Última The influence of bromazepam on cortical power distribution Anais da ABC (AABC) Sampaio,Isabel; Puga,Fernanda; Veiga,Heloisa; Cagy,Mauricio; Piedade,Roberto; Ribeiro,Pedro. The EEG has been widely employed in the assessment of electrophysiological changes induced by distinct medications. Its sensibility in detecting alterations produced by a specific substance may be enhanced by methods of quantitative analyses (qEEG). The present study aimed at investigating the modulatory effects of bromazepam on brain dynamics. The effects of bromazepam (3mg) on EEG power distribution were tested in 10 healthy individuals, in a double-blind experiment. The electrophysiological measure was analyzed across experimental conditions, moments, and electrodes, in the delta, theta, alpha and beta frequency bands separately. A significant decrease of relative power was observed in delta and theta (main effect of condition). No interactions were...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37652008000200012 From autopoiesis to neurophenomenology: Francisco Varela's exploration of the biophysics of being Biol. Res. RUDRAUF,DAVID; LUTZ,ANTOINE; COSMELLI,DIEGO; LACHAUX,JEAN-PHILIPPE; LE VAN QUYEN,MICHEL. This paper reviews in detail Francisco Varela's work on subjectivity and consciousness in the biological sciences. His original approach to this "hard problem" presents a subjectivity that is radically intertwined with its biological and physical roots. It must be understood within the framework of his theory of a concrete, embodied dynamics, grounded in his general theory of autonomous systems. Through concepts and paradigms such as biological autonomy, embodiment and neurophenomenology, the article explores the multiple levels of circular causality assumed by Varela to play a fundamental role in the emergence of human experience. The concept of biological autonomy provides the necessary and sufficient conditions for characterizing biological life and...
