The best analogy I have is to think of your smartphone from the perspective of a normal user. You're used to it working fine. But suddenly it stops working fine. So a technical friend hooks up a cable and turns on debug logging and all you see is a wall of gobbledygook. [1] You ask what's going on and he starts describing an enormously complicated array of components and systems, and explains that he doesn't really know how most of them work, and that there are a bunch he probably hasn't even found yet. He can try this and that and the problem maybe gets better and maybe gets worse. You're forced to realize that the phone you trusted and thought you understood is beyond your ready comprehension.
Even that analogy fails in that a) minds are much more complicated, b) they aren't designed, so there's no expectation that they should make sense under the hood, and c) you cannot buy a new brain. If it's broken, well, maybe it'll get better and maybe you'll just have to get used to it being kind of broken and be grateful it works at all.

I have no idea how that plumbing is connected, but I have seen it happen myself, and apparently it's a not-uncommon experience for people with Alzheimer's: https://www.alzheimers.net/2014-04-03/connection-between-uti...
And yes, it is entirely freaky when somebody you have known for years starts talking utter gibberish and clearly expects to be understood. It feels deeply unreal.
Perhaps more common, but still quite rare at about one person per year worldwide, is something called foreign accent syndrome. In which a head injury causes someone with one regional accent to speak the same language with a different accent afterward, often resembling the accent of another region. Examples have included from US to British, US to French, an Oregon woman developed an Australian one, etc.
Sensory changes, changes in personality, and other things can happen with stroke or accidental brain trauma, too.
One particularly interesting case is hinted at in this article, but if you're interested your favorite search engine should turn up many more cases.: https://www.thecut.com/2016/10/the-boy-who-came-out-of-a-com...

Also, any book by oliver sacks is great if you'd rather read books rather than watch lectures.
This means that at best we can have a cause-effect understanding of the brain. Until we can describe the mechanics of the brain with a strong enough model where the resulting behaviours can be predicted, we can't truly understand what the brain is doing.
It does seem like a reasonable statement, but when you take a bit of time to think about it, billions of people disagree with it. A sobering thought.
> so there's no expectation that they should make sense under the hood
What doesn't make sense is that at first you deny a religious explanation, then without skipping a beat you ascribe (what can ironically be described as divine) mysteriousness and inscrutability to a body organ.
This not only doesn't pass the Occam's razor test, but also assumes a defeatist position that "we might never know for sure".
EDIT: I've taken uncharitable tone with this comment, and it may come across as too personal, which wasn't my intention.
It's actually not clear if brains are more complicated to understand than modern smartphones. Modern smartphones are designed using numerous abstraction levels - it makes it easier to design, but harder to understand if you don't know those abstractions. Brain, on the other hand, might have fewer fundamental algorithms/methods. In fact, most of the brain complexity could just be evolutionary quirks, some to make to make it's slightly more efficient, others to make some biological functions easier, etc. In the end, it might turn out that the actual human intelligence is not that hard to understand once we got through understanding all those design quirks.
This might sound ridiculous - after all a human brain looks so much more complex than an iPhone! But if you didn't know anything about transistors, analog circuit design, digital logic design, computer architecture, OS architecture, and software engineering (not to mention the complexity of cellular protocols), you would have a really hard time reverse engineering a smartphone.
Took months to get it all back.
I was on my way back home in Montreal. I consider English to be my second language. I have two mother tongues - Ukrainian and Russian. And, due to living in Montreal, I had passable French. So I lost ability to speak or understand French for a few days. After I re-gained it, it became visibly worse. Also I had short term amnesia - didn't know who I was, where I lived or where I was going from/to. Luckily, most of the things came back to me within the next few hours or days.
Brain is a bizarre device...
But baseless assumptions are ok?
For the example above, it could be
"i don't remember"
=> memory blocked
=> too much information interference
OR
emotional hinderance like fear of remembering
OR
insufficient information to recall
It is difficult to explain, but we are studying very basic primitive feedback responses to try to determine very complex problems. And we study mental conditions and neurological conditions separately that one hardly informs the other.Here is a theory: Prior chronic emotional pain can stymy recovery of cognition permanently. Beneficial emotions can activate new parts of the brain and create new personalities unlike what existed before.

