The role of the hippocampus and post-learning hippocampal activity in long-term consolidation of context memoryGulbrandsen-MacDonald, Tine L, University of Lethbridge. Faculty of Arts and Science January 2011 (has links)
Sutherland, Sparks and Lehmann (2010) proposed a new theory of memory consolidation, termed Distributed Reinstatement Theory (DRT), where the hippocampus (HPC) is needed for initial encoding but some types of memories are established in non-HPC systems through post-learning HPC activity. An evaluation of the current methodology of temporary inactivation was conducted experimentally. By permanently implanting two bilateral guide cannulae in the HPC and infusing ropivacaine cellular activity could be reduced by 97%. Rats were trained in a context-fear paradigm. Six learning episodes distributed across three days made the memory resistant to HPC inactivation while three episodes did not. Blocking post-learning HPC activity following three of six training sessions failed to reduce the rat’s memory of the fearful context. These results fail to support DRT and indicate that one or more memory systems outside the HPC can acquire context memory without HPC post-event activity. / x, 85 leaves : ill. ; 29 cm

Gegen(-) AbwesenheitenBolte, Rike 18 February 2014 (has links)
Während der letzten argentinischen Diktatur (1976-1983) wurden zehntausende Menschen in geheimen Lagern festgehalten, gefoltert und ermordet – dann ''verschwanden'' sie. Die meisten Fälle sind nur schwer rekonstruierbar, viele Täter kamen ungestraft davon. Für diese staatsterroristische Praxis wurde die Bezeichnung erzwungenes Verschwinden eingeführt (spanisch desaparición forzada). Die Untersuchung beschäftigt sich mit medialen und ästhetischen Verfahrensweisen, die in Argentinien in der Auseinandersetzung mit der desaparición forzada entwickelt wurden. Im Vordergrund steht die These, dass die gewaltsame Depräsentation der Opfer zu einem gesellschaftlichen ''Wahrnehmungsmord'' ("percepticidio") geführt hat. Die medialen Strategien und ästhetischen Produktionen, die die Untersuchung analysiert, markieren den gegenwärtigen Stand einer transgenerationellen kulturellen Bearbeitung dieser wahrnehmungsrelevanten sozialen und politischen Erfahrung. Es handelt sich um Produktionen im Bereich Narrativik, Lyrik, Fotografie, Film und Theater, die im Kontext der Memoria-Hochkonjunktur nach 1989 und der digitalen Globalisierung stehen. Félix Bruzzone, Mariana Enríquez und Martín Gambarotta, Virginia Giannoni und Lucila Quieto sowie Albertina Carri und Lola Arias haben Kontra(re)präsentationen zum gewaltsamen Verschwinden entworfen, die materiell, meta-medial und kontrainformativ verfahren. Nach diskursanalytischen, repräsentations- und medientheoretischen Einführungen sowie einer Reihe terminologischer Definitionen arbeitet die Untersuchung an diesen Produktionen einer postdiktatorischen Generation, die als "Camada Cadáver" bezeichnet wird, heraus, dass ein ''Phänomen'' wie das erzwungene Verschwinden – das in vielfache Referenzlosigkeit führt – ästhetische Strategien motiviert hat, die als beispielhaft emergent und experimentell einzustufen sind, weil sie neue Erkenntnisse für die noch unabgeschlossene Erforschung eines der vielen Terrorregimes des 20. Jahrhundert liefern. / During the Argentinean dictatorship (1976-1983), tens of thousands of people were kept in secret camps, were tortured, murdered, and ''disappeared''. Most cases are difficult to reconstruct. Many of the offenders have remained unpunished. The term "forced disappearance" (Spanish desaparición forzada) was introduced for this act of state terrorism. This study addresses medial and esthetic processes that were developed in light of the debate on desaparición forzada in Argentina. At the heart of the study is the hypothesis that the violent ''depresentation'' of the victims has led to ''cognitive murder'' ("percepticidio"). The media strategy and esthetic productions analyzed in the study represent the current state of the art of the trans-generational cultural work on cognition relevant social and political experiences. The productions in the field of the study of narration, poetry, photography, film, and theater have emerged in context of the post 1989 memory-boom and digital globalization. Félix Bruzzone, Mariana Enríquez und Martín Gambarotta, Virginia Giannoni, and Lucila Quieto as well as Albertina Carri and Lola Arias have conceptualized counter(re)presentations to violent disappearance which proceed materially, meta-medially, and counter-informatively. Following introductions on discourse analysis, representation theory, and media theory as well as a number of terminology definitions, the study analyzes the above mentioned productions created by a post dictatorship generation, which are being referred to as the "Camada Cadáver", and shows that the ''phenomenon'' of forced disappearance, which leads to a repeated lack of reference, has motivated esthetic strategies that are to be classified as exemplarily emergent and experimental, because they have produced new insights for the unfinished research on one of the many terror regimes of the twentieth century.
