Abstract

The spatial power distribution has been studied in magnetoencephalography (MEG) data collected in a subject performing two different yoga breathing exercises specific for the treatment of obsessive compulsive disorder. First of all, in relation with all the frequency components, a characteristic spatial structure of power distribution has been reconstructed using the correlation function for both the recordings. Moreover through the power spectral analysis characterization of the gamma-band activity has been carried on allowing one to underline the differences due to the activities of different phases of the same protocol and the effects of performing different breathing exercises.
