| This article is a transcription of an electronic symposium in which some active researchers were invited by the Brazilian Society for Neuroscience and Behavior (SBNeC) to discuss the last decade's advances in neurobiology of learning and memory. The way different parts of the brain are recruited during the storage of different kinds of memory (e.g., short-term vs long-term memory, declarative vs procedural memory) and even the property of these divisions were discussed. It was pointed out that the brain does not really store memories, but stores traces of information that are later used to create memories, not always expressing a completely veridical picture of the past experienced reality. To perform this process different parts of the brain act as... |

| This paper, by inserting itself in the field of study that has tried to display some thoughts on the pedagogic practices brought by the new educational technologies, aimed at uncovering the meanings attributed by both students and teachers to the use of the technology of information as a mediator in the teaching-learning relation in the undergraduate Business Program of the Universidade Federal de Lavras (UFLA). The analytical effort done here shows that the technology of information as a mediator of this relation gets different meanings both for teachers and students. In the perception of those actors, the technologies of communication and information- when performing the role of mediators in the teaching-learning relation in management- stimulate the... |

| This article is a transcription of an electronic symposium in which active researchers were invited by the Brazilian Society of Neuroscience and Behavior (SBNeC) to discuss the advances of the last decade in the neurobiology of emotion. Four basic questions were debated: 1) What are the most critical issues/questions in the neurobiology of emotion? 2) What do we know for certain about brain processes involved in emotion and what is controversial? 3) What kinds of research are needed to resolve these controversial issues? 4) What is the relationship between learning, memory and emotion? The focus was on the existence of different neural systems for different emotions and the nature of the neural coding for the emotional states. Is emotion the result of the... |

| This article is an edited transcription of a virtual symposium promoted by the Brazilian Society of Neuroscience and Behavior (SBNeC). Although the dynamics of sensory and motor representations have been one of the most studied features of the central nervous system, the actual mechanisms of brain plasticity that underlie the dynamic nature of sensory and motor maps are not entirely unraveled. Our discussion began with the notion that the processing of sensory information depends on many different cortical areas. Some of them are arranged topographically and others have non-topographic (analytical) properties. Besides a sensory component, every cortical area has an efferent output that can be mapped and can influence motor behavior. Although new behaviors... |

| Auctions are common mechanisms for identifying prices and suppliers of commodities and are particularly important in agricultural marketing. Information asymmetries among bidders may be ameliorated over time through some form of learning. In this study, we incorporate prior decisions to participate, information from previous auctions, and firm-specific attributes to explain both the decision to bid and the level of the bid. Our analysis uses data from Egyptian oilseed tenders, an important market both for oilseeds and tendering. Because of the unbalanced nature of the panel data, we are able to evaluate the effects of signals received from previous tenders. We find that firms learn from previous auctions and can gain an informational advantage through... |

| We studied some of the characteristics of the improving effect of the non-specific adenosine receptor antagonist, caffeine, using an animal model of learning and memory. Groups of 12 adult male Wistar rats receiving caffeine (0.3-30 mg/kg, ip, in 0.1 ml/100 g body weight) administered 30 min before training, immediately after training, or 30 min before the test session were tested in the spatial version of the Morris water maze task. Post-training administration of caffeine improved memory retention at the doses of 0.3-10 mg/kg (the rats swam up to 600 cm less to find the platform in the test session, P<=0.05) but not at the dose of 30 mg/kg. Pre-test caffeine administration also caused a small increase in memory retrieval (the escape path of the rats... |

| This study evaluated the possibility of decreasing defecation in a bedding area by inducing a heifer to visit a feeding station within a few minutes or immediately after standing. An experimental paddock (11.3 x 6 .8m) was made outdoors. Half of the paddock was roofed and bedded with straw to form a resting area. A feeding station was situated in the remaining area of the paddock，which was designated as the feeding area. Six Holstein heifers，the test subjects，were grouped together in the paddock. A standing detection device was developed and attached to the heifer's left hind leg. The feeding station had an antenna that identified the heifer carrying the ID-tag when it entered the station. This experiment included control period and an experimental... |

| Milk producers in northern Australia are attempting to make rapid adjustments to production systems that enable them to compete in a newly deregulated market, although there is uncertainty about how to do this. Through industry consultation and expert review a process was developed to identify production systems that may be capable of supporting economic targets of 10% return on assets and 600,000 L milk/labour unit. A broadly based project team in terms of disciplines then used this process to identify five production systems which were each applicable to substantial numbers of current milk producers. These were modelled using whole farm economic analyses and annual feed planning, using an iterative process over an extended period, to determine the... |

| This Brief reports the results of a study that explored the role of human resources policies and practices in fostering knowledge sharing and organizational learning. The study examined six centres of the Consultative Group on International Agricultural Research (CGIAR) and six organizations that are considered to be leaders in the field of knowledge sharing and organizational learning. Five of these were public or non-governmental and the sixth was a private corporation. All the organizations studied (including the CGIAR centres) are promoting knowledge sharing and organizational learning to some extent, generally in the context of broader organizational change. Some have comprehensive, integrated approaches to organizational change, but most efforts tend... |

| Evaluation processes of all types, including monitoring, review and impact assessment, offer unique opportunities for learning and provide useful feedback on what works and what doesn’t, and the reasons for success or failure. Involving staff members, partners and beneficiaries in the evaluation process allows them to reflect on their work, revisit their understanding of the project’s goals and activities, assess their effectiveness and take ownership of the evaluation findings. The knowledge created and the lessons learned through evaluation subsequently provide a basis for better project planning and implementation. This Brief outlines an evaluation approach that promotes learning and program improvement; it contrasts this approach with... |

| Preparing an ‘innovation history’ is a method for recording and reflecting on an innovation process. People who have been involved in the innovation jointly construct a detailed written account (sometimes referred to as a ‘learning history’) based on their recollections and on available documents. The process of preparing this history stimulates discussion, reflection and learning amongst stakeholders. Subsequent planning can build on the lessons learned, formulate a shared vision and act as a catalyst for change. Based on the initial detailed account of the innovation process, more concise informational products can be prepared that summarize the innovation process for wider dissemination of findings. These may include public awareness materials, policy... |
