more can't turn the brain into a computational process! Firstly, I apologize for being so against the computational idea, but my idea about the little man in the head looking up ideas in a library in the head ad infinitum kept nagging at me and suggesting to me there was something there. It...

hi guys. was wondering if human brain is effected when it is in a magnetic field. cheers

Has anyone heard of the IBB? I think I might participate in it seriously, and if so, I'm going to need some assistance on what to study, how to go about it, and maybe even a mentor that I could talk to ;P Basically this is a contest about neurology, and all stuff relating to the brain. A...

What part of the brain is involved in turning thoughts and ideas into verbal communication, and why are some people able to communicate their thoughts easily and fluently while others become tongue tied and find it difficult to put their thoughts into words?

Hi, I'm new to PF. So here goes... If i get a new game, i usually play if a lot (since it's new and all). I probably play it late. That night though, i get a lot of trouble sleeping. I keep waking up (sleep walking, or some form of that) and i'll have my hands infront of me thinking...

Breaking news; see this NY Times story. Two separate genes for brain size have been shown to have developed rapidly in recent times under selection, one since -37,000 (Cro-Magnon era), the other since only -5300 (neolithic, just before writing invented). The papers describing the research are...

There's a boat to cross a river, and it can carry 2 people at once. There are 3 cannibals and 3, well, regular people on one side of the river. They want to get across. If there are more cannibals on one side than regular people, you lose. The boat cannot travel empty. Have fun! :biggrin:

Has anyone Benjamin Libet's work on free will (http://en.wikipedia.org/wiki/Benjamin_Libet is a brief summary). Does anyone know of any objections to why his work does not suggest that all behavior is brain based. Does it seem really weird to anyone one else that all this I/ you are doing could...

perhaps I'll get more replies here "explain how liquid water can go from 25C/1 atm to 30C/1 atm in a process for which q<0" I was thinking perhaps that since , q=mc_p \Delta T how can q be negative when the temperature change is positive? , maybe it has something to do with the specific...

The 15 July 2005 issue of Science has an interesting article regarding something called anosognosia. It seems very strange that one is unaware of their own paralysis while they are completely aware of the person they are being interviewed by asking them about it. The patient in this case...

My friend was saying that *it is only physically possiable for the average human to use 10% of their brain at once. (She wasn't saying we always use the same 10% of our brain though) Is that true?

High-Resolution Brain Atlases in CyberSpace (I-Newswire) - After a long decade of the U.S. sponsored Human Brain Project, we still have not advanced our understanding of brain structure and function very far. In particular, the availability of online high-resolution brain atlases has been...

Take a long rectangular piece of paper, and tie a simple knot. Carefully pull it into place and the location of the knot will be a perfect pentagon. Why? (Not a brain teaser, I really don't know the answer.)

I posted this in the Brain Teasers forum, but nobody's really taking a stab at it. It is more mathematical than a brain teaser. This is not homework; hope it's all right posting the link here. https://www.physicsforums.com/showthread.php?p=609930

The parents insisted an autopsy be performed on their daughter and the results show that the husband was right all along. Even with the results showing she was blind and in a permanent vegetative state with no chance to improve, her parents remain in denial of the truth. "An autopsy on...

Are they any kind fun math brain twister books that are restricted to calculus (up to sequences) and require engaging algebra manipulation and forethought? Can anyone suggest such a book?

This isn't a book review, so forgive me if I'm posting it in the wrong place. o:) Anyways, I am looking for some reccomendations on books about how the human brain works... consciousness, subconciousness, dreams, memories, telekenesis, recent research findings, etc. I don't want anything...

OK, forget the Sistine Brain... What's this?? Surely some symbolism here?

This painting is being used for the cover of my behavioral neuroscience text for the reasons mentioned at this link: http://www.thecaveonline.com/APEH/michelangelosbrain.html I am sure it is all purely coincidental but it is still fun to look at.

The body is essentially the powerhouse of the brain right? Do you think we could use robotic- non-biological- bodies to power our brains? Because I keep on hearing about how people can have electrodes implanted in their brain that will allow them to see and hear and feel etc. And I read...

If you wanted to, how could you preserve the brain? I mean other than cryogenically?

Some people develop Alzheimer's disease after a blow to the head. Has physical damage been done to nerve cell apparatus e.g the endoplasmic reticulum,Golgi apparatus,by the pressure of a blow to the head?

Is fatal degenerative brain disease inevitable? If we could transplant ourselves into clones every 20 years or something like that, how long would we be able to live before degenerative brain disease, or something like that, killed us?

I'm attaching this here (hope that's ok) because the brain teaser forum is unmoderated. Anyone who's interested, the brainteaser this relates to is "cursive letters."

if 1*2=2*1 2*3=2*1+2*2 3*4=2*1+2*2+2*3 4*5=2*1+2*2+2*3+2*4 then 3*1+3*2+3*3+3*4=?

This one is probably very difficult: 101110111110111101100011001110111? What fills in the question marks?

I have been thinking for the past week on how the mind works, and classical physics theory has plenty of holes in it. The most convincing aspect of my new theory is with how the brain and memory work. When you wish to remember something, could the brain and its neurons be sending an advance...

Many physical constant can be expressed in terms of Energy, Time [T] and Distance [L]. Now some basic qestions for a brain storming session. 1. if acceleration is L/T^2 then what name would you give the next term L/T^3 ? 2. if the speed of light is the maximum speed is there also a...

This was in a maths textbook. An arrow approaches its mark, (where its supposed to hit) but as it approaches closer and closer, it will approach half the distance it was at some time ago away from the target, and so on and so on and so on.. So I am asking: Why does the arrow ever reach...
