Brief Summary
The objective of the suggested study is to identify changes in MEG correlates caused by the add-on treatment with the changes in negative symptoms of schizophrenia by comparing the change in the MEG correlates of the subjects before and during usage of new add on treatments for negative symptoms. The investigators hypothesize that the gravity of negative symptoms will correlate with a trend towards more aberrant electroencephalographic correlates mainly in continuous parameters, with an emphasis on alpha and delta bands
