Sexual behavior is directed by a sophisticated interplay between steroid hormone actions in the brain that give rise to sexual arousability and experience ... JG Pfaus,TE Kippin,S Centeno - 《Hormones & Behavior》 被引量: 495发表: 2001年 The meaning of assortative mating Patterns of positive ...
In contrast to males, females raised by a pair of mixed-morph parents did not show a preference for mating partners of the opposite-sex-parent's morph. Instead, they showed a preference for males of the mother's plumage type. It is suggested that the difference in which sexual imprinting ...
The evidence available at present is consistent with the view that the two systems influence the preference behavior of the chick independently, that is, there is no internal informational exchange between them. Instead, it appears that the input to the IMHV system is selected simply as a ...
A key process of developing NIC-related addictive behaviors in rodents is NIC sensitization (SST). When NIC is repeatedly administered, its effects are enhanced so that its re-exposure later produces greater locomotor activity [2, 3]. NIC SST may have relevance to the initiation, maintenance, ...
This learning behaviour, called filial imprinting, is restricted to a sensitive period5 that lasts only a few days in the case of chicks and ducklings. There are several theories concerning the control of the time course of this sensitive period6–9, about which very little was known, ...
PURPOSE:To effectively prevent useless printouts by previously registering an imprinting function at every type of a imprinter, outputting a message reporting that an imprinting method is beyond the function of the imprinter if that happens, and stopping the imprint control of the report. CONSTITUTION...
While the above is a powerful approach for identifying imprinted expression, biological and technical biases may introduce systematic errors, hence careful experimental set-up and dedicated analyses are required to avoid this. An example of a biological feature that has to be accounted for is so-...

This DNA-methylation-dependent switch is unique to ICRs. Systematic integrations of variant and synthetic ICRs allowed us to identify the sequence requirements that are necessary and sufficient for this switch-like behavior. Furthermore, by using the ectopic ICRs as DNA-methylation-sensitive reporters ...
Parental imprinting is a unique epigenetic phenomenon in mammals, involving a group of genes that are only expressed from one parental allele, while the other allele is silenced. Proper expression of imprinted genes is essential for mammalian development, as uniparental embryos having a maternal-only...
