish this goal of assisting visual learners. But anyway, this is a great video so thank you for making it!

so good. Very informative

Fantastic video

I sometimes have vertigo if my vision is fixed on an object while I'm moving. This happens when I'm hiking and looking at an interesting plant while pushing on. I've learned to stop, look up and look at the distance.

I love all your videos, and I've learned a lot from you. We could go on for hours with this level of intricacy and syncing between the two sides of the ear, and the eyes, and so on. This begs the question, doesn't it: Can a mindless, purposeless, goalless "natural" selection process "figure out" HOW the two opposing sides of the signals must "compute" in flesh to make the eyes stay fixated? More so, when such mindless and purposeless process has NO means to "record" the failures in its attempt to reach a goal, when said mindless process could, by definition, have no goal?

[@SamWebster]

It's not computation, it's more electromechanical. A camera gimbal does the same thing. It's not purposeless as such - if the change increases the chance of survival the change persists in the offspring. A good example is the evolution of the jaw. Before the jaw there were jawless fish. The jaw evolved and the fish with jaws ate almost all of the jawless fish. The jaw is now everywhere. You're right about the inability to record failures. We have no knowledge of the failed mutations that did not give a survival advantage. It's funny how the balance sensing system and the hearing sensing system are very different and yet use the same hair cells and are in the same, combined organ.

I love all the toys he has 😊

No doubt you teach anatomy in a way that it tends to adhere on the surface of neurons.

[@ryukoli4707]

My Mother is suffering from vestibular and balance issues. Will let her watch this video, so it will help her understand her problem. Are there any other things that may contribute to her dizziness/wooziness?

[@SamWebster]

Unfortunately, yes, there are many things. Dizziness is most commonly from a vestibular cause, and less commonly from a cerebellar or other cause. I am just an anatomical scientist though, and not a clinical doctor. I have benign paroxysmal positional vertigo so can sympathise. Episodes of vertigo can be fixed or reduced by a clinician that has experience in these things.

[@ryukoli4707]

@@SamWebster she is scheduled to see a specific PT for that assistance. Hopefully, she will get some improvement. Can't risk her falling...... unfortunately. She has actually had rather serious falls with her walker. Her weight is greater than the walker AND........... Otherwise, she wants to get up and go!🤞🏻

[@vibrantvegansocietyofghana3903]

Let her see an Osteopath

[@qwertyuio555]

I have macular hole.can I improve this without surgery,by retraining my visual cortex...?

Why does the fluid in the Semi circular canals crystallize?
