I hope you don't mean that literally, because that is really wrong. The sperm cell is [URL="https://en.wikipedia.org/wiki/Human_fertilization#Fusion"]completely disintegrated[/URL] and fused with the egg cell.

Obviously it's a combination and a ton more complicated than I have any clue about, but I think it's probably closer to being the opposite of what you just said. You are the internal voice, the left brain, in charge of making sense of and attempting to direct all the ridiculous emotional decisions we make with the right brain.
[QUOTE=Zang-Pog;51252401]I think some doctor in Russia is going to do a head transplant for some guy who had something wrong with his body onto a donated body that's braindead.
I don't think our medical technology is quite there yet, but if they actually go through it and make it work it could mean big things[/QUOTE]
For some reason the term "head transplant" really confuses some people. They assume that if they get their head swapped they're still going to be the same person, but with a different head...which makes no sense.
I guess it would be more accurate to call it a body transplant but regardless, it would be pretty interesting if the operation you're referencing doesn't fail horribly.

So what you're telling me is that the weird shit I've fapped to is left brain being tricked by the impulses of right brain? Unless it was a collaboration...fuck.

The biggest issue as previously mentioned is making sure the transplant candidate has full functionality of his new body, the second is making sure rejection doesn't take place.

Unless both brains are split they are working in conjunction with each other, basically you split the brain and the usual connection that keeps everything whole is also broken which is what allows the part of your brain that can't talk to go out of sync.
So technically no, unless you get the proceeding medical procedure down the line both half of your brains are working in sync with one another so much that they might as well be one whole.

The brain looks so soft and delicate that it makes me wonder if you could scoop a piece out and spread it on a slice of toast, or if it gains a firmer texture from frying. It reminds me of minced meat, McKuru, anyone?
I am a brain not only watching someone handle a brain, but i'm also aware that it is a similar brain to mine.

Your nervous system is actually a bit more complicated. For example, your heart actually has some nervous tissue in it, which may do more than we think. For instance, some people after they have a heart transplant show radically different personality or unexpected life changes.

It's really safe but honestly I don't get why you'd spend $300 just to look a bit more fashionable. A normal helmet will do the job and it won't "break" just because you forget to turn it off (or not pop when it supposed to because you forgot to turn it on). To each his own I guess.

I'd like to see a source on that. The heart itself doesn't (to my knowledge) include any nervous tissue - the sinus node generates electrical impulses to keep the rhythm, but I haven't heard anyone refer to that as nervous tissue; I'd guess they have more in common with muscle tissue.
Also a side note - I'm pretty sure the brain is also propped up by the CSF through osmosis, which results in it being more propped up when inside your head compared to the video. Maybe I'm wrong, though, it's been a while since I had (very much introductory) lessons about the brain. Starting up on CNS in a few weeks, though.
I think you are your whole body, not just the brain. The body is a massively complicated chemical processor and it's state affects how the brain works (not just what you sense, but it also affects your emotions and level of alertness, not to mention the performance of your brain (due to your body being the supplier for the brain)). I kinda feel like something that has such global effect on all of brain activity has every right to be called a part of me.

the cardiac nerves, including the conduction system, are part of the ANS, or autonomic nervous system. The cardiac plexus is located near the base of the heart, and it also receives supply from the vagus nerve, which controls heart rate as part of the sympathetic nervous system. That's why a denervated heart (in transplant patients or those with a damaged vagus nerve) does not speed up or slow down in the event of a fight or flight reaction.
The conduction system of the heart is, as you mentioned, composed of cardiac muscle cells specialized for that purpose and richly supplied with nerve fibres, from T 1-4 and the vagus nerve.
Man all this talk about cutting the corpus callosum, split brains and just watching the OP video sent me into Fight/Flight.
I'm half tempted to wrap my head/neck in bubble wrap and a kevlar helmet now. :tinfoil:
Real talk though, what's the speed of a neuron signal down a mylenatied axon? If its slower than the speed of electricity then it is theoretically sound that we could implement a neuron cluster on proper hardware.

Yeah sure - I was just talking about what he might've thought of as "nervous tissue in the heart"; the nerves innervating it are hardly part of it, at least the way I'd put it.
Edit: To be more clear, I was asking about sources on the personality changes being related to the innervation of the heart. Losing (para-)sympathetic impulses to your heart may change how you experience moments (heart beating during your first kiss or whatever), I don't know, but on a deep level? I'd be a little sceptical.

[QUOTE=Trebgarta;51253499]the ratio of myelanted/non is like 10/1 but I am not sure the precise speed. I guess like 100 meters per second versus 10.
[editline]24th October 2016[/editline]
Of course it is slower than electricty, it is a bunch of chemicals versus literal electrons.[/QUOTE]
the speed for myelinated neurons can reach 120 m/s to be exact. Also it'll never be faster than electricity, which varies in speed from 50-99% of that of light.
so whoever's brain was that had a stroke i assume?

Currently this is pretty much considered pseudoscientific and unsubstantiable, for what it's worth (personality changes after heart transplant). Some individuals have published case studies, but they tend to fall under the category of false memory syndrome (the memory is factually incorrect but they strongly believe in it's truth.) However, FMS is not a psychiatric illness, indeed, not even categorized in the DSM or ICD. The syndrome's diagnosed when people are so ingrained in the belief of this false memory or memories that people refuse to face evidence of the falsity of this memory.

looking at and handling a human brain in person is even weirder and more humbling
Saying that we are our brain is a little bit misleading. We are our brain combined with our body. Physical action and sensory experiences together actually form cognitive "states" in the brain, embodied memory essentially. These embodied memories are essentially metaphors created by correlating bodily sensations and mental processes. These metaphors can be engaged, which is why art and images, or smells, sounds, etc. can actually "bring you back" to a moment; the brain is actually RECREATING the space mentally, to the point where you can almost feel it bodily. This is a useful tool for the brain because it allows it to easily process a space if you have lots of habitual physical experience with it, it takes up less of your conscious attention and uses less mental resources. However, it is a useful tool for artists and designers too, because we can manipulate it to provoke bodily responses within people that engage our craft. Similar to muscle memory, but for the body / senses.
