Under the eaves of the house. About the experience of historical reconstruction of the Movimiento Campesino de Santiago del Estero – Vía Campesina

Esta crónica narra y analiza la experiencia de reconstrucción histórica del Movimiento Campesino de Santiago del Estero – Vía Campesina. Posee la singularidad de haber sido elaborada por algunos de los y las protagonistas de dicho proceso. En la misma, es posible hallar reflexiones acerca de la tensión entre las nociones de memoria e historia, partiendo siempre de las voces y los relatos de los propios campesinos y campesinas. Debate también aspectos centrales de las tensiones que subyacen al rol de los/as investigadores/as en la reconstrucción de la memoria de los movimientos sociales.This chronicle narrates and analyzes the experience of historical reconstruction of the Movimiento Campesino de Santiago del Estero – Vía Campesina. It presents the singularity of having been elaborated by some of its own protagonists. It includes considerations about the tension between the notions of memory and history, taking always as a start point the voices and narrations of the peasants. It also debates central aspects related to the tensions that underlie the role of researchers in the reconstruction of the memories of social movements.Instituto de Física de Líquidos y Sistemas Biológico

Private Narratives and Infant Views: Iconizing 1970s Militancy in Contemporary Argentine Cinema

This is the author's accepted manuscript, made available with the permission of the publisher.This article analyses the connections between the subjective turn in the representation of militancy, iconicity, and historical examination in Infancia clandestina, a recent Argentine film that portrays the 1970s armed struggle through a child’s lens. Breaking with the leading interpretation that praises the movie because of its original exposition of left-leaning violence, I contend that this coming-of-age story fits within a version of militancy that originated in the mid-1990s and that has become quite common since the advent of the Kirchner administration in 2003. This particular version relies on a privatized and archaic image of activism that is at the core of the global iconization of 1970s militancy. An analysis of the filmic use of an infant perspective and of anime-style cartoons illuminates how contemporary Argentine cinema both registers and participates in this iconizing process

Cocaine supersensitivity and enhanced motivation for reward in mice lacking dopamine D2 autoreceptors

Dopamine (DA) D2 receptors expressed in DA neurons (D 2 autoreceptors) exert a negative feedback regulation that reduces DA neuron firing, DA synthesis and DA release. As D2 receptors are mostly expressed in postsynaptic neurons, pharmacological and genetic approaches have been unable to definitively address the in vivo contribution of D 2 autoreceptors to DA-mediated behaviors. We found that midbrain DA neurons from mice deficient in D2 autoreceptors (Drd2 loxP/loxP; Dat+/IREScre, referred to as autoDrd2KO mice) lacked DA-mediated somatodendritic synaptic responses and inhibition of DA release. AutoDrd2KO mice displayed elevated DA synthesis and release, hyperlocomotion and supersensitivity to the psychomotor effects of cocaine. The mice also exhibited increased place preference for cocaine and enhanced motivation for food reward. Our results highlight the importance of D 2 autoreceptors in the regulation of DA neurotransmission and demonstrate that D2 autoreceptors are important for normal motor function, food-seeking behavior, and sensitivity to the locomotor and rewarding properties of cocaine.Fil: Bello Gay, Estefania Pilar.
