Funny experience: Had a brain surgery in my left temporal lobe. It was swollen and my verbal memory didn’t work at all for 1 week and then just slowly came back First thing after the surgery was me askin my mom how everything went. She asked „how what went?“ I just answered „***** you, the surgery of course!!!“ XDD Later I asked the doc how everything went 3 times in a row. Only on the third time I noticed sth was off… In the week after that I learned my hardest to remember song on piano and solved geometric puzzles while being unable to talk to people because I’d forget what they said half a second later. Aw other funny story: I was sitting at home and suddenly heard music. Song did sound familiar. And there were hands moving in front of me. But they looked strange and I had no idea who they belonged to. Few seconds later I realized I was playing while half knocked down by seizure… Anyways point is: It’s so freakin crazy how independent the parts of the brains are and what happens when you bring them out of balance XD

Consciousness arises at multiple levels of complexity and in various localities of the brain. The consciousness people are accustomed to is the amalgamation of all those consciousnesses. Your experiences arise from the dis-integration of the higher levels of consciousnesses as one does tasks without the others being as aware as they were before. “You” are the manifestation of your prefrontal cortices integrating all the other sub-cortices. Disrupting that integration allows each cortex to operate without the prefrontal cortex’s direct neural connection leaving your prefrontal cortex to experience them indirectly through the visual cortex. Your knowledge of how to play a song is associated to your motor cortex which is able to function independently from your prefrontal cortex. It takes much energy to consciously attend to new ideas like learning new skill. The prefrontal cortex has coordinate all the new actions and thoughts directly. As you repeat the tasks, those actions and ideas build direct connections to each other relieving your prefrontal cortex of coordinating everything so that it can process new variables in the environment. Neurons, at the individual level, are motivated to make connections with other neurons that are active. It is through activations that neurons receive resources, so the more they activate, the more resources they receive. The prefrontal cortex cannot activate multiple neurons all the time, so neurons evolve to connect with one another so that when one activates, the other one does too. At the individual level, neurons are a direct analog to humans. They have to move and learn to code so that they provide value to the community to justify the community providing them resources. Neurons need to do a task to feed. By giving yourself a purpose, you give your neurons purpose. Take care of your neurons, and they will take care of you. If you don’t take care of your neurons, they will still take care of you…that’s what depression is for. 😂 Depression is your neurons trying to figure out which ideas to get rid of by dissolving the neuronal connections that represent them.

@@Ruiluth Oh, it is such fascinating stuff!!! I studied it to fix myself, not to become a neuroscientist. Now my therapist says I should be a post-grad in neuroscience. 😂 I just laughed because I just love sharing how amazing all the little proteins in your body are. Like kinesin are little motor proteins that haul neurotransmitters from the cell body down to the axonal terminals. They take a one hundred 20 nanometer steps every second. Some neurons have axons a meter long: 50 MILLION steps. Scaling that up to humans… and using 3ft per step, that is over 28,000 miles. 😂 INSANE!! But back to another thing I didn’t mention in the original comment: your neurons are constantly processing similar situations over and over again. Everything that is the same from situation to situation will come to be expected. If something changes, the prefrontal cortex has to engage again. So when somebody practices their violin in the fact same room every single day, the visual cortex will come to expect that room as part of the process. When that student performs in a studio for the first time, the visual cortex will begin grabbing the prefrontal cortex saying, “something isn’t right. This isn’t how this is supposed to be.” Because the visual cortex never learned that the practice room was irrelevant to playing the violin, it incorporated the practice room as part of the skill. This is why it is important to vary the irrelevant aspects of a skill so that the various cortices know for sure what is relevant and what isn’t. Playing a violin, the only thing relevant is the sheet music and proper motor processes. Part of being nervous comes from the various cortices scrambling to address all the new information now in conflict with the conditioning they went through when practicing in the exact same place all the time. I would say, the same place initially is good. Once things begin going into the subconscious, that would be the best time to begin varying all the irrelevant factors. Anyhow…I was really excited when you said that it felt like different parts of your brain were talking to each other because that is EXACTLY what they do. Cheers 🍻!!

