  • mice
  • In the present study we explore the effect of communal rearing conditions (three dams with three litters per cage) during the postnatal period on offspring (F1) and grand-offspring (F2) anxiety-like and maternal behavior in Balb/c mice. (frontiersin.org)
  • Though Balb-C mice are often considered "socially-incompetent" and high in anxiety-like behavior, our findings suggest that through enrichment of the postnatal environment, these behavioral and neuroendocrine deficits may be attenuated both within and across generations. (frontiersin.org)
  • Specificity
  • Pheromone preference, and the initiation of a complex programmed sexual behavior, is determined by the specificity of a single sex pheromone receptor protein expressed in a population of olfactory receptor neurons in the silkmoth ( Bombyx mori ). (eurekalert.org)
  • The study, which will be published on June 30th in the open-access journal PLoS Genetics , provides the first direct proof of the long-held belief that the control of sexual behavior in male moths originates in the chemical specificity of the pheromone receptor proteins expressed in pheromone receptor neurons. (eurekalert.org)
  • These results demonstrate not only that it is the specificity of the pheromone receptor proteins which controls the sexual behavior of male silkmoth, but that manipulation of the sex pheromone receptor neurons can turn silkmoths into detectors for essentially any odor for which a specific receptor can be made, due to the conspicuous orientation behavior and extremely high behavioral sensitivity of male silkmoths.

  • The reproductive biology of the chain dogfish, Scyliorhinus retifer . (springer.com)
  • Mapping the available data on reproductive biology of the Gonyleptidae on the phylogeny of the family, it is possible to infer that paternal care has evolved at least three times independently: once in the clade Progonyleptoidellinae + Caelopyginae, once in the Gonyleptinae, and once in the Heteropachylinae, which occupies a basal position within the group.

  • mechanisms
  • According to the view I am presenting, information from the environment is seen as being conveyed, via various sensory modalities, eventually to two separate hypothalamic mechanisms involved in regulating sexual behavior and pituitary gonadotropic function. (springer.com)
  • aggression
  • Studies looking for behavioral effects of BPA in children often focus on expression of general behaviors, such as aggression, anxiety or other traits, but more refined assessments are needed for boys versus girls, according to Rosenfeld. (bio-medicine.org)
  • exposure
  • A series of experiments by Rosenfeld studied the effects of prenatal exposure to bisphenol A (BPA) on later reproductive-associated behaviors using a socially and genetically monogamous rodent, the California mouse, which may better mirror most human societies than other rodents. (bio-medicine.org)
  • Rosenfeld suggests that these animal findings might provide a framework to guide human risk assessment studies in the sense that such studies may need to consider that pre- and post-natal exposure to BPA might differentially impact boys' versus girls' behaviors. (bio-medicine.org)
  • pheromone
  • The researchers, from The University of Tokyo, National Institute of Agrobiological Sciences, Fukuoka University, and Keio University, address this question using the silkmoth, which displays the simplest possible pheromone system, in which a single pheromone substance, bombykol, elicits full sexual behavior. (eurekalert.org)

  • Analysis of neuropeptide receptor levels suggest that a communal rearing environment may exert sustained effects on behavior through modification of oxytocin and vasopressin (V1a) receptor densities. (frontiersin.org)
  • Physical
  • Historians have long debated theories of illness and injury that might explain the physical deterioration and frightening, tyrannical behavior that he began to display after his 40th birthday. (smu.edu)
  • problems
  • Estrogen inhibitors and excitotoxins in pet foods can cause reproductive problems, infertility, and hyperactive, aberrant behavior! (thedogpress.com)
  • It is our assertion that we have identified the causal medical condition underlying Henry's reproductive problems and psychological deterioration," write Whitley and Kramer. (smu.edu)
  • The majority of individuals within the Kell blood group are Kell negative, so it is the rare Kell-positive father that creates reproductive problems. (smu.edu)
  • study
  • This study aimed at assessing their sexual behaviors and SRH needs and identifying factors associated with marriage concerns and a desire to have children. (springer.com)
  • display
  • In adulthood, communally reared offspring were observed to display reduced anxiety-like behavior when placed in a novel environment. (frontiersin.org)
  • ways
  • My objective in this brief presentation is to describe some of the ways in which one can look at reproductive behavior within the framework of an overall neuroendocrine scheme, an approach to which Danny Lehrman made such pioneering contributions. (springer.com)

  • Just over thirty years ago, the EPA banned PCBs from the USA but this chemical (which causes cancer and reproductive toxicity) isstill found in fish from which the oil is extracted. (thedogpress.com)

  • But the dramatic changes in his personality provide stronger evidence that Henry had McLeod syndrome, the authors point out: His mental and emotional instability increased in the dozen years before death to an extent that some have labeled his behavior psychotic. (smu.edu)
