title: Two types of dopamine receptors in behavioral regulation.
abstract: Evidence has been presented indicating the existence of distinct dopamine receptors in the brain. The experimental proof that two types of dopamine receptors--the excitation-mediating (DAe) receptors and the inhibition-mediating (DAi) receptors--exist in the snail brain is put forward. The functioning of DAi and DAe receptors in locomotor activity and stereotyped behavior is discussed along with implications of dopaminergic involvement in a gratification system.
