Disuguaglianze sociali nella salute, tra eterogeneità individuale e fattori sociali di rischio
… from sociology, epidemiology, economics and behavioral genetics. In particular, I focus on two issues: the socio-economic determinants of health and BMI and the socio-economic gradient in health and BMI, trying to integrate the standard sociological approach with findings from behavior …

cGMP -Dependent Protein Kinase, Behavioral Plasticity, and Foraging in Honey Bees and Fruit Flies
Here I describe a study of comparative behavioral genetics of a complex behavioral phenotype that is affected by a gene encoding a cGMP-dependent protein kinase (PKG, foraging). I accomplish this by using a traditional genetic model---the fruit fly, Drosophila melanogaster , and a traditional …

Behavioural and neural dynamics of category learning across the menstrual cycle
… Overall, the current work bridges neuroscience, behavioral genetics and neuroendocrinology to provide a comprehensive account of learning and memory across the menstrual cycle, while also providing new methodological directions for the broader study of menstrual cycle effects on cognition.

Looking Through the Lens of Individual Differences: Relationships Between Personality, Cognitive Control, Language Processing, and Genes
… conflict. In addition, we incorporated a behavioral genetics approach to investigate this commonality at the neurotransmitter level. We explored whether genetic variation in catechol-O-methyltransferase (COMT), a gene that regulates the catabolism of dopamine in prefrontal cortex, is …

A multipronged approach to understanding how genes contribute to social behavior in threespine stickleback
… a limited molecular toolkit, often constraining behavioral genetics to mainly correlative methods rather than direct manipulation. Therefore, to enable establishing a causal relationship between genes and social behavior in the emerging model system threespine stickleback (G. aculeatus), we …

A moderated transactional link between child behavioral problems and parenting: A longitudinal- and behavioral- genetic study
Parenting behaviors and a variety of behavioral problems in children covary. The current study first aimed to examine how and why parenting and child behavioral problems are linked in middle childhood. In particular, a longitudinal design (1364 children assessed from 54 months to 5th grade) was …

Understanding Social Role Contributions to Antisocial Behavior in Adolescence and Adulthood: A Genetically Informed Approach
… design which controls for familial factors (genetics and environment), and estimated to what degree the married twin's antisociality resembles that of the unmarried co-twin (or the early parenting co-twin resembled the non-parenting co-twin). There was no evidence of pre-existing difference …

BIOLOGICAL AND ENVIRONMENTAL PREDICTORS OF EXTERNALIZING BEHAVIOR IN LATE CHILDHOOD AND ADOLESCENCE: A TWIN STUDY
This study examined the role of birth complications, delinquent peers and siblings, and specific dopamine receptors on the development of externalizing behavior in children and adolescents, along with the role of heritability in aggression and delinquency. Specifically, it was hypothesized that …

Evaluation of age differences in locomotor activity following psychostimulant administration in adolescent versus adult mice
… groups, suggesting alternative explanations for behavioral differences. Chapter 4 investigates the possibility that developmental changes in the brain may contribute to behavioral differences by examining neural activity as measured by Fos induced from cocaine in 16 different brain areas. Results …

Genetic Variation in Neurotransmitter Receptors Generates Behavioral Diversity
… Whereas diversity enriches society, extreme behavioral deviations can be pathological, so it is important to identify the causes of behavioral variability. It is clear that both the environment and genetics contribute to behavioral diversity in all animals, but the nature of the specific …
