The midfrontal cortex, and particularly the anterior cingulate gyrus, appears active in many studies of functional imaging.
Various models have competed to explain the functions of the anterior cingulate in relation to its patterns of activation.
We believe that the concept of self-regulation is valuable in considering the role of the cingulate. The sensitivity of the
cingulate to both reward and pain, and evidence for cingulate coupling to cognitive and emotional areas during task performance,
support this identification. Self-regulation is a very broad concept that does not lend itself very well to specific models
or tests, but it does provide a framework for examining development. We trace the role of the midfrontal cortex in evolution
and infant development. Both genes and environment influence self-regulation. The presence of both genetic and environmental
effects raises the issue of their interaction, which we discuss in relation to the dopamine 4 receptor gene and parenting
methods. The role of the midfrontal cortex in self-regulation allows us to consider both brain networks common to all people
and network efficiency underlying individual differences in behavior. This research was supported by NIMH Grant HD5801 to
Georgia State University and by a grant from the Dana Foundation for the study of the arts. 相似文献

This paper is to investigate the use of adaptive observers for the modeling of biological neurons and networks. Assuming that
a neuron can be modeled as a continuous-time nonlinear system, it is possible to determine its unknown parameters using adaptive
observer, based on the concept of adaptive synchronization. The same technique can be extended for the identification of an
entire biological neural network. Some conventional observer designs are studied in this paper and satisfactory results are
obtained, yet with some restrictions. To further extend the applicability of adaptive observers for the modeling process,
a new design is suggested. It is based on a combination of linear feedback control approach and the dynamical minimization
algorithm. The effectiveness of the designed adaptive observer is confirmed with simulations. 相似文献

Three studies were conducted to develop and test a construct of Chinese marital commitment in the context of immigration. ‘Belief in common fate’ refers to an unfailing devotion to a Confucian ideal of the marital union as hierarchical without regard for external contingencies or individual needs. Women who did not believe in common fate reported a more positive affect. When women reported the occurrence of a severe life stressor, a strong belief in common fate was associated with psychological distress and negative affect. We discuss the importance of considering contextual factors, such as migration and life adversity, in interpreting the significance of cultural belief systems. 相似文献

邪教精神依赖和精神痴迷是一种独特的“成瘾”现象,有学者指出精神依赖和精神痴迷者具有精神病样症状,但是治疗这种情况有其独特性,针对邪教精神依赖和精神痴迷者需要进行全面的心理治疗,同时社会支持系统对邪教精神依赖和精神痴迷者起到的作用也非常关键。 相似文献

美德不仅仅是内在心灵品质的存在性特征,而且是以社会健全的人伦价值为前提的.古代伦理学所推崇的美德看似指情感欲望品质的适度,即所谓"中道"或"中庸",但实际上有着当时人伦范型的背景.美德的内在结构有两个方面,即方向和力量.在当代社会中,它以平等自由权利为核心,从而定型为对权利的尊重、公平正义、公共责任、热爱公善等公共美德. 相似文献
