Use NeuroGuide to Explore Different Normative Montages of A Selected EEG  Sample’s “Theta/Beta” Ratio in Nearly Real-Time.

 

Below is a Linked Ears View of 4.05 Hz where the Z score are greatest in Right Frontal and Right Temporal generally. Use the Key and Arrow Keys to Change the Montage or Double Click with the Left Mouse.

 

 

 

 

 

 

 Below is the Average Reference Normative Z Scores for 3.5 Hz.  A Maximum Z Score of + 2.04 is Present in T6 (Use Tab Key or Double Click on AveRef).

 

 

 

Below are the Laplacian Normative Z Scores for 3.5 Hz.   A More Localized Right Frontal-Temporal Deviation is Present (Use Tab Key or Double Click Left Mouse).

 

 

 

 

 

This is the Linked Ears Reference View of High or Beta  Frequencies, in this case, 19.17 Hz.  Depress the Left Mouse and Slide the Arrow over the Frequencies of Z Scores and Stop When you Find a Maximum Z.

 

 

 

 

 

This is a Laplacian View of 18.62 Hz .  EMG Artifact is clearly localized to T3 and the EMG has little effect on any other channels.
