Brain intelligence

Postby manish94 » Sat Apr 30, 2011 1:13 pm

In my class, lecture was going on topic brain..he said that the brain intelligence depends upon number of cells that are present in inner brain surface that is below piamater. The greater number of cells are their, the greater is intelligence. To increase capacity for cells, brain develops inner folds and depressions, that leads to increase in capacity and number of cells. And he said that almost all people have same number of folds and depressions and same number of cells...so my question is what are the other reasons that are responsible for loss or gain of intelligence?? :?: :?:

Pretty big can of beans you opening. You first have to decide what 'intelligence' is. IQ tests these days (Stamford-Binet) use all sorts of reasoning - verbal, spatial, numerical - but older ones tended to focus on mental agility and reflex times etc. Now there are arguments for including imagination and creative thinking. I think it would be safe to say there are at least a few different kinds of intelligence and you're unlikely to be score highly in all of them!

It's been postulated that each new synaptic connection between neurons leads to a new concept, leading towards thoughts. In this case the greater the number of cells the greater the mental ability. We all broadly share the same features (like the various regions of the brain, and the structure of the homonculus) unless developmental errors or strokes have damaged it, and so far other than obvious mechanical damage there is nothing to suggest why we think they way we do. The brain's too complicated and misunderstood to give us this sort of information.

I imagine what you're lecturer was referring to is our brain compared with, say, that of the great apes or other animals. We do have a far more convoluted and advanced brain than theirs because we've branched out into many new skills - like creative art and complicated vocal signals - that they haven't. Our brain is a lot more contoured than theirs. But trying to answer what makes each person's intelligence different is a task that would be probably get you a Nobel Prize!

thank you for that..and he was not comparing with any animal brain..but what i wanted to know that i didn't got..some are more intelligent than others..and some have less mentle ability to think, to remember etc...so what's the reason for this?
if anyone can answer this?

you have to understand what earth wants from you if you are to be a scientist then your brain will be chosen before you are born its all in the name of gods art the world cant change we was programed from the begining we think we can beat god yet it is a program that is in tune with our minds that god changes now and then who is god or what is god probualy a group of atoms would be my guess my best advise would be keep your head down dont try and stand out and be content with what life you have been given i stuck my head out and got shown the worlds play if only i could of been content with my life and been left alone what a happy world i would of lived in

I think the quick and rough way of guessing intelligence in animals is a ratio between the mass of the body and brain. But this isn't too accurate, its just a fast way to make an assumption without a lot of data.
