Dopamine receptors and behaviour

Genetic differences between individuals can be linked to differences in behaviour. Different receptors have different abilities to bind dopamine, affecting brain activity.

Dopamine, which enhances general arousal, is made from the amino acid tyrosine. It is associated particularly with voluntary movements. People with low concentrations of dopamine have difficulty in initiating movemtn, as in Parkinson's disease.
