I am trying to find out some information about the nerves that deliver sensory inputs into the brain. I understand that neurons in the brain itself share thousands of connections to other neurons. The neurons that deliver sensory information into the brain at some point meet the ones in the...

Brain Teaser #4?? What is the explanation. It seems totally incorrect. If the son is going to stay 123 weeks - and each week he HAS TO break off new links. Then he MUST break off something each of the 123 weeks. Explain the question...

I guess I don't have access to the brain teaser forum. This one kinda confused me: Using “Only Four” ZEROS (0) and any Mathematical Operations/Symbols, to obtain the number 24. Answer is (0! + 0! + 0! + 0!)! = 24 I know I am a bit rusty with hex/binary arithmatic but the answer i...

Greetings ! What's all that stuff about (0! + 0! + 0! + 0!)! = 24 !? Thanks ! :smile: Live long and prosper.

I took this from another board I posted on. Noone could really answer much of it. Please no debate about what intelligence is. I couldn't find a neuroscience message board, but I have some questions, so I'm hoping someone can answer them here. What exactly makes one intelligent. Is it the...

I don't know if this necessarily belongs in the philosophy section, but we'll try it on for size. So as you all know, we use maybe 10 percent of our brain's capacity(some use considerably less, but that's another topic:wink:). Einstein purportedly used maybe 20% of his brain(this may be an...

Some years earlier I read a book about brain enhancment, and of the many substances tested, it seemed that intake of nicotine had been the only one that actually IMPROVED test scores. Caffiene, one of the other substances tested, was not useful in this respect nor were many of the things...

When we percieve objects through vision, our visual cortex is involved in processing the information. When we dream, I think it is also working. But what about when we imagine geometric objects that aren't really there? If I were to start thinking about an object from my memory, would the visual...

I've begun taking a herbal dietary supplement that claims increased memory capability and other such enhancements to brain functions. I read somewhere that they are not effective, however, I have noticed a distinct change, one that I believe may validate some of the supplement's claims: I...

From the Marrium webster online dictionary brain> 1 a : the portion of the vertebrate central nervous system that constitutes the organ of thought and neural coordination, includes all the higher nervous centers receiving stimuli from the sense organs and interpreting and correlating them to...

What kind of electricity does our brain use? direct current or alternating current?

Here is a favorite of mine from college that I thought you might enjoy: Consider a closed square loop of wire with two resistors, R1 and R2, each located in-line and symmetric about the center of the loop. Two voltmeters each measure the voltage change, V1 and V2, across R1 and R2 respectively...

"The hyperstructure of the brain" I found this discussion on the Mkaku.org community. It is very...different and I wanted to know what pf members thought about it. Believe me, its a very interesting idea: http://www.mkaku.org/forums/showthread.php?s=&threadid=230

[SOLVED] A discussion about the brain. If there is no such thing as 'purpose' in the whole universe, then how can we say that the universe has bestowed us with our own sense of purpose? We have purpose in life. Even if that purpose is just to stay alive and enjoy life. So where does this...

is there any kind of studies done on people who use one half of the brain more then the other and some of the differences in personality characteristics? for example: one of the first things i note about people i meet is what hand they dominantly use, and if it is the left hand, it seems...

My Biology teacher had recently said that we actually use only like 4-5% of our brain capacity. Is she correct?[?] I think that we are using close to or 100% of our brain capacity. Because the brain uses the highest amount of energy in our body, so i doubt that evolution of such a big brain...

The other day i came across [Removed Broken Link], and while reading it i started thinking; "Why don't we human try to compress the things we learn before learning them, and uncompress them when we need to remember them ?". Then i realized that the human brain finds it easier to memorize a...
