Schizophr Res
. 2001 May;
50(1-2):55-60.
PMID: 11378314
We explored and refined the hypothesis that during a first episode of acute schizophrenia a disorganization of brain functioning is present. A novel EEG measure was introduced, Global Field Synchronization...

J Psychiatr Res
. 2000 Mar;
34(1):57-73.
PMID: 10696833
Based on an integrative brain model which focuses on memory-driven and EEG state-dependent information processing for the organisation of behaviour, we used the developmental changes of the awake EEG to...

Pascual-Marqui R, Lehmann D, Koenig T, Kochi K, Merlo M, Hell D, et al.
Psychiatry Res
. 1999 Aug;
90(3):169-79.
PMID: 10466736
Functional imaging of brain electrical activity was performed in nine acute, neuroleptic-naive, first-episode, productive patients with schizophrenia and 36 control subjects. Low-resolution electromagnetic tomography (LORETA, three-dimensional images of cortical current...

Eur Arch Psychiatry Clin Neurosci
. 1999 Aug;
249(4):205-11.
PMID: 10449596
Momentary brain electric field configurations are manifestations of momentary global functional states of the brain. Field configurations tend to persist over some time in the sub-second range ("microstates") and concentrate...

Lehmann D, Strik W, Henggeler B, Koenig T, Koukkou M
Int J Psychophysiol
. 1998 Jun;
29(1):1-11.
PMID: 9641243
Prompted reports of recall of spontaneous, conscious experiences were collected in a no-input, no-task, no-response paradigm (30 random prompts to each of 13 healthy volunteers). The mentation reports were classified...

Schizophr Res
. 1998 May;
30(3):221-8.
PMID: 9589516
The aim of this study was to search for differences in the EEG of first-episode, drug-naive patients having a schizophrenic syndrome which presented different time courses in response to antipsychotic...

Koukkou M, Lehmann D, Federspiel A, Merlo M
J Neural Transm Gen Sect
. 1995 Jan;
99(1-3):89-102.
PMID: 8579811
Our approaches to the use of EEG studies for the understanding of the pathogenesis of schizophrenic symptoms are presented. The basic assumptions of a heuristic and multifactorial model of the...

. 1993 Dec;
1(4):203-10.
PMID: 8003918
This paper addresses the issue of mind-brain correspondence, using a novel way to reduce brain electric field data in the frequency domain to estimates of intracerebral model source locations, and...

Biol Psychiatry
. 1993 Mar;

PMID: 8098223
The dimensional complexity of left temporal-parietal and parietal-occipital electroencephalographic (EEG) recordings was assessed by computing the correlation dimension during 20 sec in six recording conditions from 15 first-episode acute schizophrenics...

. 1993 Jan;
5(4):389-94.
PMID: 8357713
A dipole localization method in the frequency domain was used (FFT Dipole Approximation) to assess spatial differences in the spectral EEG reactivity (orienting response) between high and low symptomatic schizophrenics....
