### EEG

Posted:

I am interested in application of cross recurrence plots in EEG brain dynamics data analysis. Suppose we have two data sets: one EEG channel captured with scalp electrodes (in reality we have nine chanels) and one by depth electrodes from thalamus or subthalamic structures (we have 3 times 3 channels for left and right). Can both data sets be described in the same embedding dimension (I have not yet tried this out as my data are not yet in a suitable format). Probably the optimal embedding dimension could be different. How to proceed in such a case in CRP ?

Sincerely,

Dr. G. Otte (georges)

PS I am not a mathematician so please excuse me should this be a silly question. )
