Standardized low-resolution brain electromagnetic tomography (sLORETA): technical details.
Scalp electric potentials (electroencephalograms) and extracranial magnetic fields (magnetoencephalograms) are due to the primary (impressed) current density distribution that arises from neuronal postsynaptic processes. A solution to the inverse problem--the computation of images of electric neuronal activity based on extracranial measurements--would provide important information on the time-c...
متن کاملFunctional 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 neuroanatomical basis of the method, on the localization properties of the method, and on the validation of the method in real experimental human data. Papers that criticize LORETA are briefly discussed. LORETA publica...
متن کاملObsessive-compulsive dimension localized using low-resolution brain electromagnetic tomography (LORETA).
Electroencephalographic mapping techniques have been used to show differences between normal subjects and those diagnosed with various mental disorders. To date, there is no other research using the techniques of low-resolution brain electromagnetic tomography (LORETA) with the obsessive-compulsive disorder (OCD) population. The current investigation compares current source density measures of ...
متن کاملStandardized low-resolution electromagnetic tomography in obsessive-compulsive disorder--a replication study.
Previous EEG source localization studies in obsessive-compulsive disorder (OCD) reported ambiguous results. The reason probably lies in different OCD samples included in the studies - obsessive-compulsive subjects selected based on a psychopathology questionnaire (the Symptom Checklist - Revised), drug-naïve OCD cases or patients with a long-term disorder. This study was conceived as a replicat...
متن کاملAssessing 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 neuroimaging consists of estimating the cortical current density from scalp recordings. We report a solution to this inverse problem that attains exact localization: exact low-resolution brain electromagnetic tomogr...
