What’s going on in your brain?

Always wondered how your brain exactly works? We might get a clearer idea, as technology progresses we can see the function of the brain by images.

The beautiful image above shows a reflection of connectivity in the brain taken by nuada medial specialist imaging and one of the 2011 Wellcome images award winning photographs.

To give a little introduction in ‘brain imaging’, we can see the anatomy of the brain by MRIs (magnetic resonance imaging) since the 70ies (http://en.wikipedia.org/wiki/Magnetic_resonance_imaging).

Since about 10 years, apart from anatomy, we can also see how chemicals and electrical signals are transmitted in the brain.

The medical database ‘Pubmed’ comes up with about a 1000 hits in the past 10 years (http://www.ncbi.nlm.nih.gov/pubmed?term=Diffusion%20tensor%20tractography%20).

Hopefully this technology will quickly move out of research settings into practice 🙂

    Hi 🙂

    Nice use of links but I think it’s a good idea to take the opportunity to tell your readers a little more about each aspect that you want to cover (and then use the links to provide more background info).

    As a reader I’m curious about what this means to me as an owner of a brain 🙂 Will doctors one day be able to use this to tell me if my ‘connections’ are working OK? Or are there potentially controversial issues, eg people claiming they can use brain imaging to ‘read thoughts’ perhaps as a lie detector.

    Whichever aspect(s) you consider I think it’s helpful to lead the reader through an idea, and put it in context. If I click on a PubMed link for diffusion tensor tractography I’ll arrive on a page full of things I don’t really understand. Maybe a little more “hand-holding” for your reader here?
    But I’m glad that you’re linking to primary research 🙂

    Best wishes,

    I also think it’s good that you provide useful links on your blog; however, to make the post look a bit neater, I would not copy the whole link into it, but “hide” it behind a word instead. That’s very easy to do: When editing your post, write a sentence like “A nice blog on this topic can be found here”, then highlight “here” and click on the little link icon (a chain) – that will open a window into which you can copy your link. Save, publish, and when people then click on “here”, your link will open!
    I personally find that nicer than looking at a long row of useless letters and numbers… 🙂
