Hello guys, when blood vessels going to brain are constricted, there is less blood flow and less 02 and CO2 entering the blood vessels in the brain. How does this create hypercapnea (too much CO2), is all the 02 that comes in extracted and turned to carbon dioxide which causes this. Also this...

Im not sure if anybody here can answer this, but, this is my question What negative health effects etc can occur from viral gene therapy being used on a human brain (to add one or more extra copies of a gene) what are the odds of those negative effects occurring in the person from viral...

Hi I originally posted this at yahoo ans but I guess I may get ans. from professionals here. source yahoo ans:http://answers.yahoo.com/question/index;_ylt=Ap2AfVLWOotPnuPOPzw6GfYazKIX;_ylv=3?qid=20100207115304AA4Du5m

I know this is a dumb question but dumb questions are easier to fix than dumb mistakes so here goes. Is 2x(x)= 3x or 2x(x) = 2x^2

Nano magnetite particles are found in the brain. They are associated with schizophrenia, parkinson's disease, aging and etc. Imagine that we are able to make a huge NMR machine and place a live human being in the bore to cause levitation. The diamagnetic particles will orient against the...

Hi all, I am curious about the effect of long term drawing/sketching/painting on the brain. Is there any serious work being done on this topic? Would be good if someone direct me to some journal articles on this. Thanks

The trick is to see this lady spinning in each direction: clockwise or counterclockwise. Most will see it orienting in one direction only. It's difficult to switch it in our minds. For many the task will be impossible. http://mindbluff.com/clockwise.htm

Now I'm sure many of you have heard that it's easier to perform certain tasks when listening to music and etc. I was always a bit unsure about this because I'm someone who doesn't listen to music often and I prefer silence for when I study or read. What do you guys think about music and its...

Term Paper: "Is the brain immunologically privileged?" I have to write a term paper for my neuroscience class and the theme is "Is the brain immunologically privileged?". According to my professor I have a pretty nice introduction that explains the anatomical aspects of the brain that makes it...

Hello, I am having a little problem at the moment. I am working in a library, have been here for 5 hours now and I am losing focus, for example I read a paragraph 3 or 4 times and did not digest any of the information at all. So I think I need a break. The challenge is, if I get up I will...

Are there any pharmaceuticals which improve normal brain functioning over the long term?

I started this thread for the discussion of the consequences of our knowledge of physical determinism/probabilism on consciousness. What are your viewpoints regarding what I think are two possible scenarios: a. Consciousness can be solely attributed to the physical brain (it is a physical...

Okay, here goes. The first one to figure it out will receive an HTML code in their email address (please give me yours when you answer) that is a virtual pet.:smile: Good luck! *** A man is coming from Switzerland on a train after his successful eye surgery. His eyesight was still poor, so if...

Hello everyone. I have become very interested in how the brain works recently. I know that in sleep, your brain is basically going through all of the information that it has obtained, and sorts through it (decides what is/is not important, and strengthens/weakens those connections). But...

Is there a consensus on the current theory of the brain that can be agreed on by neurologists and psychologists alike? Perhaps even philosophers (real ones that acknowledge physical sciences). The philosopher I like a lot is Daniel Dennett. He rejects the...

Not sure if this is the best spot for this, but thought it might be of interest to some folks here. Free seminar open to the public. Where: Lehigh University, Bethlehem, PA Date: Thursday, September 24, 2009 Time: 4:10 PM Loc: Iacocca Hall, B-023; Mountaintop Campus Host...

The other day, I was sitting down watching TV, then I turned the TV off, and the DTV, and I noticed a sort of ringing high frequency humming in my brain. But the strange part was that when I turned my head 90 degrees, it stopped or got really quiet. Turned my had back to normal position sound...

I've been trying to find some very specific information about the workings of the Human Brain. I've tried going through Wikipedia reading about each part, but many of the terms are confusing (I'm obviously not an expert) and they aren't organized in any way which is helpful to me. I've...

I've tried googling and using google scholar, but to no avail? I'm especially interested about avian (bird) brain masses. Thanks!

