45. The role of the retrosplenial cortex in associative memory

Abstract

Encoding of episodic memories involves associating different features of the environment and experiences. Understanding how sensory-sensory associations are encoded would shed light on the basis of how events are stored in the brain. The retrosplenial cortex (RSC) is known to reciprocally connect to the hippocampal formation and to sensory areas. Its connectivity suggests a role in both episodic and spatial memory processes. A role in the formation and storage of sensory associations might underlie these processes and is supported by RSC-lesion and -inactivation studies. In this thesis, I use optogenetics to inactivate the RSC while mice perform various memory paradigms to clarify the function of this structure in encoding associations to support memory. Thus, I develop a sensory associative memory task in mice which allows me to test sensory-sensory associations. Developing, for the first time, an appetitive sensory preconditioning (SPC) paradigm in mice, failed to provide robust results. So, I chose an aversive SPC paradigm as the best way to probe neutral sensory associations in mice. I show that while control mice successfully learned the preconditioned association in the task, precise closed-loop optogenetic disruption of the RSC when mice form associations between neutral stimuli reduces performance to chance levels. Moreover, I demonstrate that this disruption is independent of spatial confound. Using the same technique to silence RSC activity during short-term or long-term spatial learning did not affect the formation and retrieval of memory, in contrast to previous studies. Finally, in order to truly address the question of how sensory-sensory associations are formed, I present preliminary data of a calcium imaging study aimed at understanding the mechanisms by which these associations are formed in the RSC. In summary, I established a new sensory preconditioning task for mice allowing us to timely probe associative memory between neutral stimuli. Optogenetic silencing of RSC demonstrate the necessity of the RSC in this type of memory and combined with future functional imaging studies will help understand how the brain forms neutral associations.

Abstract

Environmental conditions can change both the quantity and quality of wood formation. This study aimed to evaluate anatomical and chemical changes in the wood of a Eucalyptus urophylla S.T. Blake clone cultivated in four sites of wide climatic conditions in Brazil. Radial samples were used to evaluate xylem anatomy along the growth cycles. Samples with a quarter of a disk were used to perform chemical analyses of extractives, total lignin (LG), syringyl/guaiacyl (S/G), holocellulose, and elemental analysis of wood. The elements Na, K, Ca, Mg, P, Mn, Fe, Zn, Ni, Cu, Cr, Cd, F, and Cl were also quantified. Correlations using the mean values of the variables per site were higher than those using values per tree growth cycle (years). Mean annual air temperature showed the highest correlations with wood density (r = -0.89) and the anatomical characteristics (vessel area: r = - 0.68; fiber wall thickness: r = -0.70; vessel frequency: r = 0.74; and fiber lumen diameter: r = 0.90). Only LG and S/G showed significant correlations with the meteorological variables, with drier sites presenting a higher S/G. The anatomical characteristics change with regionwide climate features, while wood chemical characteristics showed weaker relations with climatic variations. Key words: wood anatomy, wood chemistry, eucalyptus plantations, climate variables, growth rings. Les conditions environnementales peuvent changer la quantite et la qualite de la formation du bois. Par consequent, la presente etude visait a evaluer les changements anatomiques et chimiques du bois du clone de l'Eucalyptus urophylla S.T. Blake cultive dans quatre sites de conditions climatiques variees au Bresil. Des echantillons radiaux ont ete utilises pour evaluer l'anatomie du xyleme tout au long des cycles de croissance. Des echantillons avec le quart d'un disque ont ete utilises pour effectuer les analyses chimiques : matieres extractibles, lignine (LG) total, syringyl/guaiacyl (S/G), holocellulose et analyse elementaire du bois. Les elements Na, K, Ca, Mg, P, Mn, Fe, Zn, Ni, Cu, Cr, Cd, F et Cl ont egalement ete quantifies. Les correlations utilisant les valeurs moyennes des variables par site etaient plus elevees que celles utilisant les valeurs par cycle de croissance de l'arbre (annees). La temperature annuelle moyenne de l'air a presente les correlations les plus elevees avec la densite du bois (r = -0,89) et les caracteristiques anatomiques (zone du vaisseau : r = -0,68, epaisseur de la paroi vegetale : r = - 0,70, frequence du vaisseau : r = 0,74 et diametre de la lumiere des fibres : r = 0,90). Seuls le LG et les S/G ont presente des correlations importantes avec les variables meteorologiques, les sites plus secs presentant des S/G plus eleves. Les caracteristiques anatomiques changent avec les caracteristiques climatiques regionales alors que les caracteristiques des substances chimiques des arbres ont presente des relations plus faibles avec les variations climatiques.

47. Understanding a Brazilian High School Blended Learning Environment from the Perspective of Complex Systems

Author

de Barros, Ana Paula Rodrigues Magalhães, Simmt, Elaine, and Maltempi, Marcus Vinicius

Abstract

The use of technological resources has the potential to make viable new and less traditional methodologies of teaching that take into account student differences. Blended learning can be a way to rethink classes so that students have more freedom in their processes of learning. The goal of this article is to understand a blended learning environment from the perspective of complex systems. We observed the classroom as a complex unit emerging from collective class member interactions. Data from one of two mathematics classes of first year high school students, in São Paulo, Brazil were used in this article. The results suggested that a high school blended learning environment, when seen as a complex system, not only frees students to make personal meaning in their learning processes, but it also provides for collective learning in virtual and face-to-face groups. Features of online discussion groups contributed to the teachers' knowledge about the collective learning, providing them valuable information for formative assessment and pedagogical actions. The blended learning environment seen from a complexity perspective provided evidence that such classrooms demand a different relationship between the teacher, the learner, and the curriculum than relationships observed in the traditional class.
