| The changes and control of emotion were related to the changes in the levels of monoamines and its metabolites in the limbic system of the brain stem. |
| Estrogen and progesterone seem to modulate levels of monoamines, including serotonin. |
| While hyperforin may be sufficient to explain the antidepressant effects of St. John's wort, synergistic effects on monoamines is possible. |
| Therefore, it appears likely that aggression is moderated by a variety of neuromodulators, including monoamines, neuropeptides and neurosteriods. |
| Beta adrenergics, other monoamines, and acetylcholine did not restore this transport. |
| Interest has focused recently on the responses of central brain monoamines, specifically the catecholamines and indoleamines in response to stress. |
