  • Brain blackout is kind of a dramatic word. I’m pretty sure the article is trying to refer to cortical spreading depression.

    https://www.nature.com/articles/nrneurol.2013.192

    This is a wave of decreased activity going across the brain. It’s not the whole brain though, just a portion, and it tends to happen more often in the posterior brain than anterior. That’s why visual and other sensory auras (posterior brain) auras are more common than motor/weakness auras (anterior brain). The visual aura itself is the spreading wave of decreased activity going across the brain. It happens in primary visual cortex, primarily dealing with lines and colors. Visual space is represented radially on the brain, so it can often be circular. The “fortifications” or lines on the edges some people see come from the fact that it’s neurons that deal with line detection. Pain usually follows shortly after, but we aren’t exactly sure how that works, and this article was posing a possible mechanism to help link these. The main bulk of the visual aura where it’s grey, blurry, and indistinct is the decreased activity itself in the visual cortex. The area can get larger as the wave spreads.

    Deja vu or jamais vu have been reported with migraines, though that’s a very rare aura in comparison. It’s all depending on what parts of the brain are involved with the cortical spreading depression for that migraine aura for that person in terms of what symptom will happen. Deja vu would be more temporal lobe. Temporal lobe is the most common localization for focal epilepsies. So deja vu as a symptom of a neurologic disease would more commonly be seen with seizures (focal seizures are sometimes called auras too, which gets confusing but are inherently different from what is happening in a migraine). But don’t worry, most deja vu is nothing to worry about.







  • There’s a lot of problems with this. Just some include that it’s a blog and doesn’t link to the actual study so it’s impossible to see what’s going on with the this report. They also never explain what this “reliability score” even means or what’s included in that. Then they start doing things like using a percent to compare the scores saying this is percent more reliable. But we still don’t even know what this score is, and comparing as a percent may not make any sense to say depending on what the scores are and how they’re calculated. Unfortunately you can’t really draw any conclusions from what’s in this article.


  • It’s a tough call. Many forums have a rule against changing the title at all. People posting are often used to this and post the title as is from the article. The idea being to help prevent editorializing and clickbait on the part of the poster. Every headline these days though seems to be some variation of blatant clickbait or so and so “slams” this or “destroys” that. At this point I probably trust randos on the internet to make headlines more than publishers.


  • I know. I was pointing out one of the nice things that this person can do, since they’re referring specifically to the default android sms handling app, is that android allows you to switch the default to whatever sms app you’d prefer to use. So if you don’t like the direction Google is taking theirs, you can find a different one that better fits with what you prefer.

    If you have an iPhone and don’t like the direction apple takes one of their default apps, like sms or phone calling apps, you can’t change the defaults that handle those and other phone functions.