Homework Statement Driving to a nearby city, a motorist estimates his travel time, considering that he can maintain a constant velocity of 90km/h. Surprised by an unexpected rain shower, he decides to reduce his velocity to 60km/h until it stops raining 15 minutes later, at which time he...

http://www.centreforthemind.com/publications/IntegerArithmetic.cfm So, if you can do something that does not violate the laws of physics, but it is something that other (highly qualified, highly experienced) people cannot even remotely replicate, it is still not proof of paranormal abilities.

I ran across this interesting article. http://news.bbc.co.uk/2/hi/technology/8164060.stm EDIT: I think the tech writer got something wrong when he wrote 1 laptop=1 neuron in terms of Hz at least. I really don't what was meant by that. A 10,000 neuron network might work for a snail. If...

Homework Statement The question is thus: e = even digit o = odd digit eo x ee ----- eoe +eoe ----- oooe Which is just the expanded multiplication of the numbers eo and ee, with eoe and eoe being the partial products and oooe being the product. The question is to find...

Homework Statement Integral Sqrt[16-x^2]*x dx from 0 to 2. Homework Equations The Attempt at a Solution First thing I do is a u-sub, so u=16-x^2 du=-2xdx I also my bounds change to upper=12 lower=16. After I integrate and swap out my U, I get -1/3*(16-x^2)^(3/2)...

I was always curious on this one. What part of brain do we use for solving physics problems?

I've been working on learning c++ pre-emptive to going to college. I've found that I've come to learn it really well off of youtube videos. Unfortunatly there is no youtube series spanning the variety of fields in c++ that i need to learn. I read too fast and find myself reading right into...

this is how I was told At a party, each person knows exactly 22 others. For any pair of people (X & Y) who knew one another, there was no other person at the party that they both knew. For any pair of people, X and Y, who did not know one another, there were exactly 6 other people that...

this may not be the right forum, but I guessed so, reading the thread posted by Rex S titled as “Can there be Artificial Consciousness and Emotion? ” reminds me of an article I read last year, it was about heart transplant, I was thinking of it a couple of weeks ago, and thought I would’ve post...

Hi physics geniuses! I've been awake all night (grr!) trying to figure out some stuff we talked about in our calculus-based physics class today about Relativity. I hope you guys can make this all clear to me, because maybe then I can get some sleep! OK, so our professor told us this week...

Is the neocortex a layer of the cerebral cortex? Also is the neocortex restricted to the cerebrum or does it extend into the cerebellum too? I read a few different websites and they didn't give consistent explanations. One site said the neocortex and the cerebral cortex are the same thing...

We all know and love these guys. But they seem so trivial after you solve one. Even if you've solved it ages ago, that formula is still inherent in you somehow and you can bring it up (like bike riding). So when I saw: I automatically went and searched for that file in my brain. Post your...

Ventricles in the brain... why? I am watching a TTC video on the brain and it mentioned that the brain has (as far as I've seen so far) 5 different ventricles (cavities) inside it. I was wondering about why the brain would have spaces in it considering how complex it is, why should it give...

A five-part NPR series about the science of spirituality: http://www.npr.org/news/specials/2009/brain/ Note that any specific and controversial scientific claim discussed requires a published paper or an appropriate scientific reference. Otherwise it must be treated as anecdotal evidence.

http://www.nature.com/nature/journal/v446/n7138/abs/nature05631.html Very interesting article. I'm not proud of being an utilitarian anymore.

Why does the cerebral cortex require a large surface area (demonstrated by the large number of folds and creases in it)? Surely the brain simply requires as big a volume as possible, to fit in more cells, as there is nothing outside the brain it needs to interact with.

there was some thing on the news not long ago and i would like to find out what has happened in this field folks are takeing med that tho made for some other condition are enhanceing their abbility to thing better and be more on "their game" then normal and that the military has also been...

Has anyone tried doing it or has done it? Do you think it will be possible to interface the human brain with a computer some day?

Is is possible to quantify how much "space" a human brain has? Kind of like in terms of hard-drive space? I am sure this depends on the person.

Lets assume that the brain is you - it is all your thoughts, feelings, experiences, 'soul' stored within the many different combinations of neurons. Now since these connections between neurons cause a person to be then a machine capable of creating a humans neural pathways randomly would...
