Magnifica informacion..
Notice association is practically engulfing the smell part of your brain
im planning to be a neurosurgeon

yes! exam revision on youtube, beautiful!
Hello Youtube,
Everyone who is reading this comment, please click on my username for my videos I made about the The Truth of the World. I have found out what the truth of life is, the truth of the world, and the truth of God. Please, I really want people to watch and listen what I have to say. No more living in false reality, no more living in illusions, no more thinking there is no way out……its time to lead your life into The Truth of the World!!!!!!!!!
I love our Lord!!! God bless!!
Does the brain control you, or do you control the brain?
Is it even possible to favourite on youtube anymore??
saintpin.. yeah thats true what u said thinkin about it, imagine if the brain was able to learn and run by itself would most likly make humans insuperier,
and they say you can find ANYTHING on youtube lol…..
5/5
it’s really really good & usefull
@Spetsop
I’m interested about this subconscious operation of the human brain some year now.
we have under 1000 muscles, but we don’t control them simultaneousness, most probably less the 20 subconsciously.
certain operation are well carved in our memory through practice.
It takes us about a year to learn how to walk and control most of our muscles.
We need a lot of practice to control two hands to play the piano, we do end up doing most operation subconsciously.
@saintpine
And yep, memory does fade, “if you don’t use it, you lose it”… that saying is certainly true for neurons! I haven’t seen a person being able to control 500 parts simultaneously too… but that’s consciously of course. Most of the sensory input that your brain gets from the environment (external and internal), doesn’t even reach your consciousness. It’s either processed and discarded, or acted on reflexively. This is especially true of the internal environment.
@saintpine
Yep, I saw your video. Agree with the point you were trying to make too. As much as the brain does lack in the memory department, that’s not its primary role of course. Most of the cortex is devoted to sensory functions (about 60%, occipital, temporal, parietal lobes), and the rest is organization, decision making, planning, social skills, etc. (40%, frontal lobe). Memory is scattered all over the brain and is composed of more than one part.
@Spetsop
You have studied the brain, I’ve placed a simple video about the memory on my main page to show how ridiculous the memory quality is.
taking images and data is vague, archiving is difficult and not efficient in time it fades out if not refreshed, and recalling data is totally inefficient, data can be corrupted and change due to humor, opinions, convictions and other memories.
the speed is also ridiculously slow.
@Spetsop
I’m working in these days on site on a program in a waste incinerator plant, it has 3 industrial computer known as DCS, it controls about 3000 sensors and runs 90% of the plant, then there are other equipment not under my responsibility.
10% is controlled with a reaction time of 100ms, 20% at 250ms, and 70% with a 500ms reaction time. it’s a similar multitasking operation.
never seem a human control 500 parts simultaneously.
@saintpine
That’s pretty interesting! I’m not as familiar with computers, just know a bit more than the average user out there. I’m a med student, and have studied the brain in university too. It looks like the comp does win in terms of speed. Although, as i mentioned before, some people have extremely interesting abilities, although it comes with a price :(. Well, one thing for sure though, if it wasn’t for the brain, the computer wouldn’t exist either 😛
@Spetsop
I work with industrial automation 23 years now, in the past an industrial computer with the 80286 processor (the same as computers in the early 80’s), could control a process containing 1000 sensors like pressure, temperature, flow, position, etc and about 500 motors, valves, indicators etc.
@Spetsop
The floating point test is just an index, using floating points is more complicated that using integers.
how about trying this simple calculation 52790,213144 + 247812,2321 the best human would take a few seconds to read it, and a few seconds just to pronounce ore write down the answer.
A normal computer could do it trillion times a second.
A computer can run trillions of step by step instructions per second.
@saintpine
Interesting point. Didn’t think the technology was that far advanced already. But, are we talking about number calculations, or sensory processing and decision making as well?
@Spetsop
The brain processes far less information than computer in the 1980’s.
the fastest calculation of even the best human is very slow compared to the computer.
A normal computer today can do any calculation with precision some trillion times per second.
