By means of a new photographic method to quantitate catecholamine fluorescence in tissue sections it has been possible to demonstrate a high dopamine (DA) turnover within the DA cell bodies of the midbrain. The medially located small-sized DA cell bodies of the A10 DA cell group has a very high DA turnover which was significantly different from that found in the laterally located medium-sized DA cell bodies of the A10 cell group. Thus, the mesolimbic DA pathways may be divided into two systems, the medial system having a very high DA turnover in their cell bodies which may reflect a high functional activity in this system.

Abstract
By means of a new photographic method to quantitate catecholamine fluorescence in tissue sections it has been possible to demonstrate a high dopamine (DA) turnover within the DA cell bodies of the midbrain. The medially located small-sized DA cell bodies of the A10 DA cell group has a very high DA turnover which was significantly different from that found in the laterally located medium-sized DA cell bodies of the A10 cell group. Thus, the mesolimbic DA pathways may be divided into two systems, the medial system having a very high DA turnover in their cell bodies which may reflect a high functional activity in this system.
