Prenatal stress can cause long-term effects on cognitive functions in offspring. Hippocampal synaptic plasticity, believed to be the mechanism underlying certain types of learning and memory, and known to be sensitive to behavioral stress, can be changed by prenatal stress. Whether enriched environment treatment (EE) in early postnatal periods can cause a recovery from these deficits is unknown. Experimental animals were Wistar rats. Prenatal stress was evoked by 10 foot shocks (0.8 mA for 1s, 2-3 min apart) in 30 min per day at gestational day 13-19. After weaning at postnatal day 22, experimental offspring were given the enriched environment treatment through all experiments until tested (older than 52 days age). Electrophysiological and Morris water maze testing was performed at 8 weeks of age. The results showed that prenatal stress impaired long-term potentiation (LTP) but facilitated long-term depression (LTD) in the hippocampal CA1 region in the slices. Furthermore, prenatal stress exacerbated the effects of acute stress on hippocampal LTP and LTD, and also impaired spatial learning and memory in the Morris water maze. However, all these deficits induced by prenatal stress were recovered by enriched environment treatment. This work observes a phenomenon that may contribute to the understanding of clinically important interactions among cognitive deficit, prenatal stress and enriched environment treatment. Enriched environment treatment on early postnatal periods may be one potentially important target for therapeutic interventions in preventing the prenatal stress-induced cognitive disorders. 相似文献

作为当代心智哲学九大问题之一的他心问题,肇始于Descartes主义对心身关系的认识。问的是:我们能否知道以及怎么知道他人有心,亦即有思想、经验和情感等?对于他心问题的解决方案,20世纪90年代以来,随着现当代科学技术(尤其是神经生物学、认知神经科学和大脑测试技术等)的深入发展,哲学家与心理学家的知识联姻和交叉合作研究,提供了关于他心问题的若干重要成果和实证资料。他心问题不再成为"理论的死角"。当代社会认知神经科学的出现(social cognitive neuroscience,SCN,2000),在科学方法论上更加关注对社会性心智现象的神经机制考量,一系列研究成果都为揭示他心问题提供了科学旁证。这不仅说明了认识他心的可能性,而且表明了通向认识他心方式的多样性,物理学的方法并不是与他心相隔绝。本文尝试从社会认知神经科学的最新研究进展:镜像神经元系统,他知与自知、他心知觉和再认的社会标记、他心社会判断和归因入手来论证他心问题的可释性,为他心问题的论证提供一条多学科交叉研究的新进路。 相似文献

We adopt a social network perspective to investigate the distinct structural patterns (i.e., centralization and density) of procedural justice (PJ) in teams and the antecedent factors that create them. Across 2 longitudinal field studies in which we gathered social network data from 1,008 workers on 138 teams (Study 1) in China and 672 workers on 125 teams (Study 2) in the United States, we found that differentiation in leader–member exchange relationships significantly influenced the centralization and density of PJ within a team by affecting the level of intrateam trust. Specifically, the more differentiated leader treatment team members received, the lower the level of trust within a team, which resulted in more concentrated (high centralization) and fewer (low density) social interactions among members regarding team PJ. Furthermore, differentiated leader treatment of team members was especially damaging to intrateam trust and, in turn, the structural patterns of team PJ when team members were in close proximity and highly sensitive to equity issues. 相似文献

Patients with traumatic brain injury (TBI) were reported to have difficulty making advantageous decisions, but the underlying deficits of the network of brain areas involved in this process were not directly examined. We report a patient with TBI who demonstrated problematic behavior in situations of risk and complexity after cerebral injury from a traffic accident. The Iowa gambling task (IGT) was used to reveal his deficits in the decision-making process. To examine underlying deficits of the network of brain areas, we examined T1-weighted structural MRI, diffusion tensor imaging (DTI) and Tc-ECD SPECT in this patient. The patient showed abnormality in IGT. DTI-MRI results showed a significant decrease in fractional anisotropy (FA) in the fasciculus between the brain stem and cortical regions via the thalamus. He showed significant decrease in gray matter volumes in the bilateral insular cortex, hypothalamus, and posterior cingulate cortex, possibly reflecting Wallerian degeneration secondary to the fasciculus abnormalities. SPECT showed significant blood flow decrease in the broad cortical areas including the ventromedial prefrontal cortex (VM). Our study showed that the patient had dysfunctional decision-making process. Microstructural abnormality in the fasciculus, likely from the traffic accident, caused reduced afferent feedback to the brain, resulting in less efficient decision-making. Our findings support the somatic-marker hypothesis (SMH), where somatic feedback to the brain influences the decision-making process. 相似文献

Cognitive models of obsessive-compulsive disorder (OCD) assign a central role to maladaptive beliefs. Evaluation of these OCD beliefs in Western countries is commonly accomplished using the Obsessive Beliefs Questionnaire (OBQ) and is important for conceptualizing and treating OCD. It remains unclear if Western models of OCD beliefs are appropriate for sufferers in some non-Western regions, such as China, which represents nearly 20 % of the world population. Thus, the aim of present study is to examine the psychometric properties of a Chinese translation of the OBQ in three samples: 1,322 undergraduates, 139 patients with OCD, and 79 patients with other anxiety disorders. Confirmatory factor analysis revealed poor fit for multiple English-based models of the OBQ. However, an exploratory factor analysis supported an OBQ model that differs slightly from the English version: (1) Perfectionism/Certainty (P/C), (2) Over-Estimation of Threat (T), (3) Importance of Thoughts/Responsibility for Harm (I/R). This Chinese version of the OBQ (C-OBQ) contains 30 items and shows adequate internal consistency, test-retest reliability, construct validity, and criterion-related validity. In China, the C-OBQ may be a useful instrument for delineating cognitive patterns associated with OCD to inform research and treatment. 相似文献
