sulcus

  • The researchers looked at MRI brain scans of a large group of healthy adults. In particular, they were looking for the paracingulate sulcus (PCS), a fold near the front of the brain. There’s a lot of variability in the PCS: some people have quite distinctive folds, others have barely any. It’s in a part of the brain known to be important in keeping track of reality, which is why the researchers chose to study it. Of the 53 people selected for the study, some had this fold on both sides of their brain, some had it on one side, and some had no fold.
  • The participants saw some full well-known word pairs (“Jekyll and Hyde”) and some half pairs (“Jekyll and ?”). If they only saw half of a pair, they were asked to imagine the other half (“Hyde”). After each pair or half pair, either the participant or the experimenter said the whole pair aloud.
  • Once they’d seen all the pairs, the participants were asked two questions about each phrase: Did you see both words of the pair, or just one? And who said the phrase aloud, you or the experimenter?
  • People who didn’t have the fold on either side of their brains did worse on both questions—remembering if something was real or imagined, and remembering who’d done something—than people whose brains had the fold. But they felt as confident in their answers, meaning they didn’t realize they’d been mixing up internal and external events.

Along with schizophrenia, the PCS would also be a place of interest for study on the ability to lucid dream.

My take on the variety of gyri and sulci of the human brain because I have a quiz for neuropsych tomorrow and I decided to spend my day drinking with co-workers.

My artistic capabilities are clear indications of left hemispheric dominance (but really brain lateralization is a myth).

P.S. The angular sulcus is incorrectly labelled as a gyrus.

anonymous asked:

My horse recently got their shoes pulled - like a month ago- but is really tender on them even on sand. Is there anything I can do to make life easier for the poor baby while his feet go through the transition?

Very hard to give advice without photos, because there are a few possibilities for what it could be.  Normally after a month or so the hooves will have started to callus unless there’s some underlying issue…

The first and most obvious thing to come to mind is disease, check to make sure there’s no thrush or white line disease and the central sulcus is open… no entry wound for abscesses or laid over bars, things like that.  Simple diseases are fairly straightforward to treat.  An anti-septic, bacterial, fungal combo treatment works well, my go to treatment is a few drops of tea tree oil every few days.  Some people prefer to buy over the counter remedies or do something like an apple cider vinegar soak.

Another thing to watch for this time of year is laminitis, I don’t know where you’re located, but if you’re in the midst of spring and your horse is on all this sugary new grass it’s a possibility.  Sub-clinical cases are fairly common, and when the horses aren’t lame most owners don’t even notice.  Laminitis comes on gradually, I’d check the digital pulse on all four limbs to make sure it’s not strong or really bounding.  Feel the hoof and make sure it’s not really hot when the horse hasn’t been working, check for weird growth rings or abnormality like stretched white line, etc… 

If the shoe was removed and the hoof was aggressively trimmed, that can cause a tender foot as well that could potentially take a while to grow out and toughen up.  Most farriers I’ve met wont trim much beyond rolling the toe a little bit after removing a shoe when the horse is transitioning (even though sometimes it looks godawful) because they’re less likely to be sore. 

Just to keep him comfortable for the moment, you may want to consider getting him fitted for boots.  Ideally they’d have an insert that would stimulate the frog, but even just regular boots would provide some relief.  The advantage of boots is that they aren’t much more expensive than shoes, really, and they’re removable too, which is nice.

I’ve also heard of cutting a homemade pad out of hard styrofoam insulation and duct taping that one to the hoof as a temporary measure, if you decide to try that make sure you use short pieces of duct tape and really reinforce the toe, because it’ll be taking the most abuse.

How is his body condition?  If he’s deficient in anything he could be having trouble growing more hoof, in which case I’d suggest adding some kind of ration balancer to his feed or a supplement specifically catered to hoof health, there are plenty of these on the market.  If he’s overweight I’d try a supplement such as simmIRdown which was developed for anxiety but also works really well for weight management and as a laminitis preventive… Which now that I think about it I should start feeding that to my overweight escape artist pony.  I think the only major downside to this product is that you have to buy it from Canada, but I know of people in the states who have ordered it online. 

I hope that helps, transitioning can be so stressful.  I had two transitioning here last year and they had ugly feet for the first little while, but once the frog and digital cushion came back into play their hooves started growing out much tougher…  Sometimes they just need an extra little bit of help at the beginning.  Good luck with it!

@s-uperflu0us (can’t tag you :/) sorry this took so long to get to. Basically i’m seeing some disease there in the central sulcus of the frog with some flaps covering it. Those flaps can come off and the disease should be treated with something antibacterial. The medial(inside) heel can come down a little more, and the bars can be straightened. There are some tears in the wall at the toe quarters where dirt has gotten in. I would give the entire toe and toe quarters a good bevel to relieve pressure and possibly remove the outer edge trapping the dirt if you have the knife skills. There seems to be some congested sole up at the toe which may free itself or may not, just make sure there’s nothing crumbly and gross underneath.

Hello docs, i have a small problem.  i had unprotected sex with my girlfriend (shes clean) about 3 days ago, it went fine but a day after i looked at my penis and on the right underside of the inner foreskin when pulled back is red and swollen, the 2nd day it started collecting puss in the sulcus..  please help because im very confused at the moment, i will go to a doc on wednsday to check..   oh, and also this swollen area is a painful itch.. the rest of my penis looks fine..
thank you in advance
Marc

hey,
just got back from the dermatologist this morning.. i told her what i had the past week and she immedeately found out that i have a fungal infection.. its on my knee, on my toungue and was on my penis…  1 week of no sugar and pills, cream, gel.. then im good..

well, thanks for all the help and i hope this post will help someone in the future!  marc

Day 2
I woke up without my MP on but went to bed with it. As I can see the Sulcus is fully covered and is just touching the Corona this puts me back to a CI 3 close to where I was when I stopped T-taping. That is a lot of coverage for one night. I hope tomorrow I will be back to a CI 4 my goal is to get to CI 9 I will post a link to the chart. Happy restoring! 😀
