Vestibular Sense Puns

Proprioception: awareness of your body position. Two sensory mechanisms for this are muscle spindles and golgi tendon organs, both utilizing collagen.

Muscle spindles are located in muscle fibers and tell the body how stretched the muscle is. For example, close your eyes and then bend your arm to 90 degrees. With your eyes closed, the muscle spindles in your arm are telling the brain how stretched they are and that helps you know it is bent 90 degrees without having to look at it.

Golgi tendon organs are located in the tendons and sense tension. Their role is to inhibit muscle contraction if the stress becomes too strong (this is to prevent damage to the tendon and the muscles). This can be overridden by adrenaline, which explains why people get "superhuman" strength during fight or flight responses. They probably also provide some information to your brain regarding your position.

Vestibular: awareness of spatial orientation (upright, upside down, sideways, etc). There are canals in your inner ear that are filled with fluid and rocks. Movement of the fluid and small rocks stimulate hairs in the canals, indicating your spatial orientation. Perhaps deformation of these canals contributes to nausea, motion sickness, and/or vertigo.

Nerdy question from an undergrad studying human bio:

Humans also evolved a sense of balance (vestibular sensation). We know which bodily position we're in (propioception), partly due to the vestibular system affected by gravity.

Which sense door does this fall under? When we sense balance, it doesn't seem to come through the door of touch, nor hearing (vestibular system located in the ear), nor thoughts-cognition. Are sensations of balance/gravity modeled into the six-doors framework, or where does this fit into the Buddhist model of human perception? Thanks!

I am finding conflicting information on these terminologies. Here's what I have gathered so far.

1. Proprioception - sense of body position in 3D space

2. Kinesthetic - related to body movement (not sure if balance is included)

3. Vestibular - related to body balance, relies on ear structure for linear and rotational acceleration

Is this correct? Also, is vestibular and proprioception two distinct concepts?

I have an ANKI card saying that proprioception = kinesthetic sense, but that is not what KA video refers to. I would sincerely appreciate your help. Thank you.

> In our conversation, we discussed the origins of the self, intimations of mortality, what those who champion a singularity-an immortal union of brain and computer-are missing, and how virtual reality could perhaps push the self into entirely new modes of experience.

> It's not that your sense of self literally jumps over into an avatar or into the robot, but what you do is you create a complex causal loop by which an external tool-a robot, a second body-is being made directly controllable by you, with your own mind.

> You don't buy it? Why couldn't we upload a self?

> Then you would maybe have a sense of self jumping into an avatar, but you would not have all that low-level embodiment, the gut feelings, the emotional self-model, the sense of weight and heaviness-all that would be gone.

> It also has a philosophical problem because the deeper question is, of course, what would jump over into the avatars if there is no self? It's just like discussing reincarnation with Buddhists; what is it that would be reincarnated-your neuroses, your greed, your ugly childhood memories? If there is no substantial self in here right now, what is it that you would copy into an artificial medium?

Kind of a repost to something I had posted in r/parenting 2 months ago. The behaviour has only continued to become more frequent, and last for longer periods of time.

Backstory: My son is almost four and has a substantial language delay. He goes to speech therapy and occupational therapy, and has been to see a neurologist, as well as a psychologist because he has some behaviours that suggest autism. The psychologist said he falls just outside the range where she would diagnose him with autism; we are supposed to revisit in 6 months.

The behaviour: A little over a year ago, I started to find him in the hallway walking in circles. The behaviour progressed to include walking in circles in the living room, or our patio, with a vacant stare on his face. His name is Alejandro, and for a while we have been saying there are two Alejandros. When he does these behaviours his facial expression changes and his eyes go blank, and you can tell just by looking at his face if he's the cute interactive Alejandro, or the one who's in his own world. Sometimes he has a really creepy smile. Around four months ago he started also vocalizing when this happens, and the sounds he makes are different from the normal jargon or speech sounds he will make - I am not sure how to describe it, but it sounds like moans, or someone who is deaf, maybe?

It seems to be happening more and more, and for longer periods of time and it's really freaking me out, and I'm not sure how to even describe it as a symptom - he actually started doing it the last time we were with the neurologist, and she didn't think it was worth noting. Everyone seems to be telling me it's maybe a stim, or it's just not something to worry about.

It has, in the last few months, progressed to be something that happens tens of times a day, and sometimes for long periods of time. While he will have the vacant/confused look when walking in circles, he will now also vocalize and have this look when sitting at the table, or today when we went for a walk. He will not respond to you while this is happening, but sometimes if you look him in the eyes and call out to him he will snap out of it.

I was actually taking a video the other day of his counting to show his speech to someone, and the first 20 seconds of the video is him just staring blankly, moaning, and then he suddenly snaps back and starts engaging with me and counting.

To me, this is concerning. Does anyone else have a kid who does something like this?

