[Our experience with quantitative analysis of EEG reactivity I. Spectral analysis ]

JÁRDÁNHÁZY Tamás, ŐRI Zsolt

[Our studies show that the synchronization and desynchronization of EEG background activity changes in response to barbiturate anesthesia can be distinguished from each other by our spectral analysis procedure. We found that the synchronization response is characterized by a larger magnitude increase in power in the theta, alpha and beta bands, and desynchronization by a larger magnitude decrease in power in the theta and alpha bands. Our results are consistent with previous visual observation,... tovább »

[Our experience with quantitative analysis of EEG reactivity II. Period and amplitude analysis]

JÁRDÁNHÁZY Tamás, ŐRI Zsolt

[Our studies show that period and amplitude analysis can be used to distinguish between the two types of background activity changes induced by stimulation - synchronization and desynchronization - but this procedure does not provide as accurate an insight into the details of what is happening as spectral analysis of the same material. Also with this method, the changes in the theta and alpha bands were found to be the most useful for separating the two types of reactions; the synchronisation... tovább »

[Our experience with quantitative analysis of EEG reactivity III. Hjorth parameter analysis ]

JÁRDÁNHÁZY Tamás, ŐRI Zsolt

[Our results suggest that our Hjorth parameters, estimated by the simplified method of Saltzberg and Burch, and the derivatives describing their changes over time, can be used to characterize and detect changes in synchronization and desynchronization background activity in humans induced by stimulation. The results obtained in response pattern recognition approached those obtained in our studies with spectral analysis and were superior to those obtained with period and amplitude analysis.

[Reasons for lack of cooperation with medication in schizophrenic patients ]

BARTKÓ György, BÉKÉSY Mariann, SZÉLL Katalin, ZSOMBÓK Terézia, MAYLÁTH Eszter

[The authors examined the relationship between subjective response to neuroleptic treatment and compliance in 51 schizophrenic patients. 47% of the patients subjectively perceived the treatment as unpleasant and 79% of them belonged to the group of treatment non-compliant. No association was found between subjective response and current side effects. It was confirmed that among the psychopathological symptoms observed at discharge, delusions of grandiosity and lack of illness awareness were... tovább »
