fMRI Data Reveals the Number of Parallel Processes Running in the Brain

Submitted by: Hologram @ 03:15 AM | Sunday, November 9, 2014 | (url: http://www.techno...)

The human brain carries out many tasks at the same time, but how many? Now fMRI data has revealed just how parallel gray matter is. ... Although the analysis is complex, the outcome is simple to state. Georgiou says independent component analysis reveals that about 50 independent processes are at work in human brains performing the complex visuo-motor tasks of indicating the presence of green and red boxes. However, the brain uses fewer processes when carrying out simple tasks, like visual recognition.

That's a fascinating result that has important implications for the way computer scientists should design chips intended to mimic human performance. It implies that parallelism in the brain does not occur on the level of individual neurons but on a much higher structural and functional level, and that there are about 50 of these. 'This means that, in theory, an artificial equivalent of a brain-like cognitive structure may not require a massively parallel architecture at the level of single neurons, but rather a properly designed set of limited processes that run in parallel on a much lower scale,' he concludes.

50.

The front page wouldn't let me put the whole article in, it was over the 2000 character limit.
Here's a link to the full paper: arxiv.org/abs/1410.7100 Click PDF on the right.

50-60. It's at the conclusion at the bottom. Says most of the processes happen when doing motor skills, less when doing visual stuff (looking at porn).

So what they need to do is build a robot with 50-60 cores. And if you think about it, seems logical. Deep Blue (Chess Computer from IBM) had a ton of processors, so does Watson (Jeopardy Computer from IBM).

I read it and decided the conclusion they came to was basically a guess because they didn't really have any idea how to interpret their results.

Here's a thought.

Human brains aren't computers.

In other shocking news, humans move without the use of gears and springs.

The results make for interesting reading. Although the analysis is complex, the outcome is simple to state.

Holy shit! What a revelation!

Hologram -rep for -rep. I don't see you trying to make a good post.

exactly. lol @ trying to compare CPU cores the the human brain. does my computer have an internal dialogue?

Very good!

yes, I came to an obvious conclusion. don't fucking patronize me.

brb upgrading the graphics card in my head

ur gonna have a cpu bottle neck w/ ur nigger brain

50-60 processes at once seems lower than I would have thought. I wonder how much that amount would vary while under the influence of different drugs, like speed or heroin.