Hi everybody,

In early February 2020 I had what we assume was Covid. I say assume because Covid wasn't even really a thing at the time, and they weren't testing, but I did test negative for the flu. After losing my sense of taste and smell, coughing, and doing relatively ok, my life spiraled into a living hell. I had diarrhea, abdominal pain, my legs would feel heavy, I'd have premature ventricular contractions, severe dizziness, sleep apnea, I couldn't stay awake, had post exertional malaise, severe fatigue, my muscles would twitch, my muscles would tingle, my eyes would weird things, I would get dizzy and off balance, I was sensitive to certain lighting, i would see white flashes of light and weird floaters, my heart would race, I had some tinnitus, I had brain fog, I lost 20 lbs, 160 to 139, and my adrenaline and anxiety was off the charts. Symptoms just seemed to come and go and change, and the anxiety by itself was life ruining. I wanted to tell everybody that I did recover to the point where I was running a 5K faster than I did before I had Covid. All in all it took around a year and 4 months before I was back to being fairly normal, but I absolutely worked hard at it (Edit: this isn't to say pull your self by your boot straps or that you aren't working hard enough, see edits below). After literally dozens of doctors visits and specialist visits, I was diagnosed with POTS and vestibular migraines. I wasn't formally diagnosed with Chronic fatigue, but it was pretty obvious that I had that as well.

Here are some things that worked for me

1. Magnesium citrate
2. vitamin D3
3. gatorade and lots of water (staying hydrated was probably equal to exercise for helping alleviate my POTS. I would generally make sure I ate enough and got super hydrated and then do physical activity)
4. avocados
5. eggs
6. brown rice quinoa mix from Costco
7. lentil indian mix from Costco
8. generally making sure I ate clean and ate enough to gain weight
9. most importantly, I started by walking, then jogging, and then running. If you have POTS the only way to get better, and by better I mean being able to function as a human being, is to exercise. The POTS doctor recommended a rowing machine which I bought. I also bought a treadmill for winter, and did Yoga. (NO WEIGHTS!) Edit: 10) I also added Kerry gold Irish butter to a lot of things.

After runs or jogs, I would sometimes be so exhausted I would have to just lie down and sleep. I can't make any guarantees, but what I

I was diagnosed with sudden onset vertigo in September 2020. Since that day I've been dizzy & nauseous for every second of it. I'm not able to work and am very limited with what I can do at home. I'm not able to do any activities I used to love and anything physically gets bad fast. Tv, reading and monitors can only be used for minutes before I feel like I'm going to vomit. I have a huge sense of guilt no being able to provide income for my partner, not eligible for unemployment and have been denied SS 2x. I have seen dozens of specialist, countless medications and plenty of non traditional medicine. I also suffer from major depressive disorder and have had SI attempts in the past. I have had a pretty good handle on my mental health with weekly talk therapy and regular physiologist meetings. What scares me is how much intrusive thoughts have crept back in. I've also been more sympathetic to a friend's suicide dude to very painful disease. Idk what I'm hoping to get out of this post but this group is the only place I feel comfortable sharing this with right now.

Got my instrument rating 8 months ago, and I had some experience with IMC with an instructor onboard. I had always known that single pilot IFR in IMC is hard, but I also know it was time to test my skills and prove to myself that I can do everything the checkride tests for in real weather. So in some sense, this is a checkride flight for myself.

I selected a stormy socal day for this flight. Radars show light-moderate and rarely heavy precip throughout the area, but better to the west, with ceiling variable between 800 and 1500agl. visibility varies depending on precip, as low as 1.5miles in the rain and as good as 6miles at some places. Wind is wack, coming from the north and east, which is completely opposite of the general flow, but mostly less than 10kts. Top of the cloud is at least 8000ft, and freezing level around 7k. I know that my flight will not take me above 5k, and no icing is forecasted or reported at that level. No convective weather, and turbulence according to forecast and PIREP is some chops in the cloud. The approaches I will fly can take me as low as 300ft agl, and I am comfortable transitioning to visual around 500ft agl. With all that, I decided to launch.

At takeoff, there was no rain but the ceiling was low, 800ft. I knew I would transition to instrument early on and was prepared for it. The chops were slightly more than I expected, but not something concerning as I still have great control of the plane and can see my instruments. I continued my scan, making sure to trust the instrument and not my vestibular system, and continued the departure.

Climb and cruise was all in thick soup, sometimes going through light precip. ATC vectored me all the way to final approach course of RNAV RW8 at KCMA, where I plan to stop and get a burger. The approach was pretty stable given the not so light wind, and I broke out at 1200ft. I continued to follow the glide path until close to minimums, and made one last GUMPS check. All good. But I don't know what got to me, in all the excitement of flying in the soup, I somehow made one of my worst landings. Not flaring enough, I bumped the nose wheel with some energy left and the plane bounced a bit back. There was some light porpoising and I stopped it fairly quickly. Cursing my landing, I taxied all the way down the runway and to the Waypoint Cafe.

