[Participation of the serotonin-reactive brain structure in certain forms of behavior in golden hamsters].
A viviacious play of young hamsters is shown to be accompanied by a drop of the serotonin level in the brain stem and the subsequent slumber - by its rise, while the corticosteroids content of the peripheral blood with the playful  behavior experiences no changes. Iprazid and 5-oxytryptophan inhibit the playful activity, while dioxyphenylalanina (DOPA) does not influence it. A similar depression of the serotonin level in the brain stem was also noted in an aggressive behavior and stress conditions arising when adult male-hamsters are grouped together. A conclusion is drawn to the effect that changes in the content of serotonin in the brain stem are not associated with the emotional colouration of the condition, but rather reflect the transition from the somnolence to a highly active behavior.
