Abstract

Levels of catecholamine content assayed by a sensitive radiometric technique were compared to semi-quantitative visual estimation of the histofluorescence in different regions of brain after amine depletion by varying doses of reserpine. The range over which fluorescence of varicose terminals appeared to diminish is only about 20–40% of the normal catecholamine content. The level of this range varied with the area examined. The percent of normal catecholamine levels at which fluorescence was first noticed to be decreased from normal, and that at which fluorescence seemed to disappear were relatively close and both appeared to be linearly correlated to the logarithm of the normal catecholamine content. In areas with a normally high catecholamine content, a greater percentage decrease in amine content was required to make a noticeable decrease in fluorescence than was required in areas with a normally lower catecholamine content.
