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
