Linked to a national emancipation project in the 1950s, the electrification of Guatemala is linked to a genocidal policy against the indigenous populations during the civil conflict of 1960-1996. After the peace agreements of 1996, the electricity industry engaged in a process of liberalisation, tried to distance itself from this past by insisting on the innovative aspect of its projects. However, protests about the quality and cost of the distribution service are emerging. They were structured into a national movement at the turn of the 2010s through the Comité de Desarrollo Campesino. This movement, which was born out of the peace process, became the main mobilising force in the country, campaigning for the renationalisation of electrical energy. Based on an analysis of this article shows how the electricity conflict, as a site of an original association of references, symbols and resources, invites to discuss the analytical frameworks of social movements in Guatemala.

The objective of the present study was to evaluate attentional, motor and electroencephalographic (EEG) parameters during a procedural task when subjects have ingested 6 mg of bromazepam. The sample consisted of 26 healthy subjects, male or female, between 19 and 36 years of age. The control (placebo) and experimental (bromazepam 6 mg) groups were submitted to a typewriting task in a randomized, double-blind design. The findings did not show significant differences in attentional and motor measures between groups. Coherence measures (qEEG) were evaluated between scalp regions, in theta, alpha and beta bands. A first analysis revealed a main effect for condition (Anova 2-way--condition versus blocks). A second Anova 2-way (condition versus scalp regions) showed a main effect for both factors. The coherence measure was not a sensitive tool at demonstrating differences between cortical areas as a function of procedural learning.

Tendon transfer of the tibiliais posterior muscle is a surgical intervention widely employed in orthopedics for the correction of drop foot caused by leprosy. However, few models have proposed a thorough investigation of the brain plasticity phenomenon during tendon transfer. Thus, the present study aimed at analyzing EEG spectral coherence (SC) in patients submitted to tendon transfer of the tibiliais posterior muscle by Srinivasan's technique and quantitative EEG (EEGq). The sample consisted of four subjects with drop foot caused by leprosy. The SC parameter was evaluated in two experimental moments: pre and post-surgery. Results demonstrated a main moment effect for the C3-CZ electrode pair. Specifically, a significant increase in coherence values was observed. However, the ANOVA did not indicate a significant band/moment interaction. It can be assumed that coherence augmentation indicates that functional rehabilitation promoted by this specific surgery yields cortical alterations.
