Molecular Genetics
Studies that seek to determine the components of a trait that are heritable by identifying relevant genes and their function
Nerve Impulse
A wave of depolarization that propagates along the neuron and causes the release of neurotransmitter; action potential
A single nerve cell
Neuroscience Paradigm
A broad theoretical view that holds that mental disorders are caused in part by some aberrant process directed by the brain
Chemical substances important in transferring a nerve impulse from one neuron to another, for example, serotonin and norepinephrine

Object Relations Theory
Variant of psychoanalytic theory that focuses on the way children internalize (introject) images of the people who are important to them (their parents), such that these internalized images (object representations) become part of the go and influence how the person reacts in the real world

Second Messengers
