OBJECTIVES In this paper realistic and standard realistic head models were applied to neural source localization. METHODS Three different triangulated head structures; the brain, the skull and the scalp were constructed from MRI information of each patient. For each subject the exact positions of the electrodes were digitized. RESULTS The influence of(More)
SUMMARY The difficuities in assessing the Central Nervous System (CNS) in the course of Systemic Nervous System (SLE) are weli known. A battery of Neurophysioiogicai tests, inciuding EEG and Multimodal Evoked Potenciais was used in order to evaluate CNS disfuntion. Two SLE populations were studied (one with previous neurological symptoms (N = 10) and(More)
Brazil nut, the Bertholletia excelsa seed, is one of the most important non-timber forest products in the Amazon Forest and the livelihoods of thousands of traditional Amazonian families depend on its commercialization. B. excelsa has been frequently cited as an indicator of anthropogenic forests and there is strong evidence that past human management has(More)
Geographic traceability of seafood is key for controlling its quality and safeguarding consumers' interest. The present study assessed if the fatty acid (FA) profile of the adductor muscle (AM) of fresh cockles (Cerastoderma edule) can be used to discriminate the origin of specimens collected in different bivalve capture/production areas legally defined(More)

In this paper we discuss a non-invasive method to localize neural electrical sources using EEG data. In this method, the human head is modelled by a set of four concentric spheres with different conductivities which represent the scalp, the skull, the CSF and the brain or by three triangulated surfaces which approximate the exact head shape (in this model(More)
