You can probably imagine our brain. But never before have there been images available at such a high resolution.
People who have put together their own low-tech devices, using inexpensive components including 9-volt batteries, wires and electrodes as a form of DIY neuroscience are sometimes called 'brainhackers' in a similar fashion as 'biohackers', who open up biotechnology. 'Hacking the brain' is both challenging as well as doable, both philosophical as well as practical, both artistic as well as business, both scientific as well as futuristic.
“I think, therefore I am”
As Descartes made us realise: we have the ability to question, to think and to re-think our ideas. This might even be that which makes us human. But how do we question, think and re-think? Scientists have shown that the grey matter inside our heads plays a big role in this all. Artists continue to stimulate our minds, provoke us with new questions and challenge all our ideas. Then again, none of this would have been possible without the continuous technological improvements the developers in this world make possible. But while these disciplines thrive and make new discoveries; what do we really know?