Lookup “FLOPS” on wiki, it will give you an overview of some of the most powerful computer capable of doing 10000 trillion (10pFLOP) floating point operations per second.
the world champion human will never go over 1 per second.
@saintpine
An interesting point, transfer of info from one brain to another can be other than auditory or visual. It’s only experimental now, but it was possible to teach a rat about something it never encountered in its life before, by transferring the proteins from another rat that had the experience already. Memory is stored in a form of proteins, dendritic spines and synapses in the brain, but to get them out, the brain has to be removed, so b/c of that, it’s only experimental for now 😛
@saintpine
I don’t know, I wouldn’t say the brain is very very slow compared to the computer. It processes way more information than a computer does at any time (well the computer of today that is, maybe in another 10-15 years that will change). There are some people who can perform lighting fast calculations with huge numbers, but those are autistic people, so that’s the drawback.
poor girl
@mpd19666 I LOVE that book!! I’m about halfway through. Amazing!
Cherish life.
Every one of us is a living mirical.
hoax ?
That doctor is cool. No, seriously, he really is cool. Like he’s high all the time.
@jayoori1 its 2010
I’m thinking of getting Taub therapy
This is the most impressive thing I’ve seen so far!
@jayoori1 By making that distinction, you are perpetuating racial prejudice. A black neurosurgeon is no different than any other neurosurgeon.
wow! this is simply amazing.
good greif, i can’t imagine losing half my brain. even a corpus collosotomy sounds crazy (chopping the connection between hemispheres). being able to move and without seizure sounds great, but then lacking some forms of higher than normal thinking ability being gone is also almost as scary. hopefully we can move on to further science that works better than deleting parts of the brain.
@jayoori1 Would it make any difference? Not really.
@Xyberfaust I think it’s a trifle too early to see if she can elaborate on Plato’s take on Epistemology
The most fundamental, useful, profitable and encouraging question of all time: What is The underlying law of nature.
im a beginning Psych student and was just curious to see if a split-brain operation would be an alternative. Thanks in advance,
@Xyberfaust thinking is from the front of the brain, not from the right hemisphere.
its not right and left in the brain, its front, back, right,left, and small (spinal cord)
the girl looks fine and not at all frustrated with her limited abilities, it seems she accepts her life was saved because of this small handicap. also, i don’t think any particular retardation would be present but her memory and her simple emotional and calculatory capacity may be cut short
AWESOME!!!!! 😀
Well I know folks or many don’t care thats why we have killed over 50 million babies since 1975 in US but embryonic stem cells are’ntdoing anything they ahve done research and the adult stem cells are what help people. If we say well we just want to kill these embrios because we really don’t care about life then at least someone is being truthful. I am also glad this girl had Carson work on her he is a great guy happened to meet him and he is doing great work. Lets do good not bad
@How4gospel
But those embryonics would not exist unless they were created for the purpose of research. So contemplate that.
But what is also important to know is that its not the evil research you think it is.
OK, she can function and move, but what about her thinking? I’d like to know how it did effect her way of living and thinking. They only gush about her walking and moving but what about the way she thinks? What did it take away when they removed the right hemisphere?
hey sgtsnafu if reagan had half do a brain what do you have zero-if you do your research you will find embryonic stem cells can’t do anything they have tried and tried to no avail however adult stem cells or cord blood do have all types of benefit- please stop the justification of killing unborn children-you don’t have to kill anyone to get adult stem cells you do to get embryonic-be informed
I have recently read this book also (I have no right side vestibular function due to a viral infection). This book has changed my life and I thank Paul Bach-y-Rita (RIP). He is my hero.
Everyone with an IQ over 100 should read the book. It is fascinating.
Ronnie Reagan only had half a brain and that turned to jello before he croaked. Thank God President Obama opened the door for stem cell research!
Not really… the operations works in diferent ways depending on the age of the pacient. From Wikipedia: “Generally, the greater the intellectual capacity of the patient prior to surgery, the greater the decline in function. Most patients end up with mild to severe mental retardation, which is usually already present before surgery.”