Takeoff and departure from KCMA was routine, with good visibility and MVFR ceiling. The cr

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Hey all! To re-introduce myself, I'm a combat sports fan who happens to be a physician in the US. I've trained boxing, kickboxing, MT and have competed as an amateur too. I also enjoy writing about the sports med/neuro aspects of this crazy sport, and hope to provide a different perspective to the typical breakdowns you may see. I wrote this brief post in light of Giga Chikadze's upcoming fight against Calvin Kattar this weekend. Check out my IG page if this kind of stuff interests you.

All fighters know that it’s the strike that you don’t see coming which does the most damage. This makes sense on a general level, but is there any science behind it?

💥 Fighters through the ages have trained specifically to increase their ability to take head strikes, mainly via neck hypertrophy exercise. However, more recent research suggests that it's the reaction time needed to quickly stiffen the neck in time for impact which could be more important than simply increasing size or strength. Fighters known for their “chins” may therefore just have excellent eyes. They can anticipate attacks while avoiding focusing too much on any one spot (like driving a car). Reactive drilling and fight simulation to instill pattern recognition and reflexes should therefore remain the most crucial parts of fight prep.

💥 There's still much to learn about the inner workings of the brain, but studies have shown that visual attention and focus can temporarily suppress parts of the brain’s vestibular cortex (the part which is important for balance and gives us the ability to perceive our bodies in relation to the external environment). This may happen via decreased release of glutamate, the molecule responsible for “turning on” many brain functions. Therefore it MAY be possible that a fighter's vestibular function is diminished when he i

Do your worst!

Hey guys. I’ve had vestibular migraine for over 6 months now, the primary symptom was just feeling motion sick with any movement. Laying down was my safe space so to speak. Now however, I feel dizzy almost 24/7 and just really weird and uncomfortable. It will sound odd, but as soon as I lay down, I feel like a very strong urge to get up and sit or stand as if that makes me feel a little more comfortable, less dizzy. I have been checked out for BPPV recently and do not have it, and both my neurologists believe I have vestibular migraines as my choleric testing was fine and don’t show signs of neuritis like vertigo or spinning. Anyway, just wanted to know if anyone else experienced dizziness that is very intrusive and irritating as I just feel very hopeless and scared right now.

I'm surprised it hasn't decade.

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂

It really does, I swear!

Because she wanted to see the task manager.

I am now 2 months in with balance issues that seem to match some kind of vestibular dysfunction. This all started when I got out of bed and was so off-balance I could barely stay up (no spinning vertigo). Went to urgent care, they saw ear wax impaction so they flushed it and it felt better. A week later, the same thing happened. This time I saw my GP and she thought it was vestibular neuritis and sent me to a vestibular PT. The PT performed the Dix-Hallpike maneuver to check for BPPV and I had no reaction. Then, recently I saw a neurologist and he thought my onset sounded a lot like BPPV, did the Dix-Hallpike and again, no reaction. I haven't had any other 'acute' attacks, just an off-balance feeling and a sense of movement while sitting and laying down. The neurologist mentioned in passing that tests like Dix-Hallpike aren't 100% so it made wonder, is it possible to have BPPV while still testing negative via the Dix Hallpike?

They’re on standbi

I know that dpdr can be caused by many things, but I've personally noticed something interesting that I wanted to inquire about here. First, some background/facts:

1. I have atypical ear anatomy in one of my ears. This runs in my family. I'm not sure what it is in particular, but I'm curious to get it x-rayed one day to find out.
2. My ear feels "full" now and then- even though I've checked it and earwax is not the issue (although it has been in the past)
3. I clench my teeth at night and my jaw gets tight- I notice the ear fullness is worse when my jaw is particularly tight.
4. DPDR symptoms get progressively worse with increases in ear fullness or jaw tightness.
5. I understand that sinuses are all connected and that, when these are clogged, it can cause more than a stuffy nose (e.g. ear fullness)
6. Lastly, we've all had a cold and felt like your head was in a cloud- yes? ...doesn't that kinda remind you of DPDR?

So, I'm not suggesting that all DPDR is caused by this, but I wonder if it could be linked to symptoms in some cases? It would make sense that we feel out of sorts if our vestibular system is not functioning properly. I guess I'm just curious to hear your thoughts and see if anyone else has any insight/input into the matter.

My hypothesis, for me, is that the majority of my DPDR in the past has largely been caused by trauma and a resulting defense mechanism to numb myself and dissociate. I believe that excess glutamate may be at play as well, but I also wonder whether the ear/vestibular/sinus issues are worthy of consideration!

Share your thoughts if you feel so inclined :)
