Hi all. I have been researching eeg sensors for a school psychology project. I understand this technology is still in its infancy where individual sensory data accuracy varies from subject to subject. My question is, how are hospitals and scientists able to measure brain activity with better accuracy?
Probably by using more expensive sensors. But in most cases accuracy is not the goal because the values are always interpreted relatively, you don't compare the values from one subject to the other, just compare the different values you get from the same subject.
