Brain electrical activity (quantitative EEG and bit-mapping neurocognitive CNV components), psychometrics and clinical findings in presenile subjects with initial mild cognitive decline or probable Alzheimer-type dementia.

Clinical, neuropsychological and neuropsychophysiological data (Q-EEG, ERPs and CNV/RT activity) were obtained from 24 patients who had more or less severe presenile primary cognitive decline without depression, and compared with similar data from 10 age-matched healthy volunteers (mean age, 59.4 years). All of the patients (15 M and 9 F; mean age 59.

Cognitive potentials: ipsilateral corticocortical interconnections in prefrontal human cortex ablations.

The research deals with the possible role of the essentially monosynaptic bidirectional corticocortical connections between occipito-temporo-parietal association cortical areas and frontal areas in the genesis of some contingent negative variation (CNV) components, especially on the supramodal dorsolateral prefrontal regions. With standard and topographic mapping methods of analysis, the multicomponent CNV complex formation was examined in 7 patients with extensive frontal cortex ablations exactly identified through CT/MRI examinations, and in 10 normal subjects. On the scalp over the ablated frontocortical areas, no consistent post-warning auditory N100 a-b-c, P200, P300, early and late CNV components were recordable.

Format, organization, and processing of registration dossiers in the European Economic Community (EEC).

The free circulation of drugs among the European Economic Community (EEC) member states ensues from the principles stated by the Treaty of Rome. This is possible thanks to a series of legal and technical directives stating the criteria with which the national authorities--who are sovereign in this matter--must comply. These directives are briefly explained.

[Identification of 46 yeasts from a clinical source: morphological criteria, biochemical and immunological tests].

From clinical specimens (urine, pharyngeal and vaginal exudates, sputum and skin) 46 yeasts have been identified. The cultures have been divided into 3 groups, according to their morphological characters: unicellular, yeasts having hyphae, pseudohyphae, blastospores and yeasts producing also arthrospores. Tests for fermentation and assimilation of carbohydrates have been employed for S.
