Ask Lemmy

We might be in one, there's talk that Alzhiemers might be a prion disease that happened as a result of using cadavers to obtain human growth hormone. Which was then given to folk in a potentially misfolded form...

I'm sure for most people, this is somewhat disturbing.

However, I have at least 3 voices going in my head at any given time, and they cycle.

One is figuring out what's happening.

One is analyzing what was just happening.

One is talking to itself.

All while I decide which one is the most interesting.

I had a girlfriend who was born without this connective tissue between her brain hemispheres.

Other than being weird, for reasons that could be explained myriad other ways, she was able to control each eye independently when she wanted.

Watching her watch TV and me while I walked past was... odd.

I don't find this creepy at all. All the "personalities" in my brain are just parts of me.

I tend to envisage my mindscape as an orchestra. My consciousness is a fictitious conductor. It doesn't exist, but the lie that it does makes it easier to coordinate things between the instruments. In some manner, by acting on that lie, it is no longer a lie.

In this analogy, when the brain hemispheres are separated, then the orchestra is split in 2. Both develop a conductor, to try and remain functional. Neither conductor is the original me, but neither is not me, at the same time. It would be unpleasant for the variant left unable to communicate however.

I've actually experienced something that felt close to this before. A combination of sensory overload, and panic attack. My mind momentarily became completely discordant. As it sorted itself out, my consciousness reasserted itself in several different loci. In effect, my orchestra had 3 different conductors. It took almost a minute for them to stop pulling against each other and meld into 1 again. I have memories of all 3 sides in the 'battle'.

I know a person who is about to have a corpus callusotomy procedure which is where the halves of the brain are divided surgically, in her case to stop seizures. She is globally delayed and I wonder now what she'll be like afterwards.

Reminds me of the story about the 1956 film The Conqueror. It was shot in Utah, downwind of atmospheric nuclear testing. It was speculated that this caused cancers among the crew.

What the. This is not the kind of theory I came in here expecting to see but you're right it is highly creepy.

What timeline are you from? Evidence of this story?

Fortunately for us, this one isn't too likely, because realistically, an alien civilization capable of travelling the relevant distance and destroying another civilization isn't something that can be hidden from. They should be able, fairly easily, to examine every planet in the galaxy and see which ones have life on them, and wipe it out before any civilization ever arises at all. The fact that we exist at all necessarily implies that nobody in this galaxy has been committed to going this, at least for the past billion years or so.

It's thankfully based on pretty bad game theory. The reality of it is that there end up being more negative consequences to attacking other civilizations than either staying isolated or being friendly, and the proposition is riddled with antropocentric concepts to begin with. Sure, in smaller time scales it might be that alien civilizations would attack each other, but over longer times they would tend to form alliances.

The same argument could be made for each time you go to sleep. That the 'you' that's conscious ends to never exist again and the one that wakes up has all the same memories and body but is no longer the same stream of consciousness that went to sleep, not even knowing it's only minutes old and destined to die within hours.

'You' could have effectively lived and died thousands of times in your life and not even be aware of it.

I mean we're slowly replacing every cell in our body like the ship of Theseus

Oh, wow! It was the ST:TNG episode Second Chances (linked in that article) that got me into thinking about it, and it's really trippy to read that somebody else came up exactly the same thought experiment with a human-replicator, too, and came to the same conclusion that I did: Both the original and the duplicate would have exactly the same memories of entering the replicator, so both would have the same continuous experience of the subjective "I". But if only one existed before replication, where did the second consciousness come from?

After I heard the Radiolab episode, "Loops,", I realized that the only way to resolve the paradox is to figure that our consciousness is re-created more-or-less continuously from our memories. That episode covered the case of a woman who experienced Transient Global Amnesia, which sent her into a loop of about 90 seconds of essentially the same conversation over and over, for hours. There's a famous video of it. That fits with the evidence, from neuroscience, that our consciousness drops out briefly every minute or so while our brains attend to sensory input from the environment.

The COVID-19 pandemic really brought this home to me in a visceral way. In the early weeks, when the CDC was warning about surface contamination, and how I should not touch the mask I had to wear at work under any circumstance, my nose would invariably start to itch. I would tough it out, exercise will power not to scratch the itch, and it would eventually go away. Soon, I realized that I never once got to feel the moment of relief when the itch faded. Always, I would simply notice that it had been gone for some unknown amount of time. It went away with one of those consciousness resets.

So, yeah, like the other folks say, we don't have a continuous conscious experience. The old "I" passes away within seconds, to be replaced by a new "I" with my memories, in a never-ending process of renewal. Think about that next time you walk into another room and forget why you're there.

@Hotspur hey cool you and I just posted about prions at the same time!

If it helps any you wouldn’t see it coming and wouldn’t really feel anything. It would just happen.

Having survived a few suicide attempts I've been convinced this is how it actually is. I have no interest in any further attempts because I know I'll just end up waking up full of regret and possibly maimed.