If you want to understand better how the brain works, I really recommend watching the whole course.
If I were to guess, my brain would probably place Mandarin and English in "mother language" part of the brain and Japanese and Spanish part in the adjacent region. I wonder what I would lose if I were to sustain an injury. Would I lose one group over another group?
On another note, as with many American highschool students learning Spanish, I fell out of practice and now I can't really communicate in Spanish at all. When I do attempt to speak Spanish, I notice that I sometimes replace words in Spanish with Japanese ones. Can't be sure whether or not it's because of phonological similarities of Japanese and Spanish, or maybe my Japanese overwrote some of my Spanish.

I put Sweden in parentheses with a question mark because I can’t be sure that is in fact Sweden. It could also be the US. I read about it awhile ago and not in English. Sorry.
I have had a few incidents where, for an hour or so, I was exhausted and distressed and couldn't manage to speak English, only German. I could understand English, but not speak it.
I only found out recently (while reading The Story of Human Language) that he's actually huge[ly disruptive] in the field and came up with this line of thinking. That language isn't just an expression of culture or of general intelligence but is genetic.
His justifications were that 1, in cases where children were isolated from outside contact from birth, once reintegrated at an older age, they can become "generally intelligent and cultured" but can fail to ever learn a language which is very peculiar. 2, that culture can be wildly diverse but there are no non-speaking human groups just like there are no non-reproducing human groups. And 3, this particular case. Where damage to the brain affects very particular parts of not just speech but language without affecting other cognitive functions.
The term grammar is rather formulaic, but the problem is broader, if language ability is seen as an important factor for intelligence.
Theres an episode [1] of Helen Zaltzman’s fantastic podcast The Allusionist that deals with a similar story: a woman who has to essentially re-learn how to speak and understand English after a brain aneurysm.
I highly recommend giving it a listen if you’re interested; it’s only half an hour or so and really deepened my appreciation of how plastic and resilient our brains can be.
Normal day occurs and I rent a movie from the school library; 'M' [1931] starring Peter Lorre. German spoken, English subtitles. I functionally don't know German; English is my native language. All is well.
Partway through the film I notice my migraine symptoms coming on [grey-green soup-static eating into my vision from my optical peripheral, tingly numbness spreading up from my fingers, &c]. I know I'm screwed for the night, the best I can do is take pills and hope to "sleep it off" at this point. I decide to trooper it out and keep going with the movie 'cause I'm at a loss either way and I know this dance.
But then I realize that I could no longer understand the English subtitles, a new symptom for me at the time. I could read the subtitles, I knew they were English, I knew I knew I should be able to understand them, but I couldn't take their meaning. So here I am watching a movie where I don't understand the spoken or written language at all. All I had was my enjoyment of Peter Lorre, my appreciation of film noir, my love of film, and the inherent fundamental understanding of body language and facial expression.
About 75% through the film, one of my roommates comes in and sits down. "So, what're you watching?"
I swear he thought I was drunk.
Me: "This guy ... kill kids ... whistle. People ... not like guy."
Him: "Take your time."
Me: "This ... the people. Police ... no nothing. People ... this! ... these! ... people ... get guy."
Him: "OK."
Me: "The town... guy on trial. No police. Him! Bad guy. Whistles. Dead ... kids. City people ... guy on trial. No police."
Him: "I think I understand. Are you ok? Had too much?"
Me: "OK. Migraine. Watching movie. See? This ... Peter L-L-Lorre. Buggy eyes. Actor. Like a bug."
Him: "... yes. He's in this movie."
Me: "Famous actor! Now ... guilty from ... mob. The city. Death no police but ... dead whistling."
Him: "OK. Sounds like a good movie. See you tomorrow."
Me: "Yes. Tomorrow good ... movie."

I'm not kidding, I actually did talk like a drunken over-acted dramatization of Shatner. My actual language skills were out the window that night. I can't tell you how many times I dropped my Imitrex pills onto the floor before dropping myself into bed.
Yes, I'm better now against the migraines so I have little worries there on that matter but back then it was a going concern.
