How many gigs is the human brain?

I know you were joking but...

The brain is estimated to process 10^7 to 10^10 chemical reactions per second. If one chemical reaction equals one floating point operation, that's 10 MFLOPS - 10 TFLOPS.

Maybe you need 10 PS3 Cells to get the same power as a human brain (but they spend much more energy than your brain and are much more noisy).

Haha me and my friend use to joke about slow people's brains making that searching noise that older hdd and floppy drives use to make back in the 80s and 90s

so there is no maximum?

Well if you are talking TV screens... then you should use that chart posted in the first link.

Basically it is saying if you view your TV from 10 feet away,(a normal distance I would guess) you need at least a 34 inch TV to notice anything better than 480p, and a 50inch TV to notice anything better than 720p, and a 77 inch TV to ntice better than 1080p.

If you view your TV closer, say 5 feet (I doubt many view TVs closer than this)... you need a 25 inch TV to notice better than 720p, and 39 inches to notice better than 1080p.

To be honest 5 feet from your TV is a very 'bedroom TV' distance, ie unlikely to be a big TV.

The Cell 3 will be actual cells!

Most people here are right. How detailed we see something depends on the distanced this is also true of Cameras the farther something is the lesser the detail. It is all about the angular diamater also known as how large something appears.

In a picture or video a pixel represents so many arc seconds that arc second could represent 1000th of an inch 2 feet 8 miles or 5 light years depending on the distance hence when you take a picture of the moon it appears small upping the rez allows for greater detail because you get smaller arc seconds.

The eye does the same thing. It can even suffer from things like chroma abberations blurring when the aperture(iris) gets to small but only if you get screwed up the eye switches from cones to rods.

You have more rods than coens in your eyes. The cones see color the rods see B & W. The brain then takes information from these sources and compiles it in the brain elimination duplicative information and adjusting(Your eyes have to cameras and while you see only one monitor in front of you they actually have a different angle you brain throughs out junk so that you only recognize one and thus can function

Oer eyes have approximately 5-7 million cones and 100-120 million rods. As you can see the resolution at which the eye can see is very edependent on the situation and how much light there is. I am not sure but I do think both are active at the same time and that the brain takes info from the cones and uses it to upscale the B&W infor the rods to color. If that sounds bizarre to you think abotu this when you take a picture with digtal camera or a video doesn't matter. The camera DOES not record in color. It records in monochrome 3 times. Each of the sperate images contain pixels and each of these images contain pixel information that can be 0-255 or 8 bit but when you apply all three you know have 3 sets of 0-255 that correspond to the same image the computer than takes these monochrome images and translate them to color and voila you have a 24 bit image.

So to answer your question around 110 megapixels but all the way up to 125 megapixels but ny images you see rapidly lose their detail because of angular diameter so a TV with even half that rez woudl still be over kill for resolution.


I hope this helps a little.



The question is a digital player in an analog world. More specifically its the modern equivalent of a zen riddle. There is no satisfactory answer its goal is to sweep one into a form of circular reasoning. The question is meant not to be answered. All I can say is that the eye sees everything in complete fidelity within the visible spectrum of light.

We cannot determine how much data is processed, or in what context it is processed. Scientists have yet to determine how consciousness intersects with raw data. They however know that the brain does not process data with true fidelity. The brain discards irrelevant data from consideration, and even so the brain is capable of processing more data in a given time then it normally does.

Have you ever hear the saying about time standing still. Say your in an accident, or you are in perceived danger. You will notice that time seems to slow down. Well its not time that is slowing down it is your brain expanding its processing of data many fold. So you are appreciating every moment more fully. This will give you an appreciation of the filtering that usually takes place. You will also notice a crispness to the world.

The human brain rarely runs at full fidelity. In fact were it to run at full fidelity for a prolonged period of time you would die. The hardware was never intended for strenuous use. Not to mention you would go mad, because all your sense acuity increases as well. You can feel more, hear more, and you ability to detect other radiations increases. Yes humans can and do hear radio waves, Microwaves, and can every detect magnetic irregularities. No bullshit you do have sixth senses.

Microwaves, and radio can be detected through the swelling of ones brain how sick is that.

But science can determine the chemical processes that are involved and they have that fairly well mapped out. Your eye can only see RGB you have a cone for each one and then there are rods. Rods and cones produce seperate chemicals. here is what happens when light hits the eye.

 

1. In the dark, opsin is bound tightly to retinene.

2. When light intensity is increased, retinene changes shape.

(This is a structural change from cis- to trans- form.)

3. Opsin cannot hold onto retinene, retinene comes off (this process is called bleaching).

4. Generator potential is produced when the membrane of a Rod is depolarized.

5. Generator potentials summate (add together) to form an action potential.
6. A nerve impulse is fired off to brain via the Optic Nerve.
7. Rhodopsin is reformed when retinene resumes its original shape using the energy in mitochondria (the power-house of every cell). This is light independent (does not need light).
8. Rhodopsin is ready to be bleached again.

 

It is not that dissimiliar from when a light hits a CCD

 

What dodece is talkign about is not even eyesight he is talking about short term and long term memory. The time it takes for the eye to complete a cycle particularly for the cones is set in stone. However if you flood the hypothalmus with dopamine and adrenaline you enhnace your short term memory. This is why time dialation occurs when some people smoke the weed by the way.

 

You brain swells when exposed to microwaves becuase it mostly water and microwaves excite water cuasing them to spin there spin increases collions with other water molecules and this is known as heat because they colide more often they push each other away and thus expand. Hence how a microwave oven works.

Thanks but errmmmm forgive the typos. I always do that.
