Multitasking neurons enhance brain’s computational power

http://web.mit.edu/newsoffice/2013/complex-brain-function-depends-on-flexibility-0519.html

Many neurons, especially in brain regions that perform sophisticated functions such as thinking and planning, react differently to a wide variety of stimulation.

“We started noticing early on that there are a whole bunch of neurons in the prefrontal cortex that can’t be classified in the traditional way of one message per neuron,” said Professor Earl Miller of MIT’s Picower Institute.

Miller and colleagues report that these neurons are essential for complex cognitive tasks, such as learning new behavior.  Professor Stefano Fusi at Columbia University developed a computer model showing that without these neurons, the brain can learn only a handful of behavioral tasks.

    Hey, I think your blog might be having browser
    compatibility issues. When I look at your blog site in Chrome, it looks fine but when opening in Internet Explorer, it
    has some overlapping. I just wanted to give you a quick heads up!
    Other then that, very good blog!

    May I simply say what a relief to find someone who truly knows what they’re discussing on the web.
    You actually realize how to bring a problem to light and make it important.
    A lot more people really need to look at this and understand this side
    of your story. It’s surprising you aren’t more popular given
    that you definitely have the gift.

    At this time it seems like BlogEngine is the preferred blogging platform out there
    right now. (from what I’ve read) Is that what you’re using on your blog?

    When I originally commented I appear to have clicked the -Notify me when
    new comments are added- checkbox and now each time a comment is added
    I receive 4 emails with the exact same comment. There has to be a means you are able to remove me from that service?
    Kudos!
