Recording your brainwaves

Soon you will be able to walk around and do your daily routines while your brainwaves are being recorded.

It is more than 90 years since the electroencephalogram (EEG) machines started recording human brainwaves. But even now the EEG machines you see in hospitals are formidable devices that attaches metallic electrodes to the skin of your head. You can tolerate it for some minutes. But to continuously record the brainwaves over weeks? Even when you are mobile and active?

Now here is the first step: soft and cuddly electrodes that you can wear around your head for weeks without any discomfort. Scientists from 14 different organisations had to collaborate to make the proof of concept – something that can be molded to attach itself to even a complex surface like the ear.

The immediate use of this innovation will for epileptics to provide prior warning of onset of fits, for doctors to come to quick differential diagnosis in neurological disorders and for scientists studying human cognition.. 

But it is still one step away from the dream that I have: feed the signals to a deep brain magnetic stimulator attached to another person and through error feedback and correction, achieve telepathy.  

Or is it one step away from my nightmare: mind reading and mind control?