Given a long enough timespan, evolution absolutely does determine what works "best" for a given environment, because more successful traits will beat out the kin of those with less successful traits, such as intelligence or strength. You'd easily be the best tribe in town if you had those traits. The only reason that you do not see 'the best' traits in every regard is because mutations are inherently random, so naturally there'll be small hang-ups that weren't big enough to truly hinder reproductive fitness.

It doesn't even have to be the one that lives longest or is particularly healthy. I think I remember hearing about an insect or something that only lived long enough to reproduce, and then they just died. It was also only a couple of either days or hours that they lived. The success of certain traits is dependant solely on the organisms ability to reproduce. If it only reproduces once or twice, and has a few offspring, while a competitor reproduced 10 times and has a ton of offspring, then the competitor's genes will become more common in future generations. The insects I mentioned, I don't remember much about them, but I do remember that they suck majorly at surviving. But why and how do they exist then? If they suck at surviving, why didn't they evolve a better method? Because as long as an organism can survive long enough to reproduce, its genes can make it to the next generation. If the carrier of a gene has extra time, it doesn't matter how it uses that time unless it reproduces.

I'm troubled by some of the superlative language in this video. Just because something evolved a certain way doesn't mean that it is the best way. It only means that it is good enough and there is not enough evolutionary pressure to improve, or it may mean that a better solution may exist, but evolution took the wrong track to reach it, or it may mean that a better solution can be reached, but it would involve changes that are deleterious before being able to reach the better solution.

Outstanding. Had never heard the explanation for the transposition of the hemispheres. Fascinating idea. Of course, with evolution, all you need is no good reason for it not to be a certain way, you don't always need a positive selection mechanism. The issue I had with it was that, being in all vertebrates, it was obviously selected early. The early vertibrates weren't on the land and so couldn't have fallen as described and it's still maintained in fish vertibrates to this day.

Yea it's weird. The paper doesn't specify any particular injury to one side, I used falling cause that seemed the most intuitive. But it wouldn't explain fish at all.

But I read a paper with one or two (I didn't save that information in my brain sorry) criticisms of why that explanation doesn't quite make sense. But like you said, because its so early in the evolutionary history there's really no concrete way to be certain.

It has been known about since ancient Greek and the modern understanding dates back to the 19th century from a biologist called Owen who developed the concept of homology; its explanation. Although obviously the science has developed since. Long story short, the science dates back millennia and the modern understanding is centuries old. The fact the evolutionary biologist Dawkins mentioned the giraffe's RLN isn't surprising in the least. It's the biology equivalent of Brian Cox dropping a hammer and feather in a vacuum chamber. This is hundreds of years old established science, which is common knowledge, being demonstrated for the layman. If you think this is bad science, then dissect a giraffe, show the RLN isn't there and publish your findings. Or, if you accept it is there but have a better explanatory framework than homology, then publish a paper in a respected biology journal. Your Nobel Prize awaits.

I have idiopathic hypersomnolence, but later developed some more extreme narcoplepsy. We can experience our mind's awakening, but sometimes our body is not connected. I have also articulated well when woken early in a sleep testing facility, but when told of this, my 'mind' woke up, and was not so able to speak.

@@ButWhySci Meaning can only be derived by distinction. Every process in the brain is a cascade of comparative analysis between variable inputs. The more distinction in the early development of the brain, the more meaning it finds later in life. Also, neurons have to maintain connections to active networks, so if distinctions are not provided early in life, pruning will leave the brain unable to perceive as many distinctions later. When a baby is “distracted,” it is because the brain is evolving to represent the world around them. Consciousness is virtualized reality, and that’s what neurons do to find purpose early on. Once formation of neural nets from experience peaks, the brain shifts to understanding the relationships between those crystallized ideas. This is why baby mobiles are extremely important. As the baby experiences multiple samples of a scene (knowledge), it can reconcile certain related areas from each scene as a single object (understanding). Initially, an object viewed from different perspectives is not understood as the same object until proper synaptic pruning occurs. Experience > associate Knowledge > Understanding The main difference between neurons grouping to represent an idea and magnetic bits on a platter grouped to represent an idea is that neurons are living organisms that can freely explore the spaces between ideas. This is the basis for inspiration and synthesis.

Because we are a duality There is no greater challenge in life than discovering both sides
