Abstract
P-Chlorophenylalanine treatment eliminated the normal male rat preference for the female preputial gland odor. Oral adminiatration of hydrocortisone had a similar effect on dimethyl sulfite preference, which slowly reappeared after the discontinuance of the treatment. These changes of behavior are discussed in relation to possible serotonin alterations resulting from the treatments.
