* The limits of conventional technology such as EEG and MRI

** EEG and MRI are not very exact; they are more of an overall measure of the activity of the brain.

** MRI can only detect what areas of the brain are activated and at what level they are being activated too.

** EEG can only detect the electromagnetic field that is being generated by the brain. What is happening in the brain is then inferred from this. It does not get down to the basics of the brain.

* New research and technologies that can address this

** Work is being done to determine the exact neural circuits that are activated when the brain is working.This is done by altering the genetic code of the neurons to be activated when a blue light is shone onto it. This hows promise on the path to understanding the brain fully because it would allow us to create complex bci’s that understand the nature of the neural circuits of the brain and would work deeply with the neural circuits of the brain. Also, work is being done on creating neurons that react to orange light as well, effectively making blue on and orange off. This would allow us to extract a binary code from the brain i.e. the software that it runs on.
