[Eeglablist] phase coherence vs phase synchrony

[Ernesto Pereda]

Dear Jaskirat:

There is in fact a website with Matlab scripts for the calculation of 
phase synchrony indexes, namely, Dr. Rosenblum's web site at

http://www.agnld.uni-potsdam.de/~mros/publications.html

As for the different nomenclatures of the phase synchrony indexes and 
further information on the availability of software in this regard, you 
may refer to

Pereda E, Quian Quiroga R, Bhattacharya B (2005)  Nonlinear 
multivariate analysis of neurophysiological signals, Progress in 
Neurobiology 77(1-2):1-37

which you may download in the following link

I apologize for the self-promotion and hope you find the information useful

Yours
