Nortriptyline mediates behavioral effects without affecting hippocampal cytogenesis in a genetic rat depression model

Petersén Å, Wörtwein G, Gruber SH, El-Khoury A and Mathé AA.Neuroscience Letters 451(2): 148-151 (2009)AbstractA prevailing hypothesis is that neurogenesis is reduced in depression and that the common mechanism for antidepressant treatments is to increase it in adult hippocampus. Reduced neurogenesis has been shown in healthy rats exposed to stress, but it has not yet been demonstrated in depresse
