Does the FRN in brain potentials reflect motivational/affective consequence of outcome evaluation?

Electrophysiological studies have utilized event-related brain potentials (ERPs) to investigate neural processes related to the evaluation of the outcome of behavioral performance or to the evaluation of external feedback. The feedback-related negativity (FRN) in brain potentials has been shown to be sensitive to information indicating monetary loss or negative feedback. Since monetary loss usually indicates both the consequence of previous performance and the reward value of stimuli, it is controversial whether the FRN reflects the cognitive process of error detection per se and/or the motivational/affective process related to the subjective evaluation of the error. This study manipulated the motivational/affective significance of negative feedback by penalizing errors in a context-dependent way in a line judgment task. Participants could lose more money in the loss incentive condition or win less money in the win incentive condition if their subsequent judgment of line segments was less accurate, whereas they could receive performance feedback but without monetary incentive in the neutral condition. Results showed that the size of the FRN effect as well as the size of the P300 effect, as assessed by comparing brain responses to the error trials with the responses to the correct trials, increased linearly over the loss, neutral, and win conditions, suggesting that the FRN is sensitive to the motivational/affective evaluation of the performance outcome.

沿空留巷复合底板底臌技术原因与防治对策

复合底板条件下沿空留巷底臌不仅与岩层组成等自然因素有关,还与巷道开挖卸压、工作面超前支护加压、超前支护撤除卸压的反复作用有关。压力的反复作用导致岩体内部裂隙增加,整体发生破坏,进而在巷旁支护高压力作用下底板发生滑移。文中从技术影响与控制的角度出发,提出了＂减少底板反复扰动、弱化巷旁支护传力效果、加强巷旁底板支护＂的防治原则。实测结果表明：在复合底板底臌防治中,将技术原因考虑其中,可以提高防治效果。该研究对同类底板条件下沿空留巷底臌的防治具有一定的借鉴意义。

Morphological evidence for a direct neuroendocrine GABAergic control of the anterior pituitary in teleosts

Summary The anterior pituitary of teleosts is unique among vertebrates in receiving a direct innervation which represents the morphological support of the neuroendocrine control of pars distalis functions. The participation of GABAergic fibers in this innervation was studied by means of immunocytochemistry at the light and electron microscopic levels, using antibodies against GABA. Immunoreactive fibers, characterized by the presence of small clear and dense cored vesicles, were detected in all parts of the gland. Immunopositive terminals were found in close, sometimes synaptic-like, contact with most glandular cell types in the anterior lobe. The data strongly suggest that in teleosts, as in mammals, GABA is involved in the neuroendocrine control of anterior pituitary functions.     

基于CSP的网络协议描述与仿真

首先提出一种基于CSP的协议形式化描述方法.这种方法把协议看成交互实体,从而能很方便地描述协议间的交互关系以及仿真一个协议交互系统.在此基础上,提出了基于CSP的网络协议仿真方法,介绍了仿真流程及其核心模块.这种仿真方法以CSP文档的解析为起始,随后生成协议交互的仿真场景,最终调用仿真核心模块输出仿真结果.给出了TCP协议描述的实例,并以此为输入对TCP协议的连接过程进行了仿真,生成了可视化的仿真结果.这些研究表明这种协议形式化描述及其仿真的方法具有较好的理论和应用价值,并为实现自动化的协议开发平台奠定了基础.
