They are xed, but even though you have it, they can turn on and off as determined by environment or psychobiological factors) Phenotype (totality of observable behavioral characteristics, which changes over time. Four methods to study behavioral genetics (if someone has a predisposition) Monozygotic (mz) twins (100% genetic overlap) they may have the genotypes, but it may never switch on. Adoptees method twins who are raised with different parents-not the same environment. Reuptake: analysis the absorption by a presynaptic nerve ending of a neurotransmitter that it has secreted. Cortical vs subcortical structures of the brain cortical: higher order cognition (learn, plan) Subcortical: within the brain, lower order (awake, asleepness) Structure and function of the human brain (behavior neuroanatomy) Right side retrieval, psychotic symptoms (such as mania/depression)
