初级运动区的fMRI实验研究

本实验采用功能磁共振为实验仪器,被试进行运动准备和运动执行两种作业活动,实验设计为延时序列运动任务。在对实验数据进行预处理,反卷积、标准化处理后,采用欧式距离公式进行聚类统计,统计结果显示,M1区不仅具有运动执行和运动准备的功能,还发现其他功能区域的激活,不是单纯的运动执行功能,这一区域与三种活动有关。     

风水理论中的地理思维

风水理论作为我国古人生产生活的依据之一,具有盲目迷信和不科学的地方,但在另一方面,却是古代人民在自然环境中长期形成的生产生活经验的积累,是古代人民伟大智慧的凝结,包含着丰富的地理学思维和合理的科学内核。本文认为:风水理论产生和发展于人类对地理环境的认识;风水理论充分关注地理学中的人地关系议题,体现了古人的地域综合体的思维;风水学从不同尺度来考察人类周围的环境,体现了地理学的尺度观念。

Environmental representations of local communities' spokespersons in protected areas

Despite the popularization of the environmental discourse, rural environmental belief‐systems should not be viewed as homogenous. Focusing on the largest protected area in Greece, we examined heterogeneity in local environmental views. Local spokespersons elicited word associations to two stimulus terms, namely, ‘environmentalists’ and ‘protected area’. Based on association categories for both terms, we identified two sample segments. ‘Naturalists’ appealed to a naturalistic image, which shaped the core compartment of their representations. On the other hand, ‘skeptics’ provided both environmentalist claims and critical accounts. Our findings revealed that the environmental discourse was widely diffused among local spokespersons. Issues of power and participation in decision‐making processes within protected areas are discussed. For instance, dimensions of power and legitimacy were reflected in the frequency of association categories and their allocation among sample segments. Specifically, environmentalist accounts were overtly expressed by both ‘naturalists’ and skeptics, while a more socially, politically and critically inclined view was revealed by a small percentage of associations that were all elicited by ‘skeptics’. We conclude that appreciating the heterogeneity of rural environmental views can reinforce the democratic mandate in environmental policy‐making. Copyright © 2009 John Wiley & Sons, Ltd.     

Effect of unpleasant loud noise on hippocampal activities during picture encoding: an fMRI study

The functional link between the amygdala and hippocampus in humans has not been well documented. We examined the effect of unpleasant loud noise on hippocampal and amygdaloid activities during picture encoding by means of fMRI, and on the correct response in humans. The noise reduced activity in the hippocampus during picture encoding, decreased the correct response and increased the activity of the amygdala. A path diagram using structural equation modeling suggested that hippocampus activity might be depressed by high amygdala activity. Therefore, noise should diminish memory by reducing hippocampal activity, which might be depressed by high amygdala activity.     

小鼠的记忆与脑内突触结构参数变化的相关性

比较不同月龄小鼠学习记忆力与脑内突触结构参数变化的相关性。选用１月龄和６月龄小鼠,用Ｙ－迷宫检测分辨学习能力,用一次性被动回避反应检测记忆力。然后杀鼠取脑,进行超微结构观察和定量分析测定。结果表明：（１）１月龄小鼠的分辨学习能力优于６月龄小鼠,记忆力也有优于６月龄小鼠的趋势。（２）无论在海马或大脑皮层体区,有两种结构参数有一致性增龄变化,即６月龄小鼠突触界面曲率都比１月龄小鼠显著和极显著增大;而６月龄小鼠上述两脑区的突触后致密物质厚度都极显著地小于１月龄小鼠。实验结果提示,脑内突触界面结构的增龄性变化可能是学习记忆力增龄性变化的结构基础。     

Les métamorphoses du système de santé

The normative framework intervened in recent years to renovate and establish a coherent framework to the hospital system questions the bipartite division between private medicine and public medicine. The state supervision, consolidated by the Law of 26 January 2016 on the modernization of the health system, blurs the boundaries and involves renewing the qualification of our health system.     

Position of compression garment around the knee affects healthy adults’ knee joint position sense acuity

Athletes use compression garments (CGs) to improve sport performance, accelerate rehabilitation from knee injuries or to enhance joint position sense (JPS). The position of CGs around the knee may affect knee JPS but the data is inconsistent. The purpose of the present study was to determine the effects of CG position on healthy adults’ knee joint position sense acuity. In a counterbalanced, single-blinded study, 16 healthy young adults (8 female, age: 25.5 y) performed an active knee joint position-matching task with and without (CON) a below-knee (BK), above-knee (AK), or whole-knee (WK) CG in a randomized order on the dominant (CompDom) or the non-dominant leg (CompNon-Dom). We also determined the magnitude of tissue compression by measuring anatomical thigh and calf cross sectional area (CSA) in standing using magnetic resonance imaging (MRI). Subjects had less absolute repositioning error (magnitude of error) in BK compared with CON condition. On the other hand, the analysis of the direction of error (constant error) revealed that in each condition subjects tended to underestimate the target position (AK, BK and CON: 75%; WK: 94%). In WK condition there was a significantly larger negative error (−2.7 ± 3.4) as compared with CON (−1.6 ± 3.7) condition. There also was less variable error, in WK compared to BK and CON conditions, indicating less variability in their position sense using a WK CG, regardless of the underestimation. CG reduced thigh CSA by 4.5 cm² or 3% and calf CSA by Δ1.3 cm² or 1%. The position of CG relative to the knee modifies knee JPS. The findings helps us better understand how the application of a WK CG may support athletic activities.
