if so, upload your brain pics to http://brainmeta.com/uploader/ and post them in the forum. I put the results of a recent scan as my avatar pic, and also posted it below. It was rendered using the freeware program, MRIcro, which reads in Analyze formatted anatomical MRI data.

If you haven't been scanned, find out about becoming a subject for an MRI experiment and request to have a copy of your anatomical MRI scan. Then you can use MRIcro to produce 3D renderings of your brain and post it here for everyone to see.

That is SWEET dude!

I like the colour and the amplification of! I think it might benifit from a different background though (the white seems too intense).

I've used and am using that tonal range and frequency in my paintings.

thanks Trip.

Very nice indeed.

thanks Life. Get scanned if you can. If you're at a university, it should be fairly easy.


Here's the view from above:

26 human brains available at http://brainmaps.org/index.php?action=view.../h.sapiens/MRI/

hey I noticed a diffrence in the size of the brains, can you tell me the major effects that brain size has on a person? and their is definatly a diffrence in overall brain shape as well, does this have any significance?

I do assume that the larger the brain the more intelligent one is but I am wondering about a more specific set of details, like does a inch of brain size hold much significance or is it a minute diffrence in intelligence ect?

The correlation between brain size and intelligence is somewhat controversal; nonetheless, there are studies showing such a correlation. Of course, correlation does not imply causality. Other interesting things to look at are cortical thickness, which can be done in MRI, and synaptic densities, which cannot.

I had originally posted the rendered brains at the above url at nonuninform scales, with the result that some 'big brains' appeared smaller than they should have been. I have corrected the issue. Now all of the brains are correctly scaled.

Note that, with all of the brains (except one), the perspective is that you are looking down on the brain from above, and that the front of the brain is pointing towards the top of the page. The sole exception (thus far) is the fourth brain, which is a frontal view.

oh okay, so the idea is that the brain size may not nessecarily denote intelligence just like the size of a object does not denote its weight. So thus a person might have a massive brain but it could be equivilant to wood with a low density, where as a smaller brain could have a higher density like a rock.. hmm all very intresting thanks for the info shawn

maximus, healthy brains of the same species don't have significantly different densities.

.. it is metaphorical cerebral, it is about measuring the densities of cortical thickness and synaptic densities..

I know you didn't mean it literally. I fixed my response. But you make a point. If there are different cortical thicknesses and synaptic densities, then some global measure of the brain, like density (where I presumed you meant weight per volume), should pick this up. However, i don't think the differencein density is significant enough to be measured. Differences in synaptic densities are another matter; they can be measured and compared.

Id rather see one that tells me something about you, like some sort of color coded one that shows where your activity is the most or something. my brain would probably look like a disaster

yeah, I'd like to see that too, a sort of functional map. I have done a little work on visualizing functional connectivity in the human brain using color maps but only applied the method to a couple of brains. With more data and more time, something interesting could come out of it. A lot of people are a little concerned when they first get scanned, of finding out something is wrong with their brain. But it's very unlikely. There's a lot of natural variability between human brains but rarely do you see something really strange.
