1. Adolescent behavior : Links to early-life stress and alcohol in male and female rats
Sammanfattning : Adolescence is an important developmental phase with large changes in behavior, physiology and neurobiology, which transform an individual from immature child to independent adult. Due to these changes, adolescence is a sensitive period for exposure to environmental factors such as stress and drug exposure; it is also a common age of onset for alcohol consumption as well as several psychiatric disorders.

2. Maternal programming: costs, benefits and constraints of maternal hormone transfer
Sammanfattning : Avian mothers convey significant quantities of androgens (i.e. ?male? steroids) to their eggs, which are known to positively influence embryonic development, post-natal growth and competitive behaviour of the offspring. However, there is large inter-female variation in the amount of androgens transferred to the eggs. LÄS MER
3. Maternal Separation in Rats : An Experimental Model for Long-Term Effects of Early Life Experiences on Neurochemistry, Voluntary Ethanol Intake and Exploration and Risk Assessment Behavior
Sammanfattning : The period of early life is important for the development of individual brain function and behavior. Human studies have shown altered vulnerability to develop psychopathology and/or excessive drug intake, possibly leading to dependence, as a consequence of early life experiences. LÄS MER
4. Development of breastfeeding behavior in preterm infants : Behavioral and neurophysiological evidence of early competence
Sammanfattning : The objectives of this thesis were to develop a method for observation of maturational steps in preterm infants' breastfeeding behavior, test the reliability and validity of this method, describe this development and explore effects of certain infant and maternal factors on infant breastfeeding behavior. The Preterm Infant Breastfeeding Behavior Scale (PIBBS) was developed. LÄS MER
5. Early Environment and Adolescent Ethanol Consumption : Effects on Endogenous Opioids and Behaviour in Rats
Sammanfattning : Excessive and compulsive ethanol drinking is one of the most serious public health issues. Therefore, it is vital to increase the knowledge about risks and protection for alcohol use disorders (AUD) to optimize prevention and treatment strategies. LÄS MER
