Title: How can brain activity reflecting language function be measured?
Post by: cris6660 on 24/12/2008 15:53:42

Cris asked the Naked Scientists:

Hello Chris!

Is there any way to measure brain waves whilst a person is talking on a cell phone?  I initially thought about using an MRI scan, but I figured the cell phone radiation would interfere with the frequencies used by the machine.  

Any ideas?
Thanks
Cris


What do you think?

Brainwaves are measured using electrodes attached to the scalp : an electroencephalogram (http://en.wikipedia.org/wiki/Electroencephalography).

The activity of different areas of the brain can also be measured using a functional MRI (http://en.wikipedia.org/wiki/Functional_magnetic_resonance_imaging).
