A brain tumor was recently experienced. It was on the surface tissue of the brain and was about 3 inches in diameter. Non cancerous. There was no reported brain damage. Everything healed up great. For a good month or two, way of thinking was altared a little. Presently that way of thinking is...

Our brians are made out of organic material. It is very likely that the macro features we have such as consciousness, mind, qualia etc are an emergent property from these complex physical properties. But could these emergent properties come from an extremely complicated device that is not...

The following statement is true: 12=11 There are no mathematical operators (+, −, *, /), exponents, parentheses, etc. missing. How can 12 and 11 be equal? Hint 1: The given is not false. Hint 2: How did the first humans count?

Where The Brain Combines What's Heard And Felt When sense perceptions from various sense organs are processed in the brain, this information is integrated - for example, when we are watching a ventriloquist, our brain combines information pertaining to both language and vision. Using functional...

Is the brain's perception of space trained or is it ingrained and locked to 3? That is, would a baby raised in a 4 *evident* space dimensional world be able to adapt or only cope?

I know nothing about this science, but i was on mushrooms the other night and came up with an idea.. I've seen scans done on the discovery channel on the brain during certain thought processes. If you were to show a screen of red, compared to a screen of yellow to the subject, would...

Q: A solid if formed by adjoining two hemispheres to the ends of a right circular cylinder. The total volume of the solid is 12 cm^3. Find the radius of the cylinder that produces the minimum surface area. OK, I got about halfway through my problem before I got lost. V of shpere= 4/3(pi)r^3...

I recently heard about brain wave . Where can I find the explanation on brain wave ?

Is it possible to move ones own consciousness inside the brain? For example is it possible to move it to the left or right a little bit, or to the back, or even down the brainstem?

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...

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?

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.
