Previous issue date: 2013-07-30 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Complex network analysis is a powerful tool into research of complex systems like
brain networks. This work aims to describe the topological changes in neural functional
connectivity networks of neocortex and hippocampus during slow-wave sleep (SWS) in
animals submited to a novel experience exposure. Slow-wave sleep is an important sleep
stage where occurs reverberations of electrical activities patterns of wakeness, playing
a fundamental role in memory consolidation. Although its importance there s a lack of
studies that characterize the topological dynamical of functional connectivity networks
during that sleep stage. There s no studies that describe the topological modifications
that novel exposure leads to this networks. We have observed that several topological
properties have been modified after novel exposure and this modification remains for a
long time. Major part of this changes in topological properties by novel exposure are
related to fault tolerance / A an?lise da topologia de redes ? uma poderosa ferramenta no estudo de sistemas
complexos tal como as redes cerebrais. Este trabalho procura descrever as mudan?as na
topologia de redes de conex?o funcional em neur?nios do c?rtex sensorial e do hipocampo
durante o sono de ondas lentas (SWS) em animais expostos ? novidade. O sono de ondas
lentas ? um importante estado do sono onde h? reverbera??o de padr?es de atividade
el?trica ocorridos na vig?lia, tendo com isso papel fundamental na consolida??o de mem?ria.
Apesar de sua import?ncia ainda n?o h? estudos que caracterizam a din?mica da
topologia de redes de conex?o funcional durante este estado. Tampouco h? estudos que
descrevem as modifica??es topol?gicas que a exposi??o ? novidade traz a essas redes.
Observamos que v?rias propriedades topol?gicas s?o modificadas ap?s a exposi??o ? novidade
e que tais modifica??es se mant?m por um longo per?odo de tempo. A maior parte
das propriedades modificadas pela exposi??o ? novidade est? relacionada ? toler?ncia ?
