Isn't the main difference between a computer and the human brain this: a computer uses a programme to process data but the human brain processes data and processes programmes which process data (to improve the data processing programmes and thus increase the brain's effectiveness and...

The brain is supposed to be the most sophisticated piece of electronics. It can do things we can't dream with our current computers. I want t know how many of the worlds most sophiticated computers would it take to equal the output of our brain proccesing. Is our extreme computational power...

I am working on a paper about dyslexia. It is interesting to me that, on the one hand, dyslexia is labeled as a disability or deficit, or a glitch in the brain. But on the other hand, data shows that these same kids have above average IQ. How can the brain be both - disabled and above...

Hi, There seems to be lots of interesting news about Brain Computer Interface recently (and not so recently).. for example artificial vision (even if only a handful of pixels) and controling prosthetics.. also some interesting articles on rat-neuron computer chips etc. What I find most...

Does memorising improve your thinking abilities? I think that problem solving is the best way but would spending a little bit of time memorising things that you find interesting and may prove to be useful in the future be a good thing to do? Or Would it tarnish your creative thinking...

Hello all, I am doing a high-school grade science fair on the effects of aging on synesthesia. Well, at least that's what it tests, but in reality, it's the other way around, almost. Synesthesia, while, indeed, being a genetic condition, is a condition of the brain. Therefore, if the brain is...

The aim of the game is simple (similar to the Math Q&A game). I will post a brain teaser, the first person to give the correct answer gets to set the next question, the first person to then answer this question correctly gets to set the following question... ad infinitum. A few rules before we...

I have selected a few brain teasers at random for the most part that I found at least mildly amusing and that I could not immediately find in this sub-forum. I wouldn't say that any of them are very hard, but some require sideways thinking and I think that makes them fun to do. It is almost...

Here's how these work; 26=L in the A would be 26 letters in the alphabet, 12=N on a C would be 12 numbers on a Clock, and 1=the L N would be 1 the lonliest number. Here they are; 10=A by L Z 273=D K in Z D C

My question is about West Nile Virus and why/how it is much more likely to cause encephalitis in the elderly. What I've found is that increased permeability of the BBB is what allows the virus to infect brain tissue which is how the majority of neurological damage is done. The rest of the...

Well i have done it, and now i feel very low, sort of having no more to offer, not that what i offered had any value any way, it is just a rotten feeling, that one is useless.

Just wondering...does anyone here have any infomation to share on brain imprinting? such as transfering memories and thoughts from one person to another?

Answer selects two natural numbers from the range [2,100] (x, y). He tells one man Sum' 's' (where s = x+y) and another man 'Product' 'p' (where p = x*y). The men are asked to find x and y. Both men have perfect logic. Know that the starting numbers were selected from [2,100] And are good...

There's a common belief that every glass of alcohol you drink kills a certain number of brain cells. This is a myth I thought I'd clear up here, one that results from a severe condition sometimes seen in chronic alcoholics called Wernicke-Korsakov's Syndrome...

Seriously, it seems like the cannabis plant is built for the intelligent, inquisitive, imaginative, ect. mind. Not only do my senses, reason, intuition, and imagination expand on marijuana, I also understand science so much more. There is something it does to your logical faculty that makes you...

i tried searching for it on google but couldn't get the right term. Do you guys know of any research going on trying to transfer knowledge directly into brain like chip?

I just started physics this year, and we were assigned our first problem today. Before I continue I'd just like to stress that I am not looking for an answer. Just a hint, or something to help me out. Telling me that I'm on the right path would be helpful as well :smile: Here's the...

is palpitation related to our brain?

I am taking too many AP classes plus I am in a chess club. Now what happens is that even though I have an A so far in all of my subjects. I can't get rest. Literally, I study till my mind starts burning, then when it gets really hot, I jump in the swimming pool for half an hour, then study...

I've been hearing that our very brains have more computing power than the highest of computers. IS this true. I mean what do we d o that's all that complex without brains. I know consciously we don't have very much math ability but unconsciously we do. By the way, which mental activities use the...

I am reading an article in this month's SciAm mind about treating depression with deep-brain stimulation. Researchers found that an area known as Area 25 is overactive in patients with severe depression. From what I understand, this area is sort of a "traffic controller" for neural paths between...

This one should be quick and easy, but I just can't seem to get it: "A college rower can easily push a small car along a flat road, but she cannot lift the car in the air. Since the mass of the car is constant, how can you explain this discrepancy?" Edit: I'm thinking that friction can be...

This thread is nearly dead. :zzz: I urge you all to post any new brain teasers you have or any website on them. Come on, we need some fuel for our empty brains. PS: I have a website. www.mindsport.org

Hi, I get my grad school decision in about 2 weeks.:cry: I'm having a problem deciding between 2 fields that I would love to do a research project in. Both involve Computational/Simulations Science [Computer Science(computability and 3D engine development) & Mathematics]. The 1st is...

I am working on a repair for an old Meriam Well-type manometer and I am being a bit lazy on thinking/writing out my problem. I am trying to design a new well for it. My question is -- am I right in thinking the well should have a large diameter and a low height so that the fluid pressure...

Okay, you're in a game show that is akin to Deal or No Deal. You are given 3 suitcases to choose from, 1 of which contains a million dollars, the other two are empty. Once you have chosen a suitcase, the host (who knows beforehand which of the 3 suitcases contain the million dollars), opens one...

Hello, I'm wondering whether heavy electromagnetic stimulations of neurons can cause our brain to stop working at all, in sense that all the neurons stop receiving the messages from any other. Are there any known hypothesis how our brain could be possibly made during an evolution? And Does the...
