In recent years, research has progressively increased the importance of considering sex differences in stress and fear memory studies. Many studies have traditionally focused on male subjects, potentially overlooking critical differences with females. Em
In this line, the Tachykinin 2 (Tac2) pathway in the central amygdala (CeA) has been shown to be sufficient and necessary for the modulation of fear memory consolidation. CeA-Tac2 antagonism and its pharmacogenetic temporal inhibition impair fear memory in male mice. Surprisingly, we demonstrate ...
Despite the wealth of literature regarding STEM anxiety, little work has characterized the large-scale brain networks that may be linked with this barrier to learning and achievement in STEM students. However, significant prior neuroimaging research has contributed to our understanding of the neurobiologi...
In addition, whenever possible, family members of the twins were also assessed: 1,690 spouses, 495 parents, 322 siblings, and 535 offspring. The goals of the present investigation were to analyze the covariance matrices to determine whether (a) there was evidence for sex limitation of ...
Genetic and environmental contributions to population group differences on the Raven's Progressive Matrices estimated from twins reared together and apart We carried out two studies to test the hypothesis that genetic and environmental influences explain population group differences in general mental ability...
The LISREL model of Jöreskog and Sörbom was used to perform a comparative factor analysis on intelligence data from four sex by generation groups. The covariance matrices for 10 psychometric ability measures were used to isolate Spatial and Verbal Intelligence factors. Results from a series of...
Finally, I compared variance-covariance matrices to examine past evolutionary trajectories. I found that L. bicolor has consistently lower intrapopulation genetic diversity and higher levels of isolation by distance than L. nanus. Additionally, L. nanus showed a consistent floral shift in the ...
Bounds for the Ratios of Differences of Power Means in Two Arguments The classical inequality between the weighted arithmetic and geometric means has recently been extended to means of positive definite matrices. Here we giv... O Kouba 被引量: 0发表: 2014年 ...
