The perirhinal and entorhinal cortices are critical components of the medial temporal lobe (MTL) declarative memory system. Study of their specific functions using blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI), however, has suffered from severe magnetic susceptibility signal dropout resulting in poor temporal signal-to-noise (tSNR) and thus weak BOLD signal detectability. We have demonstrated that higher spatial resolution in the z-plane leads to improved BOLD fMRI signal quality in the anterior medial temporal lobes when using a 16-element surface coil array at 3 T (Tesla). Using this technique, the present study investigated the roles of the anterior medial temporal lobe, particularly the entorhinal and perirhinal cortices, in both object and spatial memory. Participants viewed a series of fractal images and were instructed to encode either the object's identity or location. Object and spatial recognition memory were tested after 18-sec delays. Both the perirhinal and entorhinal cortices were active during the object and spatial encoding tasks. In both regions, object encoding was biased to the left hemisphere, whereas spatial encoding was biased to the right. A similar hemispheric bias was evident for recognition memory. Recent animal studies suggest functional dissociations among regions of the entorhinal cortex for spatial vs. object processing. Our findings suggest that this process-specific distinction may be expressed in the human brain as a hemispheric division of labor. 相似文献

Twin and adoption studies have demonstrated a significant contribution of both genetic and environmental factors to antisocial and delinquent behavior. Associations have been reported between the serotonin transporter (5‐HTT) and aggression, and between socioeconomic status (SES), aggression, and serotonergic functions of the brain. We aimed to investigate associations between the 5‐HTTLPR genotype and family SES in relation to delinquent behavior among adolescents. A total of 1,467 17‐ to 18‐year‐old students in the county of Västmanland, Sweden, anonymously completed a questionnaire and gave a saliva sample. Family SES had a U‐shaped relation to delinquency, where adolescents with low and high family SES were the most delinquent. There were curvilinear interactions between the 5‐HTTLPR genotype and family SES in relation to delinquency. Among individuals having high family SES, boys with the LL (homozygous for the long allele) or LS (heterozygous) genotypes and girls with the SS (homozygous for the short allele) or LS (heterozygous) genotypes showed the highest delinquency scores. Among individuals having low family SES, boys with the LL (homozygous for the long allele) genotype and girls with the LS (heterozygous) genotype showed the highest delinquency scores. The present study suggests evidence for an interaction between family SES and the 5‐HTTLPR genotype in relation to juvenile delinquency. Aggr.

In this paper the objectives of a new international research project that focuses on the perception of leadership across cultures will be presented. The definition of leadership will be discussed in relation to cross-cultural leadership research. The ideas and theory on which the project is based will be introduced along with several of the hypotheses the project is designed to test. Besides testing the general hypotheses, results obtained in the GLOBE study can also be used for a more focused comparison between two countries. In this paper, differences in preferred leadership attributes and national culture dimensions in The Netherlands and Poland are presented. A total of 287 Dutch managers from six organizations and 277 Polish managers from six organizations filled out questionnaires. The results indicate that Dutch and Polish cultures differ strongly on power distance, uncertainty avoidance and future orientation. Regarding preferred attributes for outstanding leadership, Polish respondents score especially high on administrative skills, vision, and diplomacy, whereas Dutch managers emphasize integrity, inspirational behavior and vision. Polish respondents are also less negative about autocratic leadership. 相似文献
