In this essay we provide an interdisciplinary approach to the problem of the evolution of human cognition and suggest the theoretical framework of genetic system theory (GST) for organizing the relevant content of several disciplines. This bio-social-cultural theory is based on the assumption that organisms are dynamic systems which interact with one another and their environment and are themselves composed of dynamic internal relations at several levels. Special emphasis will be placed upon these internal cellular and molecular mechanisms underlying the physiological mechanisms of learning and memory. The human individual organism is emphasized because in its experiential activity over time it is the site of integration for social, and cultural stimuli and because of its unique properties among living things. The primary disciplines for our discussion are drawn from the biological, social, and humanistic sciences and several concrete examples are given from each science. 相似文献

Estimating the functional interactions and connections between brain regions to corresponding process in cognitive, behavioral and psychiatric domains is a central pursuit for understanding the human connectome. Few studies have examined the effects of dynamic evolution on cognitive processing and brain activation using brain network model in scalp electroencephalography (EEG) data. Aim of this study was to investigate the brain functional connectivity and construct dynamic programing model from EEG data and to evaluate a possible correlation between topological characteristics of the brain connectivity and cognitive evolution processing. Here, functional connectivity between brain regions is defined as the statistical dependence between EEG signals in different brain areas and is typically determined by calculating the relationship between regional time series using wavelet coherence. We present an accelerated dynamic programing algorithm to construct dynamic cognitive model that we found that spatially distributed regions coherence connection difference, the topologic characteristics with which they can transfer information, producing temporary network states. Our findings suggest that brain dynamics give rise to variations in complex network properties over time after variation audio stimulation, dynamic programing model gives the dynamic evolution processing at different time and frequency. In this paper, by applying a new construct approach to understand whole brain network dynamics, firstly, brain network is constructed by wavelet coherence, secondly, different time active brain regions are selected by network topological characteristics and minimum spanning tree. Finally, dynamic evolution model is constructed to understand cognitive process by dynamic programing algorithm, this model is applied to the auditory experiment, results showed that, quantitatively, more correlation was observed after variation audio stimulation, the EEG function connection dynamic evolution model on cognitive processing is feasible with wavelet coherence EEG recording. 相似文献

Studies examining the roles of estrogens and progestins on spatial cognition have been highly contradictory. To determine if the hormonal environment of pregnancy affects spatial cognition, pregnant (n = 7) and virgin (n = 7) Hooded Long-Evans rats were tested in a Morris water maze throughout the 3 weeks of pregnancy and the second week postpartum. Latency to platform, path length, swim velocity, and time in quadrant were compared over trial-days. To compare water maze performance with changes in hormone levels, serum concentrations of estradiol and progesterone were measured on the first, third, and fifth days of testing during the third week of pregnancy. Subjects learned to find the platform as indicated by decreased time and distance to platform over each trial-week and increased time spent in the quadrant where the platform had been located the previous week. However, there were no differences between treatment groups on time or distance to platform over trial-days. Swim velocity did not differ between or within groups over the 4 weeks of testing. Although primigravid and virgin females were similar in their abilities to learn the novel location of a submerged platform and return to it over time, pregnant animals demonstrated less perseveration to previously learned information and were quicker to locate the platform when it moved to a new location. Thus, reproductive status did not affect reference memory but enhanced working memory in the Morris water maze. 相似文献

Background
In addition to its primary role in reproduction estrogen impacts brain areas important for cognition, including the hippocampus and prefrontal cortex. It has been hypothesized that decline in estrogen levels in women following menopause is associated with, or can exacerbate, age-related cognitive decline. However, clinical evidence to support a role for estrogen in preventing cognitive decline in women as they age is equivocal. The critical period hypothesis of estrogen effects on cognition, which proposes that estrogen administration has to be initiated within a critical time period following the loss of ovarian function in order for it to exert positive effects on the central nervous system, is offered as one explanation for inconsistencies across studies.Scope of review
This review details results from basic research using rodent models investigating the effects of estrogen on cognition in the aging female. Emphasis is placed on work investigating effects of timing of initiation of estrogen administration on its subsequent efficacy.Major conclusions
Results of basic research provide support for the critical period hypothesis. Furthermore, results of work in rodent models suggest mechanisms by which the response to estrogen is altered if treatment is initiated following long-term ovarian hormone deprivation.General significance
Understanding if and under what conditions hormone administration following the loss of ovarian function positively affects the brain and behavior could have important implications with regard to female cognitive aging. Results of basic research can contribute to this understanding and provide insight into the complex mechanisms by which estrogen affects cognition. 相似文献17.
Background
Estrogens modulate the morphology and function of the hippocampus. Recent studies have focused on the effects of different types of estrogens on neuroplasticity in the hippocampus and cognition. There are three main forms of estrogens found in mammals: estradiol, estrone, and estriol. The vast majority of studies have used estradiol to investigate the effects of estrogens on the brain.Scope of review
This review focuses on the effects of different estrogens on adult hippocampal neurogenesis, synaptic plasticity in the hippocampus, and cognition in female rats.Major conclusions
Different forms of estrogens modulate neuroplasticity and cognition in complex and intriguing ways. Specifically, estrogens upregulate adult hippocampal neurogenesis (via cell proliferation) and synaptic protein levels in the hippocampus in a time- and dose-dependent manner. Low levels of estradiol facilitate spatial working memory and contextual fear conditioning while high levels of estradiol impair spatial working, spatial reference memory and contextual fear conditioning. In addition, estrone impairs contextual fear conditioning.General significance
Advances in our knowledge of how estrogens exert their effects on the brain may ultimately lead to refinements in targeted therapies for cognitive impairments at all stages of life. However caution should be taken in interpreting current research and in conducting future studies as estrogens likely work differently in males than in females. 相似文献18.

Prior studies of the effects of dehydroepiandrosterone (DHEA) on cognition have produced complex and inconsistent results. We hypothesize that these results may arise, in part, because of DHEA's metabolism into estrogens and androgens that produce opposing effects on cognition. Our study administered 50 mg of oral DHEA daily for 4 weeks in a placebo-controlled crossover design to six postmenopausal women. We measured blood levels of androgens (total testosterone, free testosterone, DHEA, DHEAS), estrogens (estradiol, estrone), and cognitive performance on recognition memory, perceptual identification, digit span memory, and visual attentional vigilance under both drug and placebo conditions. Multiple regression models incorporating the factors of age and body mass index (BMI) were used to ascertain the relation between sex steroids and cognitive performance. Our results demonstrated that estrogens produced a positive effect on recognition memory, while androgens produced a negative effect. This pattern reversed in perceptual identification with estrogens producing a negative effect and androgens producing a positive effect. In addition, BMI produced a negative effect on digit span memory, age produced a negative effect on perceptual identification, and androgens produced a negative effect on visual attentional vigilance. These results help, in part, to explain DHEA's complex effects on cognition. The diverse effects of sex steroids across tasks underscore the importance of identifying the specific cognitive mechanisms influenced by sex steroids and emphasizes that one should not expect sex steroids to produce homogeneous effects across cognitive tasks. 相似文献
