I'd like to be able to answer questions such as:
- What neuro/psychological functions underly competences such as empathy (or others - see background below)?
- What neurotransmitters are of particular importance in those functions?
- What genes are known to be associated with those neurotransmitters?
Any suggestions on textbooks or review papers that would be a good starting point?
Background
I'm an M.Sc. student in epidemiology (with a psychology undergrad) and my thesis is on "gene x environment" interactions (GxE). The outcome I'm interested in is child competence (construct which can be subdivided in subcomponents such as compliance, attention & empathy) at 18 months. The main environmental predictor is mother sensitivity.
I now need to focus on some specific genes and would like to be able to choose those with a clear rationale (rather than, say, search through the literature to find the most commonly studied genes); However, at this point I lack the knowledge required to do so.
