Low resolution electromagnetic tomography: a new method for localizing electrical activity in the brain.
This paper presents a new method for localizing the electric activity in the brain based on multichannel surface EEG recordings. In contrast to the models presented up to now the new method does notExpand

Reference-free identification of components of checkerboard-evoked multichannel potential fields.
A method is proposed to determine components of evoked scalp potentials, in terms of times of occurrence (latency) and location on the scalp (topography). The scalp field distributions were evoked byExpand

Low resolution brain electromagnetic tomography (LORETA) functional imaging in acute, neuroleptic-naive, first-episode, productive schizophrenia
Functional imaging of brain electrical activity was performed in nine acute, neuroleptic-naive, first-episode, productive patients with schizophrenia and 36 control subjects. Low-resolutionExpand

Functional imaging with low-resolution brain electromagnetic tomography (LORETA): a review.
This paper reviews several recent publications that have successfully used the functional brain imaging method known as LORETA. Emphasis is placed on the electrophysiological and neuroanatomicalExpand

Assessing interactions in the brain with exact low-resolution electromagnetic tomography
Scalp electric potentials (electroencephalogram; EEG) are contingent to the impressed current density unleashed by cortical pyramidal neurons undergoing post-synaptic processes. EEG neuroimagingExpand

EEG alpha map series: brain micro-states by space-oriented adaptive segmentation.
The spontaneous EEG, viewed as a series of momentary scalp field maps, shows stable map configurations (of periodically reversed polarity) for varying durations, and discontinuous changes of theExpand

EEG microstate duration and syntax in acute, medication-naïve, first-episode schizophrenia: a multi-center study
In young, first-episode, productive, medication-naive patients with schizophrenia, EEG microstates (building blocks of mentation) tend to be shortened. Koenig et al. [Koenig, T., Lehmann, D., Merlo,Expand
